145-567: Novgorod won its independence in 1136 after the Novgorodians deposed their prince and the Novgorod veche began to elect and dismiss princes at its own will. The veche also elected the posadnik , who was the chief executive of the city, and from 1156, the archbishop of Novgorod , subject to approval by the Russian metropolitan . The tysyatsky was also elected by the veche , who

290-447: A contract called a ryad ( Russian : ряд ), which protected the interests of Novgorodian boyars and laid out the prince's rights and responsibilities. The ryads that have been preserved in archives describe the relationship of Novgorod with twelve invited princes: five of them from Tver, four from Moscow, and three from Lithuania. First and foremost among the prince's functions, he was a military leader. He also patronized churches in

435-476: A stepennoy posadnik . Posadniks were almost invariably boyars – the city's highest aristocracy. The precise makeup of the veche is also uncertain, although it appears to have comprised members of the urban population, as well as of the free rural population. Whether it was a democratic institution or one controlled by the boyars has been hotly debated. The posadniks, tysiatskys, and even the bishops and archbishops of Novgorod, were often elected or at least approved by

580-463: A cousin of Ivan III, to be accepted. According to tradition, Marfa Boretskaya , the wife of the posadnik Isak Boretsky, was the main proponent of an alliance with Poland–Lithuania to save the republic. According to this legend, Boretskaya invited the Lithuanian princeling Mikhailo Olelkovich and asked him to become her husband and the ruler of Novgorod. She also concluded an alliance with Casimir ,

725-596: A critical conflict took place between Moscow and Novgorod, when Moscow annexed the Dvina Lands along the course of the Northern Dvina . These lands were crucial to Novgorod's well-being since much of the city's furs came from there. This territory was returned to Novgorod the following year. In the 12th to 15th centuries, the Novgorod Republic expanded east and northeast. The Novgorodians explored

870-622: A foothold in Karelia . On August 12, 1323, Sweden and Novgorod signed the Treaty of Nöteborg , regulating their border for the first time. The Novgorod Republic was saved from the direct impact of the Mongol invasions as it was not conquered by the Mongols. In 1259, Mongol tax-collectors and census-takers arrived in the city, leading to political disturbances and forcing Alexander Nevsky to punish

1015-462: A large measure of democratic participation far in advance of the rest of Europe, but that share several similarities with the democratic traditions of Scandinavian peasant republics . The people had the power to elect city officials and they even had the power to elect and remove the prince. The Chronicle writer then goes on to describe a "town meeting" where these decisions would have been made, which included people from all social classes ranging from

1160-693: A number of continental shelves , including the Canadian Arctic shelf, underlying the Canadian Arctic Archipelago , and the Russian continental shelf , which is sometimes called the "Arctic Shelf" because it is larger. The Russian continental shelf consists of three separate, smaller shelves: the Barents Shelf, Chukchi Sea Shelf and Siberian Shelf . Of these three, the Siberian Shelf is the largest such shelf in

1305-446: A number of pro-Lithuanian boyars and confiscating their lands. In 1478, Ivan III sent his army to take direct control of the city. He destroyed the veche , tore down the veche bell, the ancient symbol of participatory governance, civil society, and legal rights, and destroyed the library and archives , thus ending the independence of Novgorod. After the takeover, Ivan took more than four-fifths of Novgorod's land: half for himself and

1450-453: A number of town officials (by cutting off their noses) for defying him as the grand prince of Vladimir (soon to be the khan's tax-collector in Russia) and his Mongol overlords. Prince of Novgorod The Prince of Novgorod ( Russian : князь новгородский , romanized :  knyaz novgorodsky ) was the title of the ruler of Novgorod in present-day Russia. From 1136, it was

1595-507: A protracted series of wars with Moscow beginning in the late 14th century in order to keep these lands. Losing them meant economic and cultural decline for the city and its inhabitants. The ultimate failure of the Novgorodians to win these wars led to the downfall of the Novgorod Republic. Novgorod supported Dmitry Shemyaka against Vasily Vasilievich in the Muscovite War of Succession (1425–1453). After Vasily II returned to throne,

1740-624: A repudiation of the Treaty of Yazhelbitsy (1456), and went to war against the city. The army of Moscow won a decisive victory in the Battle of Shelon River in July 1471, which severely limited Novgorod's freedom to act thereafter, although the city maintained its formal independence. For the next six years, pro-Moscow and anti-Moscow factions in Novgorod competed with one another. Ivan III visited Novgorod several times during this period, persecuting

1885-408: A secular nature, and carried out other secular tasks. However, the archbishops appear to have worked with the boyars to reach a consensus and almost never acted alone. The archbishop was not appointed, but elected by Novgorodians, and approved by the metropolitan bishop of Russia . The archbishops were probably the richest single land-owners in Novgorod, and they also made money off court fees, fees for

2030-536: A struggle with Novgorod for the Russian fur trade , and thus, an economic rivalry for fur, land and trade ports. Some Novgorodian boyars were opposed to Moscow as a result, while others pursued a pro-Muscovite policy in the hopes that good relations with Moscow would reduce disruption in Novgorod's trade ; Novgorod was also dependent on the Russian lands to its southwest for important imports such as grain. Some Novgorodians were also attracted to Moscow due to it being

2175-406: A war between Moscow and Novgorod took place, which ended after the Treaty of Yazhelbitsy was signed in 1456. The treaty marked the beginning of the fall of Novgorod's independence as it lost certain freedoms. Moscow began to gradually seize land in the northern territories that were formerly under Novgorod's control for the next decade and half due to a desire for luxury furs in the area. This led to

2320-716: Is Molloy Hole in the Fram Strait , at about 5,550 m (18,210 ft). The two major basins are further subdivided by ridges into the Canada Basin (between Beaufort Shelf of North America and the Alpha Ridge ), Makarov Basin (between the Alpha and Lomonosov Ridges), Amundsen Basin (between Lomonosov and Gakkel ridges), and Nansen Basin (between the Gakkel Ridge and the continental shelf that includes

2465-414: Is a section referred to as the sub-surface layer. It is a product of Atlantic water that enters through canyons and is subjected to intense mixing on the Siberian Shelf. As it is entrained, it cools and acts a heat shield for the surface layer on account of weak mixing between layers. However, over the past couple of decades a combination of the warming and the shoaling of Atlantic water are leading to

2610-477: Is cloudy year-round, with mean cloud cover ranging from 60% in winter to over 80% in summer. The temperature of the surface water of the Arctic Ocean is fairly constant at approximately −1.8 °C (28.8 °F), near the freezing point of seawater . The density of sea water, in contrast to fresh water, increases as it nears the freezing point and thus it tends to sink. It is generally necessary that

2755-565: Is contained in a polar climate characterized by persistent cold and relatively narrow annual temperature ranges. Winters are characterized by the polar night , extreme cold, frequent low-level temperature inversions, and stable weather conditions. Cyclones are only common on the Atlantic side. Summers are characterized by continuous daylight ( midnight sun ), and air temperatures can rise slightly above 0 °C (32 °F). Cyclones are more frequent in summer and may bring rain or snow. It

