222-537: A few days downriver by ascending another river to the north. De Orellana took about 57 men, the boat, and some canoes and left Pizarro's troops on 26 December 1541. However, De Orellana missed the confluence (probably with the Aguarico ) where he was searching supplies for his men. By the time he and his men reached another village, many of them were sick from hunger and eating "noxious plants", and near death. Seven men died in that village. His men threatened to mutiny if

296-708: A few hills, and the river enters the enormous Amazon rainforest . Although the Ucayali–Marañón confluence is the point at which most geographers place the beginning of the Amazon River proper, in Brazil the river is known at this point as the Solimões das Águas . The river systems and flood plains in Brazil, Peru, Ecuador, Colombia, and Venezuela, whose waters drain into the Solimões and its tributaries, are called

370-469: A fourth found it profitable to navigate some of the smaller streams. In that same period, the Amazonas Company was increasing its fleet. Meanwhile, private individuals were building and running small steam craft of their own on the main river as well as on many of its tributaries. On 31 July 1867, the government of Brazil, constantly pressed by the maritime powers and by the countries encircling

444-491: A population of 1.9 million people in 2014, Manaus is the largest city on the Amazon. Manaus alone makes up approximately 50% of the population of the largest Brazilian state of Amazonas . The racial makeup of the city is 64% pardo (mulatto and mestizo) and 32% white . Although the Amazon river remains undammed, around 412 dams are in operation on the Amazon's tributary rivers. Of these 412 dams, 151 are constructed over six of

518-485: A second line to make six round voyages a year between Manaus and Tabatinga, and a third, two trips a month between Pará and Cametá. This was the first step in opening up the vast interior. The success of the venture called attention to the opportunities for economic exploitation of the Amazon, and a second company soon opened commerce on the Madeira, Purús, and Negro; a third established a line between Pará and Manaus, and

592-850: Is the largest river by discharge volume of water in the world, and the longest or second-longest river system in the world , a title which is disputed with the Nile . The headwaters of the Apurímac River on Nevado Mismi had been considered for nearly a century the Amazon basin 's most distant source until a 2014 study found it to be the headwaters of the Mantaro River on the Cordillera Rumi Cruz in Peru . The Mantaro and Apurímac rivers join, and with other tributaries form

666-477: Is the largest drainage basin in the world, with an area of approximately 7,000,000 km (2,700,000 sq mi). The portion of the river's drainage basin in Brazil alone is larger than any other river's basin. The Amazon enters Brazil with only one-fifth of the flow it finally discharges into the Atlantic Ocean , yet already has a greater flow at this point than the discharge of any other river in

740-466: Is the largest river branch one encounters when journeying upstream, and lies farther to the west than any other tributary of the Amazon. For most of the 18th–19th centuries and into the 20th century, the Marañón was generally considered the source of the Amazon. Early scientific, zoological, and botanical exploration of the Amazon River and basin took place from the 18th century through the first half of

814-712: The Amazon warriors , a tribe of women warriors related to Iranian Scythians and Sarmatians mentioned in Greek mythology . The word Amazon itself may be derived from the Iranian compound * ha-maz-an- "(one) fighting together" or ethnonym * ha-mazan- "warriors", a word attested indirectly through a derivation, a denominal verb in Hesychius of Alexandria 's gloss "ἁμαζακάραν· πολεμεῖν. Πέρσαι" (" hamazakaran : 'to make war' in Persian"), where it appears together with

Strabo , in his Geographica (1st century AD), mentions of the Medes , Persians, Bactrians and Sogdians of the Iranian Plateau and Transoxiana of antiquity: The name of Ariana is further extended to a part of Persia and of Media, as also to the Bactrians and Sogdians on the north; for these speak approximately the same language, with but slight variations. The Bactrian (a Middle Iranian language) inscription of Kanishka (the founder of

962-578: The Indo-Iranian root * kar- "make" (from which Sanskrit karma is also derived). Other scholars claim that the name is derived from the Tupi word amassona , meaning "boat destroyer". Recent geological studies suggest that for millions of years the Amazon River used to flow in the opposite direction - from east to west. Eventually the Andes Mountains formed, blocking its flow to

