100-568: A fishing and hunter-gatherer lifestyle. Because of Christopher Columbus' misunderstanding of the continent at which he had arrived, the native population were and are denominated "índios" by the Portuguese. Approximately two thousand Indian tribes lived in the region in the sixteenth century, perhaps amounting to some millions of people, but phenomena such as disease and assimilation to Brazilian culture caused their numbers to fall to approximately three hundred thousand, and two hundred tribes, by

150-574: A possession marker at the upper Japurá River in 1639. Soon after that the Portuguese bandeirante António Raposo Tavares , whose bandeira , leaving the captaincy of São Vicente travelling overland, reached the Andes, and following the Amazon River, returned to Belém, visiting a total of about 12,000 kilometres (7,500 mi), between 1648 and 1651. Tropical jungle is hostile and impenetrable as well as European settlements were exclusively along

200-511: Is tropical jungle ; cities are clustered along navigable waterways and are accessible only by boat or plane. The capital and largest city is Manaus , a modern city of 2.1 million inhabitants in the middle of the jungle on the Amazon River, 1,500 km upstream from the Atlantic Ocean . Nearly half the state's population lives in the city; the other large cities, Parintins , Manacapuru , Itacoatiara , Tefé , and Coari are also along

250-429: Is a narrow piece of land connecting two larger areas across an expanse of water by which they are otherwise separated. A tombolo is an isthmus that consists of a spit or bar , and a strait is the sea counterpart of an isthmus, a narrow stretch of sea between two landmasses that connects two larger bodies of water. Isthmus and land bridge are related terms, with isthmus having a broader meaning. A land bridge

300-595: Is a populated place today, San Pablo, now the municipality of São Paulo de Olivença . Starting about 1580, without effective occupation, English, Dutch, French (and even some Irish) searching for so-called Drogas do Sertão (spices of the backlands ) had established some outposts upstream of the mouth of the Amazon. From at least the time of the Tordesillas Treaty in 1494 until the Treaty of Madrid in 1750,

350-399: Is an isthmus connecting Earth's major land masses. The term land bridge is usually used in biogeology to describe land connections that used to exist between continents at various times and were important for the migration of people and various species of animals and plants, e.g. Beringia and Doggerland . An isthmus is a land connection between two bigger landmasses, while a peninsula

400-708: Is named after the Amazon River , and was formerly part of the Spanish Empire 's Viceroyalty of Peru , a region called Spanish Guyana . It was settled by the Portuguese moving northwest from Brazil in the early 18th century and incorporated into the Portuguese empire after the Treaty of Madrid in 1750. It became a state under the First Brazilian Republic in 1889. Most of the state

450-410: Is one of the oldest in the Amazon, originating in a Mercedarian Indian mission founded in 1663. By the early 18th century, they were destroyed by the Portuguese, depopulated by smallpox, or their indigenous residents taken away as slaves by Portuguese Bandeirantes. A few were taken over by Portuguese Carmelites. The destruction of the missions was the end of Spanish claims in western Amazonia. Only one

500-609: Is rather a land protrusion that is connected to a bigger landmass on one side only and surrounded by water on all other sides. Technically, an isthmus can have canals running from coast to coast (e.g. the Panama Canal ), and thus resemble two peninsulas; however, canals are artificial features distinguished from straits . The world's major isthmuses include: Of historic importance were: The cities of Auckland , Madison , Manila , and Seattle are located on isthmuses. Canals are often built across isthmuses, where they may be

550-636: The Andes Mountains and explored the course of the river to the Atlantic Ocean. The indigenous people called this river the Conoris . The myth of women warriors on the river has spread in the accounts and books, without any popular scope, still making those regions to receive names of warriors of Greek mythology, the Amazons — among them the largest river in the region that became known as

600-578: The Javari and the Carmelite aldeia of São Pedro; the other at the western mouth of the great river Japurá. This was the beginning of what came to be called the Jesuit–Carmelite War . Antidote to settlement was disease: fierce smallpox epidemics in 1661, 1695, 1724, and 1743/49 left the region nearly depopulated. A Carmelite Friar had notable success with the method of variolation in 1729, but

650-646: The Portuguese Empire by the First Treaty of San Ildefonso . The State also includes territory from failed attempts at colonization by the European powers, such as England and the Dutch empire. The first Spanish expedition was by Francisco de Orellana in conjunction with Catholic priest Gaspar de Carvajal , who documented the expedition. He reported a conflict against indigenous women which led to

700-464: The Province of Amazonas was officially created by Emperor Pedro II in 1850. From the mid-19th century, the territory began to receive migrants from the northeast seeking a better life. Attracted by the rubber boom, they settled in important Amazonian cities such as Manaus, Tabatinga, Parintins, Itacoatiara and Barcelos, the first capital of Amazonas. The state had an era of splendor in the 1890s, at