2900-427: Is not definitely known; the country was divided into several tysyachi ( Russian : тысячи , lit.   'thousands') in the core lands of the country, and volosti ( Russian : волости ) in lands in the east and north that were being colonized or just paid tribute. The city of Novgorod and its vicinity, as well as a few other towns, were not part of any of those. Pskov achieved autonomy from Novgorod in

3045-653: Is now in northwestern Russia . As a result, in Russian historiography, Novgorod is traditionally seen as the birthplace of the country's monarchy . The Primary Chronicle (PVL) states that when Oleg the Wise conquered Kiev (modern Kyiv ) in 882, which marks the founding of Kievan Rus' , he ordered Novgorod to pay the Varangian princes in Kiev 300 grivny a year. In 1014, the PVL mentions this tribute had increased: "When Yaroslav

3190-677: Is predominantly cyclonic on the Eurasian side and anticyclonic in the Canadian Basin . Water enters from both the Pacific and Atlantic Oceans and can be divided into three unique water masses. The deepest water mass is called Arctic Bottom Water and begins around 900 m (3,000 ft) depth. It is composed of the densest water in the World Ocean and has two main sources: Arctic shelf water and Greenland Sea Deep Water. Water in

3335-495: Is the highest volumetric inflow to the Arctic Ocean, equalling about 10 times that of the Pacific inflow, and it creates the Arctic Ocean Boundary Current. It flows slowly, at about 0.02 m/s. Atlantic Water has the same salinity as Arctic Bottom Water but is much warmer (up to 3 °C [37 °F]). In fact, this water mass is actually warmer than the surface water and remains submerged only due to

3480-420: Is unclear. Many were between various boyar factions or, if a revolt did involve the peasants or tradesmen against the boyars, it did not consist of the peasants wanting to overthrow the existing social order, but was more often than not a demand for better rule on the part of the ruling class. There did not seem to be a sense that the office of prince should be abolished or that the peasants should be allowed to run

3625-563: The Life of Alexander Nevsky . Novgorod was also spared by the Mongol armies during the Mongol invasions after Alexander Nevsky agreed to pay tribute. Historians such as J. L. I. Fennell have called the proportions of Nevsky's victories as having been overblown; he also argued that there was no existence of a unified Western scheme of aggression against Russia and that Nevsky appeased the Mongols, while many Russian historians have argued that Nevsky

3770-687: The Arctic Mediterranean Sea . It has also been described as an estuary of the Atlantic Ocean . It is also seen as the northernmost part of the all-encompassing world ocean . The Arctic Ocean includes the North Pole region in the middle of the Northern Hemisphere and extends south to about 60°N . The Arctic Ocean is surrounded by Eurasia and North America, and the borders follow topographic features:

3915-744: The Bering Strait on the Pacific side and the Greenland Scotland Ridge on the Atlantic side. It is mostly covered by sea ice throughout the year and almost completely in winter . The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; its salinity is the lowest on average of the five major oceans, due to low evaporation , heavy fresh water inflow from rivers and streams, and limited connection and outflow to surrounding oceanic waters with higher salinities. The summer shrinking of

4060-608: The Cretaceous period, the Canadian Basin opened, and tectonic activity due to the assembly of Alaska caused hydrocarbons to migrate toward what is now Prudhoe Bay. At the same time, sediments shed off the rising Canadian Rockies built out the large Mackenzie Delta. The rifting apart of the supercontinent Pangea , beginning in the Triassic period, opened the early Atlantic Ocean. Rifting then extended northward, opening

4205-508: The Daniilovichi of Moscow did. Arctic Ocean Main five oceans division: Further subdivision: The Arctic Ocean is the smallest and shallowest of the world's five oceanic divisions . It spans an area of approximately 14,060,000 km (5,430,000 sq mi) and is the coldest of the world's oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it

4350-638: The East–West Schism , Novgorod struggled from the beginning of the 13th century against Swedish, Danish, and German crusaders. During the Swedish–Novgorodian Wars , the Swedes invaded lands where some of the population had earlier paid tribute to Novgorod. The Germans had been trying to conquer the Baltic region since the late 12th century. Novgorod went to war 26 times with Sweden and 11 times with

4495-614: The Eurasian Basin , which is 4,000–4,500 m (13,100–14,800 ft) deep, and the Amerasian Basin (sometimes called the North American or Hyperborean Basin), which is about 4,000 m (13,000 ft) deep. The bathymetry of the ocean bottom is marked by fault block ridges, abyssal plains , ocean deeps , and basins. The average depth of the Arctic Ocean is 1,038 m (3,406 ft). The deepest point

4640-655: The Franz Josef Land ). The crystalline basement rocks of mountains around the Arctic Ocean were recrystallized or formed during the Ellesmerian orogeny, the regional phase of the larger Caledonian orogeny in the Paleozoic Era. Regional subsidence in the Jurassic and Triassic periods led to significant sediment deposition, creating many of the reservoirs for current day oil and gas deposits. During

4785-572: The Grand Duchy of Lithuania , and elsewhere, also vied for the Novgorodian throne. Thus, Novgorod did not really choose its prince, but considering the political climate, they often very prudently went with the most senior or most powerful prince in the land if he did not impose himself (or his candidate) upon them. What was different about Novgorod, then, was not so much that Novgorod could freely choose its princes – it could not. Rather, what

4930-584: The Independence I and Independence II cultures of northeastern Canada and Greenland ( c.  2400–1800 BC and c.  800–1 BC ); and the Groswater of Labrador and Nunavik . The Dorset culture spread across Arctic North America between 500 BC and AD 1500. The Dorset were the last major Paleo-Eskimo culture in the Arctic before the migration east from present-day Alaska of

5075-632: The Livonian Brothers of the Sword . The German knights , along with Danish and Swedish feudal lords, launched a series of uncoordinated attacks in 1240–1242. Russian sources mention that a Swedish army was defeated in the Battle of the Neva in 1240. The Baltic German campaigns ended in failure after the Battle on the Ice in 1242. After the foundation of the castle of Vyborg in 1293 the Swedes gained

5220-619: The Northern Crusades , the Novgorodian prince Alexander Yaroslavich defeated the Swedes at the Battle of the Neva in July 1240, from which he received the sobriquet Nevsky ("of the Neva"). Alexander then defeated German crusaders at the Battle on the Ice in 1242, after the forces of the exiled prince of Pskov and men from the Bishopric of Dorpat attacked Pskov Land and Votia , a tributary of Novgorod. This later led to him being depicted as an ideal ruler in chronicles such as

5365-670: The Northwest Passage , to " Cathay " ( China ) caused water to win out, and by 1723 mapmakers such as Johann Homann featured an extensive "Oceanus Septentrionalis" at the northern edge of their charts. The few expeditions to penetrate much beyond the Arctic Circle in that era added only small islands, such as Novaya Zemlya (11th century) and Spitzbergen (1596), though, since these were often surrounded by pack-ice , their northern limits were not so clear. The makers of navigational charts , more conservative than some of

