From the mid-13th century onwards Scottish monarchs increasingly sought to take control of the islands surrounding their seas. The process was begun in earnest by Alexander II and was continued by his successor Alexander III . This strategy eventually led to an invasion of Scotland by Haakon IV Haakonsson , King of Norway. His fleet assembled in Bressay Sound before sailing for Scotland. After
5217-622: The 13th century the Hanseatic League , though centred on the Baltic Sea , started to control most of the trade through important members and outposts on the North Sea. The League lost its dominance in the 16th century, as neighbouring states took control of former Hanseatic cities and outposts. Their internal conflict prevented effective cooperation and defence. As the League lost control of its maritime cities, new trade routes emerged that provided Europe with Asian, American, and African goods. The 17th century Dutch Golden Age saw Dutch maritime power at its zenith. Important overseas colonies,

7770-500: The Scottish crown for their territory on mainland Britain, which they held as the Mormaer of Caithness , but owed allegiance to the Norwegian crown for Orkney and Shetland. In 1194, when Harald Maddadsson was Earl of Orkney, a rebellion broke out against King Sverre Sigurdsson of Norway. The Eyjarskeggjar ("Island Beardies") sailed for Norway but were beaten in the Battle of Florvåg near Bergen . After his victory, King Sverre placed Shetland under direct Norwegian rule in 1195 as
7881-400: The Scottish mainland. There are also Old Red Sandstone deposits and granite intrusions. The most distinctive feature is the ophiolite in Unst and Fetlar which is a remnant of the Iapetus Ocean floor made up of ultrabasic peridotite and gabbro . Much of Shetland's economy depends on the oil-bearing sediments in the surrounding seas. Geological evidence shows that in around 6100 BC
7992-539: The Stout during a visit to Orkney and said, "I order you and all your subjects to be baptised. If you refuse, I'll have you killed on the spot and I swear I will ravage every island with fire and steel". Unsurprisingly, Sigurd agreed, and the islands became Christian at a stroke. The Scottish crown claimed the overlordship of the Caithness and Sutherland area from Norway in 1098. The jarls thereafter owed allegiance to
8103-600: The Viking Health Study are severely flawed as they account for only a tiny fraction of the population. Vikings then used the islands as a base for pirate expeditions to Norway and the coasts of mainland Scotland. In response, Norwegian king Harald Hårfagre ("Harald Fair Hair") annexed the Northern Isles (comprising Orkney and Shetland) in 875. Rognvald Eysteinsson received the Earldom of Orkney , which then included Shetland, from Harald as reparation for
8214-527: The Western Isles, their inhabitants, most of whom appear to have been Pictish in culture and speech at this time, are likely to have regarded Bridei as a fairly distant presence". In 2011, the collective site, " The Crucible of Iron Age Shetland ", including Broch of Mousa, Old Scatness and Jarlshof, joined the UKs "Tentative List" of World Heritage Sites . The expanding population of Scandinavia led to
8325-649: The border between the Atlantic Ocean to the west and the North Sea to the east. Their total area is 1,467 km (566 sq mi), and the population totalled 23,020 in 2022. The islands comprise the Shetland constituency of the Scottish Parliament . Shetland forms one of the 32 council areas of Scotland; the local authority is the Shetland Islands Council . The islands' administrative centre, largest settlement and only burgh
8436-611: The coasts of the Netherlands, Belgium, Germany, and Denmark and low-lying areas of eastern England particularly around The Wash and Fens . Storm surges are caused by changes in barometric pressure combined with strong wind created wave action . The first recorded storm tide flood was the Julianenflut , on 17 February 1164. In its wake, the Jadebusen , (a bay on the coast of Germany), began to form. A storm tide in 1228
8547-471: The death of his son in battle in Scotland, and then passed the earldom on to his brother Sigurd the Mighty . Sigurd went on to conquer further territory; by the time of his death in 892, the earldom of Orkney stretched from Shetland down to Caithness and Sutherland on mainland Britain. The islands converted to Christianity in the late 10th century. King Olaf I Tryggvasson summoned the jarl Sigurd
8658-586: The decline. For example, a resident orca pod was lost in the 1960s, presumably due to the peak in PCB pollution in this time period. The OSPAR commission manages the OSPAR convention to counteract the harmful effects of human activity on wildlife in the North Sea, preserve endangered species , and provide environmental protection. All North Sea border states are signatories of the MARPOL 73/78 Accords, which preserve