750-620: The Amazon River flowed westward, perhaps as part of a proto-Congo (Zaïre) river system from the interior of present-day Africa when the continents were joined as part of western Gondwana . Fifteen million years ago, the Andes were formed by the collision of the South American Plate with the Nazca Plate (eastern Pacific oceanic) plate. The rise of the Andes and the linkage of the Brazilian and Guyana bedrock shields, blocked

800-851: The Amazon River in the eastern half of the state. The name was originally given to the Amazon River that runs through the state by the Spaniard Francisco de Orellana in 1541. Claiming to have come across a warlike tribe of Natives, with whom he fought, he likened them to the Amazons of Greek mythology , giving them the same name of Río de las Amazonas . 1616 Captaincy of Maranhão begins westward expansion 1751 Maranhão reconstituted as state of Grão-Pará e Maranhão 1755 Captaincy of Rio Negro split off 1757 Captaincy of Rio Negro rejoined 1772 Grão-Pará e Rio Negro split from Grão-Pará e Maranhão. 1775 Captaincy of Grão-Pará of state of Brazil. 1821 Province of Pará 1822 Pará province of independent Brazil. 1832 Creation of Judicial District of

850-716: The Amazon River. Early publications, as was the style of the day, called the river after its European explorer, the Orellana . Also in the 16th century, there were the expeditions of conquistadores Pedro de Ursúa and Lope de Aguirre in search of the legendary El Dorado , the Lost City of Gold (1559–1561) Spanish Jesuit missions were the first settlements upstream on the Amazon. As many as 30 missions were founded in Amazon territory, seven in Brazil, between 1638 and 1727. The municipality of Silves on an island of Lake Saracá

900-540: The Amazonas State, being the center of important artistic and cultural events. Bloomed so trade in luxury products and superfluous, with men and women from all over the world parading its streets and avenues, at purchase of the so-called "black gold" , as was dubbed the natural rubber, to resell big profits in the main capitals of Europe and in the United States from 1910, difficult times began, due to

Despite the adoption in 1957, that project has only been in fact deployed, by Decree-Law number 288 of 28 February 1967. Isthmus An isthmus ( / ˈ ɪ s m ə s , ˈ ɪ s θ m ə s / ; pl. : isthmuses or isthmi )

1000-1013: The Jesuits, Carmelites, Capuchines and Franciscans: the Jesuits restricted their activities to the south bank of the Amazon upstream to the mouth of the Madeira; the north shore of the Amazon as far as the Trombetas fell to the Franciscans, to the mouth of the Rio Negro to the Mercedarians, and the Negro itself and the Solimoes to the Carmelites. The Portuguese Carmelites got a later start than the Spanish Jesuits, but their impact

1100-619: The Spanish and Portuguese possessions, the Viceroyalty of Peru (and successor states) and Grão-Pará region of Brazil, was set between 1781 and 1791 by negotiation. In 1821, Grão-Pará and Rio Negro provinces became the unified Grão-Pará . The following year, Brazil proclaimed its independence and Grão-Pará became the Province of Pará of state of Brazil. When Emperor Pedro I declared independence from Portugal, in 1822, he had to fight also

1200-430: The area of the confluence of the Rio Negro and Amazon Rivers, in upper Amazonia. While the Treaty of Madrid in 1750 implicitly recognized the principle of uti possiditis , it did not actually specify the northern borders of the country. At that time, the border of contention between Spanish and Portuguese domains was in the upper Solimões, at the junction of the Rio Negro. In the upper Salomoes, Spanish missionary influence

1250-650: The autonomy of the Amazonas region as a separate province of Pará. The rebellion was suppressed, but the Amazons were able to send a representative to the Imperial Court, Friar José dos Santos Inocentes , who got up the creation of the District of the Upper Amazon. During Cabanagem in 1835–40, the Amazon remained loyal to the imperial government and not joined the revolt. As a sort of reward for loyalty,

1300-633: The current name of the river, and then to the current name of the region and the state (Amazonas in English: Amazons ). The second Spanish expedition was by Pedro de Ursúa , intending to prove the previous expedition, but resulted in the Spanish Kingdom dropping the attempt to colonize the region. After the unification of the Iberian kingdoms, Portugal launched an expedition on the river [but in reverse from Francisco de Orellana, at

1350-539: The emergence of Colombia , Ecuador , Venezuela and Panama . Brazil signed the Treaty Vásquez Cobo–Martins (1908) (with those countries) finally entitling those possessions in the north to Brazil. One region is marked by the geodesic line Apóporis-Tabatinga; and the other is the municipal area of São Gabriel da Cachoeira , on the Brazil-Colombia border . By the Treaty of Tordesillas (1494),

1400-464: The end of the twentieth century. Certain uncontacted tribes still exist in the region. In the colonial time, the territory which today belongs to the State of Amazonas, was a combination of treaties, expeditions, evangelism and military occupations. Scarce but recorded claims and indigenous uprisings in the region, were initially made by the Spanish Empire through the Treaty of Tordesillas and after