5510-643: The Thule people , ancestors of the modern Inuit . The Thule Tradition lasted from about 200 BC to AD 1600, arising around the Bering Strait and later encompassing almost the entire Arctic region of North America. The Thule people were the ancestors of the Inuit, who now live in Alaska, Northwest Territories , Nunavut , Nunavik (northern Quebec), Labrador and Greenland. For much of European history ,

5655-763: The Volga trade route and the route from the Varangians to the Greeks along the Dnieper River system. A vast array of goods were transported along these routes and exchanged with local Novgorod merchants and other traders. The merchants of Gotland retained the Gothic Court trading house well into the 12th century. Later, German merchantmen also established trading houses in Novgorod. Scandinavian royalty would intermarry with Russian princes and princesses. After

5800-630: The northwest and north of European Russia , as well as the eastern part of Finland . To the east, it was bordered by the Principality of Tver and to the west, it was bordered by Lithuania as well as various Baltic powers, including the Teutonic Order and the bishoprics of Dorpat and Courland as well as the Hanseatic cities of Riga and Reval . The economy of the Novgorod Republic included farming and animal husbandry (e.g.,

5945-411: The posadniki (burgomaster), to the chernye liudi ( lit.   ' black folks ' ) or the lowest free class. The precise constitution of the medieval Novgorodian republic is uncertain, although traditional histories have created the image of a highly institutionalized network of veches (public assemblies) and a government of posadniki (burgomaster), tysyatskys ("thousandmen"; originally

Novgorod Republic - Misplaced Pages Continue

6090-472: The prince of Moscow (who was almost always the grand prince of Vladimir ) was usually the prince of Novgorod as well. As Moscow grew in power in the 15th century, Novgorod began to lose its autonomy. In a 1471 peace treaty with Moscow following the Battle of Shelon , Novgorod pledged allegiance to Moscow, with its system of government temporarily left intact. The end of the republic and the veche came in 1478 when Ivan III once again invaded and seized

6235-428: The 1130s mentioned 30 administrative posts in the territory of Novgorod, where revenues were collected regularly and sent as a tithe to the Novgorod bishop. Throughout the 12th century, Novgorod utilized the Baltic - Volga - Caspian trade route, not only for trading but also for bringing food from the fertile Oka region to their city. In 1136, the Novgorodians dismissed their prince Vsevolod Mstislavich , and over

6380-423: The 12th century, while most are from after 1262. Thus it is difficult to determine Novgorod's political structure due to the paucity of sources. The prince, while his status in Novgorod was not inheritable and his power was much reduced, remained an important figure in Novgorodian life. Of around 100 princes of Novgorod, many, if not most, were invited in or dismissed by the Novgorodians. At least some of them signed

6525-424: The 13th century; its independence was confirmed by the Treaty of Bolotovo in 1348. Several other towns had special status as they were owned jointly by Novgorod and one of the neighbouring states. The Novgorod Republic was the largest of the Russian states in terms of area until it was surpassed by Moscow following its annexation of other independent principalities in the 15th century. The Novgorod Republic occupied

6670-584: The 9th century when, according to tradition, the Varangian chieftain Rurik and his brothers were invited to rule over the East Slavic and Finnic tribes of northwest Russia , but reliable information about it dates only to the late 10th century when Vladimir , the youngest son of Sviatoslav I , was made the prince of Novgorod. During the reign of Ivan III , the title was restored and Novgorod

6815-677: The Arctic Ocean as mafic oceanic crust material erupted out of a branch of Mid-Atlantic Ridge. The Amerasia Basin may have opened first, with the Chukchi Borderland moved along to the northeast by transform faults. Additional spreading helped to create the "triple-junction" of the Alpha-Mendeleev Ridge in the Late Cretaceous epoch . Throughout the Cenozoic Era, the subduction of the Pacific plate,

6960-617: The Arctic Ocean has a uniquely complex system of water flow. It resembles some hydrological features of the Mediterranean Sea , referring to its deep waters having only limited communication through the Fram Strait with the Atlantic Basin , "where the circulation is dominated by thermohaline forcing". The Arctic Ocean has a total volume of 18.07 × 10 km , equal to about 1.3% of the World Ocean. Mean surface circulation

7105-581: The Arctic Ocean. Much of the Arctic ice pack is also covered in snow for about 10 months of the year. The maximum snow cover is in March or April—about 20–50 cm (7.9–19.7 in) over the frozen ocean. The climate of the Arctic region has varied significantly during the Earth's history. During the Paleocene–Eocene Thermal Maximum 55 million years ago, when the global climate underwent

7250-653: The Arctic Ocean: Different authorities put various marginal seas in either the Arctic Ocean or the Atlantic Ocean, including: Hudson Bay , Baffin Bay , the Norwegian Sea , and Hudson Strait . The main islands and archipelagos in the Arctic Ocean are, from the prime meridian west: There are several ports and harbours on the Arctic Ocean. The ocean's Arctic shelf comprises

7395-462: The Baltic trade network established by the Hanseatic League . From Novgorod's northeastern lands ("The Lands Beyond the Portages" as they were called in the chronicles), the area stretching north of Lakes Ladoga and Onega up to the White Sea and east to the Ural Mountains had so much fur that medieval travel accounts tell of furry animals raining from the sky. The Novgorodian merchants traded with Swedish, German, and Danish cities. In early years,

7540-408: The Canadian Archipelago. As noted, the process of ice formation and movement is a key driver in Arctic Ocean circulation and the formation of water masses. With this dependence, the Arctic Ocean experiences variations due to seasonal changes in sea ice cover. Sea ice movement is the result of wind forcing, which is related to a number of meteorological conditions that the Arctic experiences throughout

7685-453: The Catholic faith: Thus did Great Prince Ivan advance with all his host against his domain of Novgorod because of the rebellious spirit of its people, their pride and conversion to Latinism. With a great and overwhelming force did he occupy the entire territory of Novgorod from frontier to frontier, inflicting on every part of it the dread powers of his fire and sword. The city-state of Novgorod had developed procedures of governance that held

7830-408: The European region of the Arctic Ocean was heavily contested : the Allied commitment to resupply the Soviet Union via its northern ports was opposed by German naval and air forces. Since 1954 commercial airlines have flown over the Arctic Ocean (see Polar route ). The Arctic Ocean occupies a roughly circular basin and covers an area of about 14,056,000 km (5,427,000 sq mi), almost

7975-410: The Fram Strait is what allows for both inflow and outflow on the Atlantic side of the Arctic Ocean. Because of this, it is influenced by the Coriolis force , which concentrates outflow to the East Greenland Current on the western side and inflow to the Norwegian Current on the eastern side. Pacific water also exits along the west coast of Greenland and the Hudson Strait (1–2 Sv), providing nutrients to