1036-663: The Iranic peoples , are the collective ethno-linguistic groups who are identified chiefly by their native usage of any of the Iranian languages , which are a branch of the Indo-Iranian languages within the Indo-European language family . The Proto-Iranians are believed to have emerged as a separate branch of the Indo-Iranians in Central Asia around the mid-2nd millennium BC. At their peak of expansion in

1110-522: The Kushan Empire ) at Rabatak, which was discovered in 1993 in an unexcavated site in the Afghan province of Baghlan , clearly refers to this Eastern Iranian language as Arya . All this evidence shows that the name Arya was a collective definition, denoting peoples who were aware of belonging to the one ethnic stock, speaking a common language, and having a religious tradition that centered on

1184-519: The Pacific Ocean , and causing it to switch directions to its current mouth in the Atlantic Ocean . During what many archaeologists called the formative stage , Amazonian societies were deeply involved in the emergence of South America's highland agrarian systems. The trade with Andean civilizations in the terrains of the headwaters in the Andes formed an essential contribution to

1258-921: The Parthians , the Persians , the Sagartians , the Saka , the Sarmatians , the Scythians , the Sogdians , and likely the Cimmerians , among other Iranian-speaking peoples of West Asia , Central Asia, Eastern Europe , and the Eastern Steppe . In the 1st millennium AD, their area of settlement, which was mainly concentrated in the steppes and deserts of Eurasia , was significantly reduced due to

1332-788: The Río Apurímac . A 2014 study by Americans James Contos and Nicolas Tripcevich in Area , a peer-reviewed journal of the Royal Geographical Society , however, identifies the most distant source of the Amazon as actually being in the Río Mantaro drainage. A variety of methods were used to compare the lengths of the Mantaro river vs. the Apurímac river from their most distant source points to their confluence, showing

1406-802: The Sintashta culture and the subsequent Andronovo culture within the broader Andronovo horizon, and their homeland with an area of the Eurasian steppe that borders the Ural River on the west and the Tian Shan on the east. The Indo-Iranian migrations took place in two waves. The first wave consisted of the Indo-Aryan migration through the Bactria-Margiana Culture , also called "Bactria-Margiana Archaeological Complex," into

1480-707: The Ucayali River , which in turn meets the Marañón River upstream of Iquitos, Peru , forming what countries other than Brazil consider to be the main stem of the Amazon. Brazilians call this section the Solimões River above its confluence with the Rio Negro forming what Brazilians call the Amazon at the Meeting of Waters ( Portuguese : Encontro das Águas ) at Manaus , the largest city on

1554-1288: The Zazas . Their current distribution spreads across the Iranian Plateau ;– stretching from the Caucasus in the north to the Persian Gulf in the south and from eastern Anatolia in the west to western Xinjiang in the east – covering a region that is sometimes called Greater Iran , representing the extent of the Iranian-speaking peoples and the reach of their geopolitical and cultural influence. The term Iran derives directly from Middle Persian Ērān / AEran ( 𐭠𐭩𐭥𐭠𐭭 ) and Parthian Aryān . The Middle Iranian terms ērān and aryān are oblique plural forms of gentilic ēr- (in Middle Persian) and ary- (in Parthian), both deriving from Old Persian ariya- ( 𐎠𐎼𐎡𐎹 ), Avestan airiia- ( 𐬀𐬌𐬭𐬌𐬌𐬀 ) and Proto-Iranian *arya- . There have been many attempts to qualify

1628-568: The rubber boom it is estimated that diseases brought by immigrants, such as typhus and malaria , killed 40,000 native Amazonians. The first direct foreign trade with Manaus commenced around 1874. Local trade along the river was carried on by the English successors to the Amazonas Company—the Amazon Steam Navigation Company—as well as numerous small steamboats, belonging to companies and firms engaged in

1702-604: The upper Amazon basin, especially Peru, decreed the opening of the Amazon to all countries, but they limited this to certain defined points: Tabatinga – on the Amazon; Cametá – on the Tocantins; Santarém – on the Tapajós; Borba – on the Madeira, and Manaus – on the Rio Negro. The Brazilian decree took effect on 7 September 1867. Thanks in part to the mercantile development associated with steamboat navigation coupled with