8769-555: The energy of the incoming sea, so that the dike itself does not receive the full impact. Dikes that lie directly on the sea are especially reinforced. The dikes have, over the years, been repeatedly raised, sometimes up to 9 metres (30 ft) and have been made flatter to better reduce wave erosion. Where the dunes are sufficient to protect the land behind them from the sea, these dunes are planted with beach grass ( Ammophila arenaria ) to protect them from erosion by wind, water, and foot traffic. Storm surges threaten, in particular,
8880-426: The family of his bride, Margaret of Denmark . After Scotland and England united in 1707 to form the Kingdom of Great Britain , trade between Shetland and continental Northern Europe decreased. The discovery of North Sea oil in the 1970s significantly boosted Shetland's economy, employment and public-sector revenues. Fishing has always been an important part of the islands' economy. The local way of life reflects
8991-572: The finest fishing location of the North Sea. The Long Forties and the Broad Fourteens are large areas with roughly uniform depth in fathoms (forty fathoms and fourteen fathoms or 73 and 26 m or 240 and 85 ft deep, respectively). These great banks and others make the North Sea particularly hazardous to navigate, which has been alleviated by the implementation of satellite navigation systems . The Devil's Hole lies 320 kilometres (200 mi) east of Dundee , Scotland. The feature
9102-704: The following year the Northern Isles were directly absorbed by the Crown of Scotland, an action confirmed by the Parliament of Scotland in 1472. Nonetheless, Shetland's connection with Norway has proved to be enduring. From the early 15th century onward Shetlanders sold their goods through the Hanseatic League of German merchantmen. The Hansa would buy shiploads of salted fish, wool and butter, and import salt , cloth , beer and other goods. The late 16th century and early 17th century were dominated by
9213-491: The greatest concentration of services and facilities. They are the three settlements in the table above, plus Aith , Baltasound , Mid Yell , Sandwick , and Symbister . List of islands by largest population: Due to the practice, dating to at least the early Neolithic , of building in stone on virtually treeless islands, Shetland is extremely rich in physical remains of the prehistoric eras and there are over 5,000 archaeological sites all told. A midden site at West Voe on
9324-433: The group is known as Mainland . The next largest are Yell , Unst , and Fetlar , which lie to the north, and Bressay and Whalsay , which lie to the east. East and West Burra , Muckle Roe , Papa Stour , Trondra , and Vaila are smaller islands to the west of Mainland. The other inhabited islands are Foula 17 mi (28 km) west of Walls , Fair Isle 24 mi (38 km) south-west of Sumburgh Head , and
9435-531: The highest variability where there is fresh water inflow, such as at the Rhine and Elbe estuaries, the Baltic Sea exit and along the coast of Norway. The main pattern to the flow of water in the North Sea is an anti-clockwise rotation along the edges. The North Sea is an arm of the Atlantic Ocean receiving the majority of ocean current from the northwest opening, and a lesser portion of warm current from
9546-414: The influence of the despotic Robert Stewart , Earl of Orkney, who was granted the islands by his half-sister Mary Queen of Scots , and his son Patrick . The latter commenced the building of Scalloway Castle , but after his imprisonment in 1609, the Crown annexed Orkney and Shetland again until 1643, when Charles I granted them to William Douglas, 7th Earl of Morton . These rights were held on and off by
9657-471: The inhabitants of the islands was replaced by the Shetland dialect of Scots and Hjaltland became Ȝetland . The initial letter is the Middle Scots letter, yogh , the pronunciation of which is almost identical to the original Norn sound, /hj/ . When the use of the letter yogh was discontinued, it was often replaced by the similar-looking letter z (which at the time was usually rendered with
9768-555: The islands' latitude , on clear winter nights the northern lights can sometimes be seen in the sky, while in summer there is almost perpetual daylight , a state of affairs known locally as the "simmer dim". Annual bright sunshine averages 1110 hours, and overcast days are common. There are only three settlements with a population over 500, being the town of Lerwick and the villages of Scalloway and Brae. 6,760 1,170 750 For town planning purposes, Shetland Islands Council has identified eight 'Tier 1' settlements, being areas with
9879-622: The land be built"). The phrase is of Old Norse origin, is mentioned in Njáls saga , and was likely borrowed from provincial Norwegian laws such as the Frostathing Law . The name Shetland may derive from the Old Norse words hjalt (' hilt '), and land ('land'), the popular and traditional claim. Another possibility is that the first syllable is derived from the name of an ancient Celtic tribe . Andrew Jennings has suggested