8120-419: The Lomonosov Ridge, which appears to be continental crust separated from the Barents-Kara Shelf in the Paleocene and then starved of sediment. It may contain up to 10 billion barrels of oil. The Gakkel Ridge rift is also poorly understand and may extend into the Laptev Sea. In large parts of the Arctic Ocean, the top layer (about 50 m [160 ft]) is of lower salinity and lower temperature than

8265-444: The North American polar region goes back at least 17,000–50,000 years, during the Wisconsin glaciation . At this time, falling sea levels allowed people to move across the Bering land bridge that joined Siberia to northwestern North America (Alaska), leading to the Settlement of the Americas . Early Paleo-Eskimo groups included the Pre-Dorset ( c.  3200–850 BC ); the Saqqaq culture of Greenland (2500–800 BC);

8410-721: The Novgorodians sailed the Baltic themselves (several incidents involving Novgorodian merchants in Gotland and Denmark are reported in the Novgorodian First Chronicle ). Orthodox churches for Novgorodian merchants have been excavated on Gotland . Likewise, merchants from Gotland had their own St. Olaf church and trading house in Novgorod. However, the Hanseatic League disputed the right of Novgorodian merchants to carry out sea trade independently and to deliver cargoes to Western European ports by their own ships. Silver, cloth, wine and herring were imported from Western Europe. The amount of fur, especially squirrel and other relatively cheap furs, that Novgorod supplied to Hanseatic merchants

8555-577: The Pskovian army, while the pretender was captured, handed over to Yaroslav of Suzdal and imprisoned in Pereslavl-Zalessky . In 1234, Yaroslav of Suzdal campaigned against the bishopric of Dorpat. The 1234 peace agreement was based on that of 1224; it did not involve any territorial issues, but only a prisoner exchange and Dorpat's promise to stop supporting factions in Pskov and Novgorod that opposed Yaroslav of Suzdal. Yaroslav went to Kiev in 1235, leaving his 15- or 16-year-old son Aleksandr Yaroslavich behind in Novgorod. According to Russian sources, during

8700-480: The Republic's hunger. In autumn 1231, Yaroslav took Novgorodian troops on a campaign to Chernigov against his rival Michael. In 1232, there were anti-Yaroslav rebellions in Novgorod and Pskov, but only the latter was successful in chasing the Suzdalians out of town. In 1233, Boris Negochevich and other Novgorodian nobles joined forces with Yaroslav Vladimirovich (pretender-prince of Pskov) and some Sword Brothers, occupying Izborsk in 1233, but they were soon expelled by

8845-455: The Suzdalian dynasty's power grew amongst citizens of both Pskov and Novgorod. As they rejected support for his campaign against Riga, suspecting a ploy to seize Pskov along the way after the previous failed attempt, Yaroslav was forced to abandon his plans and disband his expensive army. When a bad harvest exacerbated the famine,the Novogorodians rose in revolt against the prince, who fled with his family and supporters to Pereslavl-Zalessky . With

8990-489: The Suzdalian princely threat gone, the Pskovians sent the Livonian auxiliaries home, while the veche elected Michael of Chernigov as Novgorod's new knyaz in 1230. The NPL notes that in subsequent years, Pskov remained allied with Riga and the Rigans, and later Dorpat (modern Tartu ) and Odenpäh (modern Otepää ). Meanwhile, Yaroslav Vladimirovich, a son of the previous Pskovian prince Vladimir Mstislavich of Pskov  [ et ] sought to leverage his family ties with

9135-404: The Varangians at the death of Yaroslav the Wise (1054). Chronicles state that the Novgorodians paid tribute to the grand prince of Kiev by 1113. Some time after this, the administration of the principality seemed to have matured. The Novgorodian tysyatsky and posadniki appointed boyars from the cities and collected revenues for administration in the territories it held. A charter from

9280-535: The archbishops of Novgorod and others raised horses for the Novgorodian army), while hunting , beekeeping , and fishing were also widespread. In most of the regions of the republic, these different "industries" were combined with farming. Iron was mined on the coast of the Gulf of Finland . Staraya Russa and other localities were known for their saltworks . Flax and hop cultivation were also of significant importance. Countryside products, such as furs, beeswax , honey , fish, lard , flax, and hops, were sold on

9425-399: The areas around Lake Onega , along the Northern Dvina , and coastlines of the White Sea . At the beginning of the 14th century, the Novgorodians explored the Arctic Ocean , the Barents Sea , the Kara Sea , and the West-Siberian river Ob . The lands to the north of the city, rich with fur , sea fauna and salt among others were of great economic importance to the Novgorodians, who fought

9570-467: The auspices of Ivan III and his son Ivan Ivanovich . The Novgorod Judicial Charter, along with the Pskov Judicial Charter , were later used for Ivan III's Sudebnik of 1497 which served as the legal code for the entire Russian state. Novgorod was called a republic by Sigismund von Herberstein in his Notes on Muscovite Affairs written at least half a century after the conquest of Novgorod. Soviet-era Marxist scholarship frequently described

9715-608: The average winter value of 15,600,000 km (6,023,200 sq mi). The seasonal variations are about 7,000,000 km (2,702,700 sq mi), with the maximum in April and minimum in September. The sea ice is affected by wind and ocean currents, which can move and rotate very large areas of ice. Zones of compression also arise, where the ice piles up to form pack ice. Icebergs occasionally break away from northern Ellesmere Island , and icebergs are formed from glaciers in western Greenland and extreme northeastern Canada. Icebergs are not sea ice but may become embedded in

9860-415: The beginning of Russian history, two Russian principalities, Novgorod and Rostov-Suzdal, were engaged in exploring, conquering, exploiting, and colonizing the area west of the Ural Mountains". From the late 11th century, the Novgorodians asserted greater control over the determination of their rules, and rejected a politically dependent relationship to Kiev. The PVL claims that Novgorod ceased paying tribute to

10005-434: The beginning of the 9th century to try to form a negotiated settlement to end military aggression amongst each other. According to the legendary calling of the Varangians (recorded in diverging variations in the Primary Chronicle and Novgorod First Chronicle ), in the year 862, the Varangian brothers Rurik , Sineus and Truvor were each "invited" to reign in Novgorod, Beloozero , and Izborsk , respectively, in what

10150-545: The bishops Hermann of Dorpat and Albert of Riga (died 1229) to gain his father's throne. The famine in Novgorod continued, and in 1230 another popular revolt erupted against supporters of the brand new prince Michael of Chernigov, including tysiatskii Boris Negochevich. The desperate Novgorodian people asked for Yaroslav of Suzdal to return, which he did at the end of 1230, but the famine got even worse in spring 1231, until German merchants sailing from overseas were able to import sufficient amounts of grain and flour to relieve