1776-671: The "Companhia de Navegação e Comércio do Amazonas" in Rio de Janeiro in 1852; in the following year it commenced operations with four small steamers, the Monarca ('Monarch'), the Cametá , the Marajó and the Rio Negro . At first, navigation was principally confined to the main river; and even in 1857 a modification of the government contract only obliged the company to a monthly service between Pará and Manaus, with steamers of 200 tons cargo capacity,

1850-587: The "Upper Amazon". The Amazon proper runs mostly through Brazil and Peru, and is part of the border between Colombia and Peru. It has a series of major tributaries in Colombia , Ecuador and Peru , some of which flow into the Marañón and Ucayali , and others directly into the Amazon proper. These include rivers Putumayo , Caquetá , Vaupés , Guainía , Morona , Pastaza , Nucuray, Urituyacu, Chambira , Tigre , Nanay , Napo , and Huallaga . At some points,

1924-623: The "land without people" in the Amazon Basin. This was done in conjunction with infrastructure projects mainly the Trans-Amazonian Highway ( Transamazônica ). The Trans-Amazonian Highway's three pioneering highways were completed within ten years but never fulfilled their promise. Large portions of the Trans-Amazonian and its accessory roads, such as BR-317 (Manaus- Porto Velho ), are derelict and impassable in

1998-575: The 19th century. The Cabanagem revolt (1835–1840) was directed against the white ruling class. It is estimated that from 30% to 40% of the population of Grão-Pará , estimated at 100,000 people, died. The population of the Brazilian portion of the Amazon basin in 1850 was perhaps 300,000, of whom about 175,000 were Europeans and 25,000 were slaves. The Brazilian Amazon's principal commercial city, Pará (now Belém), had from 10,000 to 12,000 inhabitants, including slaves. The town of Manáos, now Manaus, at

2072-538: The 20th century. Wary of foreign exploitation of the nation's resources, Brazilian governments in the 1940s set out to develop the interior, away from the seaboard where foreigners owned large tracts of land. The original architect of this expansion was president Getúlio Vargas , with the demand for rubber from the Allied forces in World War II providing funding for the drive. In the 1960s, economic exploitation of

2146-413: The Amazon River." In March 1500, Spanish conquistador Vicente Yáñez Pinzón was the first documented European to sail up the Amazon River. Pinzón called the stream Río Santa María del Mar Dulce , later shortened to Mar Dulce , literally, sweet sea , because of its freshwater pushing out into the ocean. Another Spanish explorer, Francisco de Orellana , was the first European to travel from

2220-582: The Amazon basin was seen as a way to fuel the "economic miracle" occurring at the time. This resulted in the development of "Operation Amazon", an economic development project that brought large-scale agriculture and ranching to Amazonia. This was done through a combination of credit and fiscal incentives. However, in the 1970s the government took a new approach with the National Integration Program (PIN). A large-scale colonization program saw families from northeastern Brazil relocated to

2294-416: The Amazon in 1541, more than 3 million indigenous people lived around the Amazon. These pre-Columbian settlements created highly developed civilizations. For instance, pre-Columbian indigenous people on the island of Marajó may have developed social stratification and supported a population of 100,000 people. To achieve this level of development, the indigenous inhabitants of the Amazon rainforest altered

2368-513: The Amazon river is about 80 km longer than previously thought. Contos continued downstream to the ocean and finished the first complete descent of the Amazon river from its newly identified source (finishing November 2012), a journey repeated by two groups after the news spread. After about 700 km (430 mi), the Apurímac then joins Río Mantaro to form the Ene, which joins the Perene to form

2442-403: The Amazon will harm its biodiversity in the same way by "blocking fish-spawning runs, reducing the flows of vital oil nutrients and clearing forests". Damming the Amazon River could potentially bring about the "end of free flowing rivers" and contribute to an " ecosystem collapse " that will cause major social and environmental problems. The most distant source of the Amazon was thought to be in

2516-409: The Amazon, investigating many of its tributaries, including the Rio Negro, and covering a distance of over 10,000 km (6,200 mi). In what is currently in Brazil, Ecuador, Bolivia, Colombia, Peru, and Venezuela, several colonial and religious settlements were established along the banks of primary rivers and tributaries for trade, slaving , and evangelization among the indigenous peoples of