9990-505: The local fauna and flora , including a number of important seabird nesting sites. The Shetland pony and Shetland Sheepdog are two well-known Shetland animal breeds . Other animals with local breeds include the Shetland sheep , cow , goose , and duck . The Shetland pig, or grice , has been extinct since about 1930. The islands' motto, which appears on the Council's coat of arms , is " Með lögum skal land byggja " ("By law shall
10101-489: The marine environment by preventing pollution from ships. Germany, Denmark, and the Netherlands also have a trilateral agreement for the protection of the Wadden Sea , or mudflats , which run along the coasts of the three countries on the southern edge of the North Sea. The North Sea has had various names throughout history. One of the earliest recorded names was Septentrionalis Oceanus , or "Northern Ocean", which
10212-681: The names of the county of Caithness and in the Scottish Gaelic name for Sutherland , Cataibh , which means "among the Cats". The oldest known version of the modern name Shetland is Hetland ; this may represent "Catland", the Germanic language softening the C- to H- according to Grimm's law (also coinciding with Jennings' hypothesis for the early sound shift necessary for descent from *kalid- to *halit- , from Caledones ). It occurs in
10323-500: The prevailing flood levels. It was only around the beginning of the High Middle Ages , in 1200 AD, that inhabitants began to connect single ring dikes into a dike line along the entire coast, thereby turning amphibious regions between the land and the sea into permanent solid ground. The modern form of the dikes supplemented by overflow and lateral diversion channels, began to appear in the 17th and 18th centuries, built in
10434-415: The royal house in the islands declined. In 1469, Shetland was pledged by Christian I , in his capacity as King of Norway, as security against the payment of the dowry of his daughter Margaret , betrothed to James III of Scotland . As the money was never paid, the connection with the Crown of Scotland became permanent. In 1470, William Sinclair, 1st Earl of Caithness , ceded his title to James III, and
10545-469: The sea creating deep fjords and archipelagos . South of Stavanger, the coast softens, the islands become fewer. The eastern Scottish coast is similar, though less severe than Norway. From north east of England , the cliffs become lower and are composed of less resistant moraine , which erodes more easily, so that the coasts have more rounded contours. In the Netherlands, Belgium and in East Anglia
10656-423: The sea, and Leif Larsen , the most highly decorated allied naval officer of the war, made 52 of them. Several RAF airfields and sites were also established at Sullom Voe and several lighthouses suffered enemy air attacks. Oil reserves discovered in the later 20th century in the seas both east and west of Shetland have provided a much-needed alternative source of income for the islands. The East Shetland Basin
10767-413: The shores of the sea clogging harbours and inlets and has become a nuisance. Due to the heavy human populations and high level of industrialization along its shores, the wildlife of the North Sea has suffered from pollution, overhunting, and overfishing. Flamingos and pelicans were once found along the southern shores of the North Sea, but became extinct over the second millennium. Walruses frequented
10878-471: The smaller opening at the English Channel. These tidal currents leave along the Norwegian coast. Surface and deep water currents may move in different directions. Low salinity surface coastal waters move offshore, and deeper, denser high salinity waters move inshore. The North Sea located on the continental shelf has different waves from those in deep ocean water. The wave speeds are diminished and
10989-497: The south coast of Mainland, dated to 4320–4030 BC, has provided the first evidence of Mesolithic human activity in Shetland. The same site provides dates for early Neolithic activity and finds at Scord of Brouster in Walls have been dated to 3400 BC. "Shetland knives" are stone tools that date from this period made from felsite from Northmavine . Pottery shards found at the important site of Jarlshof also indicate that there
11100-408: The south of Muckle Roe), and during a single year from March 1917 more than 4,500 ships sailed from Lerwick as part of an escorted convoy system. In total, Shetland lost more than 500 men, a higher proportion than any other part of Britain, and there were further waves of emigration in the 1920s and 1930s. During World War II , a Norwegian naval unit nicknamed the " Shetland Bus " was established by