10295-441: The boyars' wealth would flow to the grand prince and Muscovite boyars, and the Novgorodians would fall into decline; most of them also did not earn enough to pay for war. By 1470, with the pro-Lithuanian faction being dominant, the Novgorodian boyars questioned Ivan's sovereignty over Novgorod as their prince. Novgorod negotiated with the Grand Duchy of Lithuania for a new prince to be sent over. This led to Mikhailo Olelkovich ,

10440-404: The boyars. The Cathedral of St. Sophia – the main ecclesiastic establishment of Novgorod – was their chief rival in terms of landownership . Its votchinas were located in the most economically developed regions of Novgorod Land. The Yuriev Monastery , Arkazhsky Monastery , Antoniev Monastery and some other privileged monasteries are known to have been big landowners. There were also

10585-458: The center of Russian Orthodoxy as opposed to Lithuania, where Catholicism was dominant and its culture was being increasingly polonized , though some Novgorodian clergy adopted a pro-Lithuanian policy for political reasons due to fears that embracing the grand prince of Moscow would eventually lead to the end of Novgorod's independence. Most Novgorodian boyars had hoped to maintain the republic's independence since if Novgorod were to be conquered,

10730-583: The city (there was a Carpenter's End and a Potters' End, for example). The merchants were organised into associations, of which the most famous were those of wax traders (called Ivan's Hundred ) and of the merchants engaged in overseas trade. Like much of the rest of Novgorod's medieval history, the precise composition of these organizations is uncertain. It is quite possible that the "ends" and "streets" were simply neighborhood administrative groups rather than guilds or "unions". Street organizations were known to build churches in their neighborhoods and to have buried

10875-442: The city and held court, although it was often presided over by his namestnik or lieutenant when he was personally absent from the city. The posadnik had always to be present in the court and no court decision could be made without his approval. Also, without the posadnik's approval the prince could neither give out Novgorod lands nor issue laws. Besides, the prince could not own land in Novgorod and could not himself collect taxes from

11020-578: The city as part of his campaign to annex all other Russian states. The state was called Novgorod and Great Novgorod ( Russian : Великий Новгород , romanized :  Velikiy Novgorod ) with the form Sovereign Lord Novgorod the Great ( Russian : Государь Господин Великий Новгород , romanized :  Gosudar' Gospodin Velikiy Novgorod ) becoming common in the 15th century. Novgorod Land and Novgorod volost usually referred to

11165-519: The city, more powerful princes could assert their power independently over the city, as did Mstislav the Bold in the early 13th century, Alexander Nevsky in the 1240s and 1250s, his brother Iaroslav in the 1260s and 1270s, and others. According to a remark in the chronicles, Novgorod had the right, after 1196, to pick their prince of their own free will, but again, evidence suggests that even after that, princes were chosen and dismissed only about half

11310-501: The city. Throughout the republican period, the archbishop of Novgorod was the head of the Orthodox church in the city. The Finnic population of Novgorod Land underwent Christianization. The sect of the strigolniki spread to Novgorod from Pskov in the middle of the 14th century, with its members renouncing ecclesiastic hierarchy, monasticism and sacraments of priesthood, communion, repentance and baptism, before they disappeared by

11455-694: The collision of India with Eurasia, and the continued opening of the North Atlantic created new hydrocarbon traps. The seafloor began spreading from the Gakkel Ridge in the Paleocene Epoch and the Eocene Epoch, causing the Lomonosov Ridge to move farther from land and subside. Because of sea ice and remote conditions, the geology of the Arctic Ocean is still poorly explored. The Arctic Coring Expedition drilling shed some light on

11600-401: The dead of their neighborhoods during outbreaks of the plague, but beyond that their activities are uncertain. "Streets" and "ends" may have taken part in political decision-making in Novgorod in support of certain boyar factions or to protect their interests. Merchant "elders" are also noted in treaties and other charters, but only about a hundred of these charters exist. A half dozen date from

11745-548: The dominance of rich merchant families in politics. Some scholars argue that the archbishop was the head of the executive branch of the government, although it is difficult to determine the exact competence of the various officials. It is possible that there was a Council of Lords ( Russian : Совет Господ ) that was headed by the archbishop and met in the archiepiscopal palace (and in the Chamber of Facets after 1433). The executives of Novgorod, at least nominally, were always

11890-721: The early 15th century. Another sect, known as the Heresy of the Judaizers by its opponents, appeared in Novgorod in the second half of the 15th century and subsequently enjoyed support at the court in Moscow, before ultimately they were persecuted and several councils of the Russian Church condemned them. Like other Russian states, the military of Novgorod consisted of a levy and the prince's retinue ( druzhina ). While potentially all free Novgorodians could be mobilised, in reality

12035-501: The explorers who travelled closer and closer to the pole reported, the polar ice cap is quite thick and persists year-round. Fridtjof Nansen was the first to make a nautical crossing of the Arctic Ocean, in the Fram Expedition from 1893 to 1896. The first surface crossing of the ocean was led by Wally Herbert in 1969, in a dog sled expedition from Alaska to Svalbard , with air support. The first nautical transit of

12180-574: The formation of Atlantic Deep Water. The overturning of this water plays a key role in global circulation and the moderation of climate. In the depth range of 150–900 m (490–2,950 ft) is a water mass referred to as Atlantic Water. Inflow from the North Atlantic Current enters through the Fram Strait, cooling and sinking to form the deepest layer of the halocline, where it circles the Arctic Basin counter-clockwise. This

12325-416: The head of the town militia, but later a judicial and commercial official), other members of aristocratic families, and the archbishops of Novgorod . The veche tradition convinced Novgorodians that they had the right to be consulted on important issues, though in practice, the posadniki came from a few rich merchant families. In the early years of the republic, the prince and posadnik shared power until

12470-456: The ice has been quoted at 50%. The US National Snow and Ice Data Center (NSIDC) uses satellite data to provide a daily record of Arctic sea ice cover and the rate of melting compared to an average period and specific past years, showing a continuous decline in sea ice extent. In September 2012, the Arctic ice extent reached a new record minimum. Compared to the average extent (1979–2000), the sea ice had diminished by 49%. Human habitation in

12615-497: The increasing influence of Atlantic water heat in melting sea ice in the eastern Arctic. The most recent estimates, for 2016–2018, indicate the oceanic heat flux to the surface has now overtaken the atmospheric flux in the eastern Eurasian Basin. Over the same period the weakening halocline stratification has coincided with increasing upper ocean currents thought to be associated with declining sea ice, indicate increasing mixing in this region. In contrast direct measurements of mixing in

12760-531: The key fortress of Orekhov . The Pskovites sent a small detachment and took advantage of the situation by only agreeing to accompany the Novgorodian army on the condition that Pskov would be formally granted its independence. Novgorod sent an allied force to lay siege to the fortress and signed the Treaty of Bolotovo (1348) on the way to Orekhov. As per the terms of the treaty, the posadniki of Novgorod no longer had any administrative or judicial function in Pskov and