2590-564: The Apurímac river drainage for nearly a century. Such studies continued to be published even as recently as 1996, 2001, 2007, and 2008, where various authors identified the snowcapped 5,597 m (18,363 ft) Nevado Mismi peak, located roughly 160 km (99 mi) west of Lake Titicaca and 700 km (430 mi) southeast of Lima , as the most distant source of the river. From that point, Quebrada Carhuasanta emerges from Nevado Mismi, joins Quebrada Apacheta and soon forms Río Lloqueta which becomes Río Hornillos and eventually joins

2664-785: The Greek sources. Herodotus , in his Histories , remarks about the Iranian Medes that "Medes were called anciently by all people Arians " (7.62). In Armenian sources, the Parthians, Medes and Persians are collectively referred to as Iranians . Eudemus of Rhodes (Dubitationes et Solutiones de Primis Principiis, in Platonis Parmenidem) refers to "the Magi and all those of Iranian ( áreion ) lineage". Diodorus Siculus (1.94.2) considers Zoroaster ( Zathraustēs ) as one of

2738-677: The Indo-Aryans who founded the Mitanni kingdom in northern Syria; ( c.  1500  – c.  1300 BC ) the other group were the Vedic people. Christopher I. Beckwith suggests that the Wusun , an Indo-European Caucasian people of Inner Asia in antiquity , were also of Indo-Aryan origin. The second wave is interpreted as the Iranian wave, and took place in the third stage of

2812-442: The Indo-European migrations from 800 BC onwards. The Sintashta culture, also known as the Sintashta–Petrovka culture or Sintashta–Arkaim culture, is a Bronze Age archaeological culture of the northern Eurasian steppe on the borders of Eastern Europe and Central Asia , dated to the period 2100–1800 BC . It is probably the archaeological manifestation of the Indo-Iranian language group. The Sintashta culture emerged from

2886-411: The Levant, founding the Mittani kingdom ; and a migration south-eastward of the Vedic people, over the Hindu Kush into northern India. The Indo-Aryans split off around 1800–1600 BC from the Iranians, whereafter they were defeated and split into two groups by the Iranians, who dominated the Central Eurasian steppe zone and "chased [the Indo-Aryans] to the extremities of Central Eurasia." One group were

2960-483: The Portuguese portion of the Amazon basin has remained a land largely undeveloped by agriculture and occupied by indigenous people who survived the arrival of European diseases. Four centuries after the European discovery of the Amazon river, the total cultivated area in its basin was probably less than 65 km (25 sq mi), excluding the limited and crudely cultivated areas among the mountains at its extreme headwaters. This situation changed dramatically during

3034-439: The Tambo, which joins the Urubamba River to form the Ucayali. After the confluence of Apurímac and Ucayali, the river leaves Andean terrain and is surrounded by floodplain . From this point to the confluence of the Ucayali and the Marañón, some 1,600 km (990 mi), the forested banks are just above the water and are inundated long before the river attains its maximum flood stage. The low river banks are interrupted by only

3108-662: The command of Shapur I gives a more clear description. The languages used are Parthian, Middle Persian, and Greek. In Greek inscription says "ego ... tou Arianon ethnous despotes eimi" , which translates to "I am the king of the kingdom ( nation ) of the Iranians". In Middle Persian, Shapur says "ērānšahr xwadāy hēm" and in Parthian he says "aryānšahr xwadāy ahēm" . The Avesta clearly uses airiia- as an ethnic name ( Videvdat 1; Yasht 13.143–44, etc.), where it appears in expressions such as airyāfi daiŋˊhāvō ("Iranian lands"), airyō šayanəm ("land inhabited by Iranians"), and airyanəm vaējō vaŋhuyāfi dāityayāfi ("Iranian stretch of

3182-403: The cult of Ohrmazd. The academic usage of the term Iranian is distinct from the state of Iran and its various citizens (who are all Iranian by nationality), in the same way that the term Germanic peoples is distinct from Germans . Some inhabitants of Iran are not necessarily ethnic Iranians by virtue of not being speakers of Iranian languages. Some scholars such as John Perry prefer