11211-557: The south, the coast consists mainly of sandy beaches, estuaries of long rivers and wide mudflats . Due to the dense population, heavy industrialisation , and intense use of the sea and the area surrounding it, various environmental issues affect the sea's ecosystems. Adverse environmental issues – commonly including overfishing , industrial and agricultural runoff , dredging , and dumping, among others – have led to several efforts to prevent degradation and to safeguard long-term economic benefits. The North Sea
11322-680: The stalemate of the Battle of Largs , Haakon retreated to Orkney, where he died in December 1263, entertained on his deathbed by recitations of the sagas. His death halted any further Norwegian expansion in Scotland and following this ill-fated expedition, the Hebrides and Mann were yielded to the Kingdom of Scotland as a result of the 1266 Treaty of Perth , although the Scots recognised continuing Norwegian sovereignty over Orkney and Shetland. In
11433-888: The uplands of the Fennoscandian Shield and the British Isles. This precursor of the current North Sea has grown and shrunk with the rise and fall of the eustatic sea level during geologic time. Sometimes it was connected with other shallow seas, such as the sea above the Paris Basin to the south-west, the Paratethys Sea to the south-east, or the Tethys Ocean to the south. During the Late Cretaceous, about 85 million years ago , all of modern mainland Europe except for Scandinavia
11544-568: The war on the side of Japan. During the First World War , Great Britain's Grand Fleet and Germany's Kaiserliche Marine faced each other in the North Sea, which became the main theatre of the war for surface action. Britain's larger fleet and North Sea Mine Barrage were able to establish an effective blockade for most of the war, which restricted the Central Powers ' access to many crucial resources. Major battles included
11655-649: The war, hundreds of thousands of tons of chemical weapons were disposed of by being dumped in the North Sea. Shetland Islands Shetland , also called the Shetland Islands , is an archipelago in Scotland lying between Orkney , the Faroe Islands , and Norway . It is the northernmost region of the United Kingdom . The islands lie about 50 miles (80 kilometres) to the northeast of Orkney, 110 mi (170 km) from mainland Scotland and 140 mi (220 km) west of Norway. They form part of
11766-406: The wave amplitudes are increased. In the North Sea there are two amphidromic systems and a third incomplete amphidromic system. In the North Sea the average tide difference in wave amplitude is between zero and eight metres (26 ft). The Kelvin tide of the Atlantic Ocean is a semidiurnal wave that travels northward. Some of the energy from this wave travels through the English Channel into
11877-431: The wettest months, averaging 5.6 to 5.9 inches of precipitation, mostly rain. Snowfall is usually confined to the period November to February, and snow seldom lies on the ground for more than a day. Relatively less rain falls from April to July, although on average, no month receives less than 50 mm (2.0 in). Fog is common during summer due to the cooling effect of the sea on mild southerly airflows. Because of
11988-535: Was Neolithic activity there although the main settlement dates from the Bronze Age . This includes a smithy , a cluster of wheelhouses and a later broch. The site has provided evidence of habitation during various phases right up until Viking times. Heel-shaped cairns , are a style of chambered cairn unique to Shetland, with a particularly large example in Vementry . Numerous brochs were erected during
12099-595: Was a scattering of islands. By the Early Oligocene , 34 to 28 million years ago , the emergence of Western and Central Europe had almost completely separated the North Sea from the Tethys Ocean, which gradually shrank to become the Mediterranean as Southern Europe and South West Asia became dry land. The North Sea was cut off from the English Channel by a narrow land bridge until that
12210-566: Was breached by at least two catastrophic floods between 450,000 and 180,000 years ago. Since the start of the Quaternary period about 2.6 million years ago , the eustatic sea level has fallen during each glacial period and then risen again. Every time the ice sheet reached its greatest extent, the North Sea became almost completely dry, the dry landmass being known as Doggerland , whose northern regions were themselves known to have been glaciated. The present-day coastline formed after
12321-632: Was cited by Pliny . He also noted that the Cimbri called it Morimarusa – "Dead Sea". The name "North Sea" probably came into English, however, via the Dutch Noordzee , who named it thus either in contrast with the Zuiderzee ("South Sea"), located south of Frisia , or because the sea is generally to the north of the Netherlands. Before the adoption of "North Sea", the names used in English were "German Sea" or "German Ocean", referred to as