12905-399: The king of Poland and grand duke of Lithuania. The prospects of changing allegiance in favor of the allied Kingdom of Poland and Grand Duchy of Lithuania caused a major commotion among the commoners. Janet Martin and Gail Lenhoff have recently argued that Boretskaya was scapegoated, probably by Archbishop Feofil ( r.  1470–1480 ) in order to shift the blame from him for his betrayal of

13050-544: The land belonging to Novgorod. Novgorod Republic ( Russian : Новгородская республика , romanized :  Novgorodskaya respublika ) itself is a much later term, although the polity was described as a republic as early as in the beginning of the 16th century. Soviet historians frequently used the terms Novgorod Feudal Republic and Novgorod Boyar Republic . The area of Novgorod was populated by various East Slavic tribes that were constantly at war with one another for supremacy. However, these tribes came together during

13195-406: The late 10th century until its formal annexation in 1478, the princes of Novgorod were dismissed and invited only about half the time, and the vast majority of these cases occurred between 1095 and 1293, and not consistently so during that period. That is, the office was elective for perhaps two centuries and even then it was not always elective. Even during this period, the nadir of princely power in

13340-508: The late 16th century peasants could leave their land in the weeks preceding and coming after George's Day in Autumn . Marxist scholars such as Aleksandr Khoroshev often spoke of a class struggle in Novgorod. There were some 80 major uprisings in the republic, which often turned into armed rebellions. The most notable among these took place in 1136, 1207, 1228–1229, 1270, 1418, and 1446–1447. The extent to which these were based on "class struggle"

13485-559: The law-courts of the archbishop of Novgorod would only be run by representatives chosen by the Pskovites. However, the archbishop of Novgorod continued to head the church in Pskov and kept the title of archbishop of Novgorod the Great and Pskov until 1589. As Moscow grew in strength, however, the Muscovite princes became a serious threat to Novgorod. Ivan I , Simeon , and other princes sought to limit Novgorod's independence. In 1397,

13630-402: The local elites, the boyars , took control of the city and the offices of posadnik and tysyatsky became elective. The veche (public assembly) played a not insignificant role in public life, although the precise makeup of the veche and its powers is uncertain and still contested among historians. The posadnik, tysiatsky, and even the local bishop or archbishop (after 1165) were elected at

13775-423: The main profit of the shift. In spite of unfavorable natural conditions, Novgorod's rural population was dependent upon agriculture and stock-rearing, while hunting and fishing were also important. The agricultural basis was also insecure, as the land passed almost fully into the hands of ruling boyars and clergy, with only a small area belonging to merchants. The peasants of Novgorod also paid dues to their lords in

13920-409: The market and exported to other Russian cities or abroad. The real wealth of Novgorod, however, came from the fur trade. Hanseatic merchants were particularly attracted to the Russian trade due to its vast resources of furs and beeswax, with Novgorod being the leading supplier of furs. The city was the main entrepôt for trade between Rus' and northwestern Europe as it was located at the eastern end of

14065-555: The metayage, monetary payments also gained significant importance by the second half of the 15th century. Some scholars argue that the feudal lords tried to legally tie down the peasants to their land. Certain categories of feudally dependent peasants, such as davniye lyudi (давние люди), polovniki (половники), poruchniki (поручники), and dolzhniki (должники), were deprived of the right to leave their masters. The boyars and monasteries also tried to restrict other categories of peasants from switching their feudal lords. However, until

14210-483: The more fanciful cartographers, tended to leave the region blank, with only fragments of known coastline sketched in. This lack of knowledge of what lay north of the shifting barrier of ice gave rise to a number of conjectures. In England and other European nations, the myth of an " Open Polar Sea " was persistent. John Barrow , longtime Second Secretary of the British Admiralty , promoted exploration of

14355-551: The next century and half, were able to invite in and dismiss a number of princes. However, these invitations or dismissals were often based on who was the dominant prince in Rus' at the time, and not on any independent thinking on the part of Novgorod. Rostov-Suzdal comprised the territory of the important Oka region and lands along the vital Sheksna River. This river lay in the Northern Volga tributary region. Whoever controlled

14500-497: The north polar regions remained largely unexplored and their geography conjectural. Pytheas of Massilia recorded an account of a journey northward in 325 BC, to a land he called " Eschate Thule ", where the Sun only set for three hours each day and the water was replaced by a congealed substance "on which one can neither walk nor sail". He was probably describing loose sea ice known today as " growlers " or "bergy bits"; his "Thule"

14645-400: The north pole was made in 1958 by the submarine USS Nautilus , and the first surface nautical transit occurred in 1977 by the icebreaker NS Arktika . Since 1937, Soviet and Russian manned drifting ice stations have extensively monitored the Arctic Ocean. Scientific settlements were established on the drift ice and carried thousands of kilometres by ice floes . In World War II ,

14790-585: The northern rivers that flowed into the Arctic, there are chronicles which mention that one expedition reached the Pechora River in 1032, and trading was established as early as 1096 with the Yugra tribes. The Chronicle mentions Novgorodians traveling "beyond the portage" as early as 1079. They also traveled to Pomorye, the "summer [southern] coast" of the "Cold [White] Sea" in search of furs as well as fish and salt. Historian George Lantzeff remarked that "in

14935-423: The number of recruits depended on the level of danger faced by Novgorod. The professional formations included the retinues of the archbishop and prominent boyars , as well as the garrisons of fortresses. Firearms were first mentioned in 1394, and in the 15th century, fortress artillery was used, and cannons were installed on ships. During the era of Kievan Rus' , Novgorod was a trade hub at the northern end of both

15080-578: The pack ice. Icebergs pose a hazard to ships, of which the Titanic is one of the most famous. The ocean is virtually icelocked from October to June, and the superstructure of ships are subject to icing from October to May. Before the advent of modern icebreakers, ships sailing the Arctic Ocean risked being trapped or crushed by sea ice (although the Baychimo drifted through the Arctic Ocean untended for decades despite these hazards). The Arctic Ocean

15225-463: The political system of Novgorod as a "feudal republic", placing it within the Marxist historiographic periodization ( slavery – feudalism – capitalism – socialism – communism ). Many scholars today, however, question whether Russia ever really had a feudal political system parallel to that of the medieval West. Historians have also described Novgorod's political system as an oligarchy due to

15370-595: The prince's power was gradually restricted, while the archbishop of Novgorod increasingly played the role of head of state, particularly during times of feuds. Just before 1300, a series of reforms further curtailed the prince's powers within the local administration while those of the archbishop rose. The Council of Lords ( Russian : Совет господ , romanized :  Sovet gospod ) was also formed, and boyar families from each district were represented, typically by former posadniki , with each posadnik beginning to hold office for only one year. As feuds continued to grow,

15515-595: The prince. From 1230 to 1478, the Grand Prince of Vladimir was either himself the Prince of Novgorod, or the patron of the Prince of Novgorod. There was fierce competition between the princes of Tver , Moscow , and Nizhny Novgorod-Suzdal for the title of Grand Prince of Vladimir , after 1400 increasingly granted by yarlik (patent) of the khan of the Golden Horde by winning his favour, which eventually