3256-419: The expansion of the Slavic peoples , the Germanic peoples , the Turkic peoples , and the Mongolic peoples ; many were subjected to Slavicization and Turkification . Modern Iranian peoples include the Baloch , the Gilaks , the Kurds , the Lurs , the Mazanderanis , the Ossetians , the Pamiris , the Pashtuns , the Persians, the Tats , the Tajiks , the Talysh , the Wakhis , the Yaghnobis , and

3330-447: The expedition turned back to attempt to rejoin Pizarro, the party being over 100 leagues downstream at this point. He accepted to change the purpose of the expedition to discover new lands in the name of the king of Spain, and the men built a larger boat in which to navigate downstream. After a journey of 600 km (370 mi) down the Napo River, they reached a further major confluence, at a point near modern Iquitos , and then followed

3404-401: The family Lauraceae ) are fairly common in that part of the Amazon and Pizarro probably saw some of these. The expedition reached the mouth of the Amazon on 24 August 1542, demonstrating the practical navigability of the Great River. In 1560, another Spanish conquistador , Lope de Aguirre , may have made the second descent of the Amazon. Historians are uncertain whether the river he descended

3478-658: The forest's ecology by selective cultivation and the use of fire. Scientists argue that by burning areas of the forest repeatedly, the indigenous people caused the soil to become richer in nutrients. This created dark soil areas known as terra preta de índio ("Indian dark earth"). Because of the terra preta, indigenous communities were able to make land fertile and thus sustainable for the large-scale agriculture needed to support their large populations and complex social structures. Further research has hypothesized that this practice began around 11,000 years ago. Some say that its effects on forest ecology and regional climate explain

3552-411: The good Dāityā"). In the late part of the Avesta (Videvdat 1), one of the mentioned homelands was referred to as Airyan'əm Vaējah which approximately means "expanse of the Iranians". The homeland varied in its geographic range, the area around Herat ( Pliny 's view) and even the entire expanse of the Iranian Plateau ( Strabo 's designation). The Old Persian and Avestan evidence is confirmed by

3626-425: The interaction of two antecedent cultures. Its immediate predecessor in the Ural-Tobol steppe was the Poltavka culture , an offshoot of the cattle-herding Yamnaya horizon that moved east into the region between 2800 and 2600 BC. Several Sintashta towns were built over older Poltavka settlements or close to Poltavka cemeteries, and Poltavka motifs are common on Sintashta pottery. Sintashta material culture also shows

3700-490: The internationally driven demand for natural rubber , the Peruvian city of Iquitos became a thriving, cosmopolitan center of commerce. Foreign companies settled in Iquitos, from where they controlled the extraction of rubber. In 1851 Iquitos had a population of 200, and by 1900 its population reached 20,000. In the 1860s, approximately 3,000 tons of rubber were being exported annually, and by 1911 annual exports had grown to 44,000 tons, representing 9.3% of Peru's exports. During

3774-470: The literature of Avesta . The earliest epigraphically attested reference to the word arya- occurs in the Bistun Inscription of the 6th century BC. The inscription of Bistun (or Behistun ; Old Persian : Bagastana ) describes itself to have been composed in Arya [language or script]. As is also the case for all other Old Iranian language usage, the arya of the inscription does not signify anything but Iranian . In royal Old Persian inscriptions,

3848-412: The longer length of the Mantaro. Then distances from Lago Junín to several potential source points in the uppermost Mantaro river were measured, which enabled them to determine that the Cordillera Rumi Cruz was the most distant source of water in the Mantaro basin (and therefore in the entire Amazon basin). The most accurate measurement method was direct GPS measurement obtained by kayak descent of each of

3922-440: The main tributary rivers that drain into the Amazon. Since only 4% of the Amazon's hydropower potential has been developed in countries like Brazil, more damming projects are underway and hundreds more are planned. After witnessing the negative effects of environmental degradation, sedimentation, navigation and flood control caused by the Three Gorges Dam in the Yangtze River, scientists are worried that constructing more dams in

3996-399: The mid-1st millennium BC, the territory of the Iranian peoples stretched across the entire Eurasian Steppe ; from the Danubian Plains in the west to the Ordos Plateau in the east and the Iranian Plateau in the south. The ancient Iranian peoples who emerged after the 1st millennium BC include the Alans , the Bactrians , the Dahae , the Khwarazmians , the Massagetae , the Medes ,