15660-416: The princes of Novgorod, invited by Novgorodians from neighboring states, even though their power waned in the 13th and early 14th centuries. It is unclear if the archbishop of Novgorod was the true head of state or chief executive of the Novgorod Republic, but in any case, he remained an important town official. In addition to overseeing the church in Novgorod, he headed embassies, oversaw certain court cases of

15805-433: The products of agriculture, fishing, forestry, and stock-rearing. Foreign coins and silver were used as a currency before Novgorod started minting its own novgorodka coins in 1420. More than half of all privately owned lands in Novgorod had been concentrated in the hands of some 30–40 noble boyar families by the 14th and 15th centuries. These vast estates served as material resources, which secured political supremacy of

15950-590: The region from 1818 to 1845 in search of this. In the United States in the 1850s and 1860s, the explorers Elisha Kane and Isaac Israel Hayes both claimed to have seen part of this elusive body of water. Even quite late in the century, the eminent authority Matthew Fontaine Maury included a description of the Open Polar Sea in his textbook The Physical Geography of the Sea (1883). Nevertheless, as all

16095-526: The reign of Yury . In part, Tver's proximity (the Tver principality was contiguous with Novgorod Land) threatened Novgorod. It was feared that a Tverian prince would annex Novgorod's territory, and thus weaken the republic. At the time, though, Moscow did not border Novgorod, and since the Muscovite princes were further afield, they were more acceptable as princes of Novgorod. They could come to Novgorod's aid when needed but would be too far away to meddle too much in

16240-624: The republic's affairs. The city of Pskov , initially part of Novgorod Land, became de facto independent as early as the 13th century after opening a trading post for merchants of the Hanseatic League . Several princes such as Vsevolod Mstislavich ( d.  1138 ) and Dovmont ( d.  1299 ) reigned in Pskov without any deference to, or consultation with, the prince or other officials in Novgorod. Pskov won its formal independence in August 1348 after Magnus IV of Sweden captured

16385-403: The rest for his allies. The formal annexation of Novgorod marked a major step in the unification of Russia around Moscow, with Ivan III later adopting the title of sovereign of all Russia . The Novgorod Chronicle which had been critical of Ivan III before the fall of Novgorod thus described the conquest in its aftermath, justifying it on the grounds of purported conversion of Novgorodians to

16530-520: The rest. It remains relatively stable because the salinity effect on density is bigger than the temperature effect. It is fed by the freshwater input of the big Siberian and Canadian rivers ( Ob , Yenisei , Lena , Mackenzie ), the water of which quasi floats on the saltier, denser, deeper ocean water. Between this lower salinity layer and the bulk of the ocean lies the so-called halocline , in which both salinity and temperature rise with increasing depth. Because of its relative isolation from other oceans,

16675-416: The river was able to block food supplies causing a famine in Novgorod. Perhaps due to these fears, Novgorod led a failed invasion of Suzdal in 1134. They tried again and succeeded in 1149. Alternatively, Novgorod, in a bid to appease Suzdal, accepted some Suzdalians as rulers of Novgorod. Despite these events, Suzdal still blocked off trade to Novgorod twice and intercepted Novgorod's tributes. In 1228, there

16820-663: The role of salinity in density. When water reaches the basin, it is pushed by strong winds into a large circular current called the Beaufort Gyre . Water in the Beaufort Gyre is far less saline than that of the Chukchi Sea due to inflow from large Canadian and Siberian rivers. The final defined water mass in the Arctic Ocean is called Arctic Surface Water and is found in the depth range of 150–200 m (490–660 ft). The most important feature of this water mass

16965-462: The sea that sink over the continental shelf into the western Arctic Ocean and create a halocline. This water is met by Greenland Sea Deep Water, which forms during the passage of winter storms. As temperatures cool dramatically in the winter, ice forms, and intense vertical convection allows the water to become dense enough to sink below the warm saline water below. Arctic Bottom Water is critically important because of its outflow, which contributes to

17110-467: The shelf region that begins as inflow from the Pacific passes through the narrow Bering Strait at an average rate of 0.8 Sverdrups and reaches the Chukchi Sea . During the winter, cold Alaskan winds blow over the Chukchi Sea, freezing the surface water and pushing this newly formed ice out to the Pacific. The speed of the ice drift is roughly 1–4 cm/s. This process leaves dense, salty waters in

17255-411: The size of Antarctica . The coastline is 45,390 km (28,200 mi) long. It is the only ocean smaller than Russia , which has a land area of 16,377,742 km (6,323,482 sq mi). The Arctic Ocean is surrounded by the land masses of Eurasia (Russia and Norway), North America ( Canada and the U.S. state of Alaska), Greenland, and Iceland . Note: Some parts of the areas listed in

17400-441: The so-called zhityi lyudi (житьи люди), who owned less land than the boyars, and unprivileged small votchina owners called svoyezemtsy (своеземцы, or private landowners). The most common form of labor exploitation – the system of metayage – was typical for the afore-mentioned categories of landowners. Their household economies were mostly serviced by slaves ( kholops ), whose number had been constantly decreasing. Along with

17545-426: The structure was again changed so that each district had its own posadnik , with the number of posadniki increasing to 24 in 1423, though this failed to achieve stability, and feuds continued until the last days of independence. The Novgorod Judicial Charter , inherited from the earlier Russkaya Pravda , served as the legal code of the Novgorod Republic from 1440. The latest version was supplemented in 1471 under

17690-478: The summer months. There is also evidence that the drift is associated with the phase of the Arctic Oscillation and Atlantic Multidecadal Oscillation . Much of the Arctic Ocean is covered by sea ice that varies in extent and thickness seasonally. The mean extent of the Arctic sea ice has been continuously decreasing in the last decades, declining at a rate of currently 12.85% per decade since 1980 from

17835-664: The summer, the SLP contrast is smaller, producing weaker winds. A final example of seasonal pressure system movement is the low pressure system that exists over the Nordic and Barents Seas. It is an extension of the Icelandic Low , which creates cyclonic ocean circulation in this area. The low shifts to centre over the North Pole in the summer. These variations in the Arctic all contribute to ice drift reaching its weakest point during

17980-632: The table are located in the Atlantic Ocean . Other consists of Gulfs , Straits , Channels and other parts without specific names and excludes Exclusive Economic Zones . The Arctic Ocean is connected to the Pacific Ocean by the Bering Strait and to the Atlantic Ocean through the Greenland Sea and Labrador Sea . (The Iceland Sea is sometimes considered part of the Greenland Sea, and sometimes separate.) The largest seas in

18125-562: The terms of the Treaty of Yazhelbitsy, which forbade Novgorod from conducting foreign affairs without grand princely approval. While the extent of Boretskaya's role in the Lithuanian party is probably exaggerated, Novgorod did indeed try to turn to the king of Poland. A draft treaty, allegedly found among the loot after the Battle of Shelon River, was drawn up between Casimir and the Novgorodians. The Muscovite authorities saw Novgorod's behavior as

18270-621: The territory of Novgorod. He lived from money given to him by the city. According to several ryads , the prince could not extradite or prosecute a Novgorodian outside of Novgorod Land. The princes had two residences, one on the Marketplace (called Yaroslav's Court ), and another in Rurikovo Gorodische (Рюриково городище) several miles south of the Trade Side of the city. The administrative division of Novgorod Republic

18415-405: The time, and Novgorod often chose the most powerful prince in Rus' as their prince. That usually meant that the prince in Kiev, Vladimir or Moscow (who retained the title of grand prince of Vladimir from about the 1320s onward, although there were several interruptions), either took the title himself or appointed his son or other relative to be prince of Novgorod. At times other princes, from Tver ,

18560-472: The title of the figurehead leader of the Novgorod Republic . The position was originally an appointed one until the late 11th or early 12th century, then became something of an elective one until the early 14th century, after which the grand prince of Vladimir (who was almost always the prince of Moscow ) was almost invariably the prince of Novgorod as well. The title originates sometime in

18705-475: The upper 100–150 m (330–490 ft) of ocean water cools to the freezing point for sea ice to form. In the winter, the relatively warm ocean water exerts a moderating influence, even when covered by ice. This is one reason why the Arctic does not experience the extreme temperatures seen on the Antarctic continent . There is considerable seasonal variation in how much pack ice of the Arctic ice pack covers

18850-522: The use of weights and measures in the marketplace, and through other means. Another important executive was the posadnik of Novgorod, who chaired the veche , co-chaired courts together with the prince, oversaw tax collection and managed current affairs of the city. Most of the prince's major decisions had to be approved by the posadnik. In the mid-14th century, instead of one posadnik, the veche began electing six. These six posadniks kept their status for their lifetimes, and each year elected among themselves

18995-521: The veche, and it is said the veche invited and dismissed the prince as well. List based on Michael C. Paul (2008). From 970 to 1088, the Grand Prince of Kiev was the patron of the Prince of Novgorod. From 1088 to 1230, control over Novgorod was contested between various princely houses, and between them and the city itself. In 1136, the citizenry of Novgorod established the Novgorod Republic , and henceforth – in theory, though not always in practice – elected and dismissed its city officials, including

19140-466: The veche. Tradespeople and craftsmen also participated in the political affairs of Novgorod. Traditional scholarship argues that they were organized into five kontsy ("ends" in Russian) – i.e., the boroughs of the city they lived in; each end was then organized by the streets in which they lived. The ends and streets often bore names indicating that certain trades were concentrated in certain parts of

19285-493: The western Arctic indicate the Atlantic water heat remains isolated at intermediate depths even under the 'perfect storm' conditions of the Great Arctic Cyclone of 2012 . Waters originating in the Pacific and Atlantic both exit through the Fram Strait between Greenland and Svalbard Island, which is about 2,700 m (8,900 ft) deep and 350 km (220 mi) wide. This outflow is about 9 Sv. The width of

19430-628: The world; it holds large oil and gas reserves. The Chukchi shelf forms the border between Russian and the United States as stated in the USSR–USA Maritime Boundary Agreement . The whole area is subject to international territorial claims . The Chukchi Plateau extends from the Chukchi Sea Shelf. An underwater ridge , the Lomonosov Ridge , divides the deep sea North Polar Basin into two oceanic basins :

19575-547: The year. For example, the Beaufort High—an extension of the Siberian High system—is a pressure system that drives the anticyclonic motion of the Beaufort Gyre. During the summer, this area of high pressure is pushed out closer to its Siberian and Canadian sides. In addition, there is a sea level pressure (SLP) ridge over Greenland that drives strong northerly winds through the Fram Strait, facilitating ice export. In

19720-539: Was a failed Novgorodian campaign against the Tavastians in present-day southern Finland , as reported in the Novgorod First Chronicle (NPL). The Novgorodian troops were disaffected by prince Yaroslav Vsevolodovich , a quarrel broke out within the army and the troops refused to fight. In the same year, Yaroslav tried to militarily overrun the rebellious town of Pskov (possibly because its throne

19865-465: Was being wise, with cooperation with the Mongols being the only sensible option at the time which averted further tragedy. Tver , Moscow and Lithuania fought over control of Novgorod and its enormous wealth from the 14th century. Upon receiving the jarlig for grand prince of Vladimir in 1304, Mikhail Yaroslavich of Tver sent his governors to Novgorod . A series of disagreements with Mikhail pushed Novgorod towards closer ties with Moscow during

20010-470: Was considerable. The Lübeck company of Wittenborg exported between 200,000 and 500,000 Lübeck marks from Novgorod to Livonia in the 1350s. Anna Khoroshkevich assumed that exports increased throughout the 14th century and was at its height in the beginning of the 15th century, but by the second half of the century, Novgorod suffered from the effects of exhaustion of its resources with hunting grounds moving considerably further north and Muscovite merchants accruing

20155-415: Was dismissed by the Novgorodians, and that Novgorod could invite and dismiss its princes at will. In this way, the prince of Novgorod was no longer the "ruler" of Novgorod but became an elective or appointed official of the city-state. That being said, the traditional view of the prince being invited in or dismissed at will is an oversimplification of a long and complex history of the office. In fact, from

20300-489: Was in Novgorod, he paid two thousand grivny a year as tribute to Kiev, and another thousand was given to his garrison in Novgorod." The "Russian–Scandinavian cultural symbiosis" became prevalent following the establishment of the Rus' state. The Novgorodians were the first to reach the regions between the Arctic Ocean and Lake Onega . Even though there is no definitive account of the precise timing of their arrival at

20445-450: Was included in the title of the Russian monarch , which lasted until the abdication of Nicholas II of Russia in 1917. After Novgorod was formally annexed by Moscow in 1478, Ivan assumed the title of sovereign of all Russia . From the early 12th century, the prince's power in the Novgorod Republic was more nominal. Imperial and Soviet-era scholars often argued that the office was ineffectual after 1136, when Prince Vsevolod Mstislavich

20590-408: Was originally the military commander, and served the interests of the common people. Novgorodian nobles known as boyars dominated the veche , and the offices of posadnik and tysyatsky remained in the hands of boyar families. The boyars also gave funding to the ushkuyniki , who contributed to the expansion of Novgorod's trade and colonies in the north of European Russia . By the 14th century,

20735-674: Was probably Norway , though the Faroe Islands or Shetland have also been suggested. Early cartographers were unsure whether to draw the region around the North Pole as land (as in Johannes Ruysch 's map of 1507, or Gerardus Mercator 's map of 1595) or water (as with Martin Waldseemüller 's world map of 1507). The fervent desire of European merchants for a northern passage, the Northern Sea Route or

20880-421: Was unique was that no princely dynasty managed to establish itself within the city and take permanent control over the city.