4070-405: The mouth of the Rio Negro, had a population between 1,000 and 1,500. All the remaining villages, as far up as Tabatinga , on the Brazilian frontier of Peru, were relatively small. On 6 September 1850, Emperor Pedro II of Brazil sanctioned a law authorizing steam navigation on the Amazon and gave the Viscount of Mauá ( Irineu Evangelista de Sousa ) the task of putting it into effect. He organised

4144-401: The name ). Gonzalo Pizarro set off in 1541 to explore east of Quito into the South American interior in search of El Dorado , the "city of gold" and La Canela , the "valley of cinnamon ". He was accompanied by his second-in-command Francisco de Orellana . After 170 km (106 mi), the Coca River joined the Napo River (at a point now known as Puerto Francisco de Orellana );

4218-449: The origins of the upstream river basins, situated in the Andes , to the mouth of the river. In this journey, Orellana baptized some of the affluents of the Amazonas like Rio Negro , Napo and Jurua . The name Amazonas is thought to be taken from the native warriors that attacked this expedition, mostly women, that reminded De Orellana of the mythical female Amazon warriors from the ancient Hellenic culture in Greece (see also Origin of

4292-453: The otherwise inexplicable band of lower rainfall through the Amazon basin . Many indigenous tribes engaged in constant warfare . According to James S. Olson , "The Munduruku expansion (in the 18th century) dislocated and displaced the Kawahíb , breaking the tribe down into much smaller groups ... [Munduruku] first came to the attention of Europeans in 1770 when they began a series of widespread attacks on Brazilian settlements along

4366-427: The party stopped for a few weeks to build a boat just upriver from this confluence. They continued downriver through an uninhabited area, where they could not find food. Orellana offered and was ordered to follow the Napo River, then known as Río de la Canela ("Cinnamon River"), and return with food for the party. Based on intelligence received from a captive native chief named Delicola, they expected to find food within

4440-480: The rainy season. Small towns and villages are scattered across the forest, and because its vegetation is so dense, some remote areas are still unexplored. Many settlements grew along the road from Brasília to Belém with the highway and National Integration Program, however, the program failed as the settlers were unequipped to live in the delicate rainforest ecosystem. This, although the government believed it could sustain millions, instead could sustain very few. With

The Amazon River has an average discharge of about 215,000–230,000 m /s (7,600,000–8,100,000 cu ft/s)—approximately 6,591–7,570 km (1,581–1,816 cu mi) per year, greater than the next seven largest independent rivers combined. Two of the top ten rivers by discharge are tributaries of the Amazon river. The Amazon represents 20% of the global riverine discharge into oceans. The Amazon basin

Obtaining these measurements was difficult given the class IV–V nature of each of these rivers, especially in their lower "Abyss" sections. Ultimately, they determined that the most distant point in the Mantaro drainage is nearly 80 km farther upstream compared to Mt. Mismi in the Apurímac drainage, and thus the maximal length of

By the turn of the 20th century, the exports of the Amazon basin were India-rubber , cacao beans , Brazil nuts and a few other products of minor importance, such as pelts and exotic forest produce ( resins , barks, woven hammocks , prized bird feathers , live animals) and extracted goods, such as lumber and gold. Since colonial times,

There is ample evidence that the areas surrounding the Amazon River were home to complex and large-scale indigenous societies, mainly chiefdoms who developed towns and cities. Archaeologists estimate that by the time the Spanish conquistador De Orellana traveled across

4884-516: The social and religious development of higher-altitude civilizations like the Muisca and Incas . Early human settlements were typically based on low-lying hills or mounds. Shell mounds were the earliest evidence of habitation; they represent piles of human refuse (waste) and are mainly dated between 7500 BC and 4000 BC. They are associated with ceramic age cultures ; no preceramic shell mounds have been documented so far by archaeologists . Artificial earth platforms for entire villages are

He uses the same analogue as in differentiating German from Germanic or differentiating Turkish and Turkic . German scholar Martin Kümmel also argues for the same distinction of Iranian from Iranic . The Proto-Indo-Iranians are commonly identified with

5032-411: The term arya- appears in three different contexts: In the Dna and Dse, Darius and Xerxes describe themselves as "an Achaemenid, a Persian, son of a Persian, and an Aryan, of Aryan stock".