1450-566: The frontier of the northernmost captaincy of Maranhão with the expulsion of the French from São Luis in 1615, and the founding of Belém at the mouth of the Amazon in 1616. Exploration and colonization thence followed the waterway upstream. There are accounts of Portuguese Carmelite missionaries active in the Solimões area, upstream of the Rio Negro, as early as the 1620s, but permanent settlements weren't established for another 80 years, so

1500-463: The ice ages ended, the forest was again joined, and the species that were once one, had diverged significantly enough to be designated as separate species, adding to the tremendous diversity of the region. About 6,000 years ago, sea levels rose about 130 meters, once again causing the river to be inundated like a long, giant freshwater lake. The pre-Columbian Amazonas was inhabited by seminomadic peoples whose livelihood mixed occasional agriculture with

1550-507: The island of Aibi near the mouth of Lake Arauató , followed by São Gabriel , founded in 1668 as by Franciscan Friar Teodózio [or Teodósio] da Veiga and Captain Pedro da Costa Favela on the Rio Negro, near the mouth of the Rio Aruím . In 1761, a fort was built on the location, and the settlement became the town of São Gabriel da Cachoeira . The first missionary aldea of the Portuguese in

1600-658: The mouth of the river to the site of the present-day city of Quito , capital of Ecuador ], with the intention of attaching Spanish lands (comprising the current territory of the Brazilian Amazon ) to the Portuguese Kingdom . After the dissolution of the Iberian Union , Portuguese and Spanish possessions in the region were undefined, resulting in internal conflicts in the region between Portugal and Spain . The Portuguese Crown later asserted

1650-450: The peak of the rubber boom. However, the economic gains were largely the result of great human suffering: untold thousands of enslaved Amerindian seringueiros (rubber tappers) died through disease and overwork. Manaus, which already boasted as the capital administrative of the State, experienced a great population growth and the economic advancement, resulting mainly from exports of raw materials until then exclusively from Amazon Region. With

1700-437: The principle of uti possidetis , with respect to the region. This was the first assertion of the principle from Roman law of uti possidetis, ita possideatis , (Latin, "who has possession, has dominion"), analogous to English common law "Squatters rights" . Due account may have been taken of John Locke's labour theory of property. Conflicting issues arose between what was granted by law in the Treaty of Tordesillas (1494), and

1750-580: The provinces of Grão-Pará and Maranhão. In 1823, a ship commanded by British officer John Pascoe Grenfell arrived at the port of Belém , to combat rebels. Only in August 1824 did the new governor swear loyalty to the Brazilian Emperor. The Province of Pará , including the comarca of Rio Negro, the upper Amazon region, was incorporated into the Empire of Brazil in 1824. A revolt in 1832 demanded

1800-477: The records are nebulous. The first documented Portuguese foray into upper Amazonia was the expedition of Portuguese explorer and military officer Pedro Teixeira , who followed the great river from the Atlantic Ocean to Quito, Ecuador with 70 soldiers and 1,200 Indians in forty-seven great canoes (1637–1639). He returned by the same route, arriving back in Belem in 1639. According to the Portuguese, Pedro Teixeira placed

1850-672: The region of the upper Amazon was part of the Spanish Viceroyalty of Peru ( Viceroyalty of New Granada after 1717). Everything north of the Amazon (Solimões) and west of the Nhamundá River (Yamundá, in Spanish), an affluent of the left bank of the Amazon that forms the boundary of Amazonas with Pará, was known as Spanish Guyana. Portuguese expansion westward and northward of the Torsedillas Line began from

1900-474: The river and caused the Amazon to become a vast inland sea. Gradually this inland sea became a massive swampy, freshwater lake and the marine inhabitants adapted to life in freshwater. For example, over 20 species of stingray, most closely related to those found in the Pacific Ocean, can be found today in the fresh waters of the Amazon. About ten million years ago, waters worked through the sandstone to

1950-659: The strong competition of natural rubber planted in rubber plantations the Asian continent, to European and American markets with superior advantages, which ultimately enact bankruptcy of Amazonian economy. By the late 19th century, the Brazilian rubber monopoly was slowly dying, as British and Dutch plantations in South-East Asia were producing cheaper, superior quality rubber, and by 1900 the Amazonas state had fallen into serious economic decline. Free trade zone of Manaus (also called Manaus Industrial Pole or Industrial Pole of

2000-521: The subsequent reality of colonial expansion: the Spanish, eastward from the Pacific coastal plains (though restrained by the Andes ), and the Portuguese, westward (aided by the waterways and lowlands of the mighty Amazon). The Treaty of Madrid (13 January 1750) – that determined the border between the Spanish possessions and southern Portuguese Brazil – had first enunciated the principle that new states, at

2050-478: The technique was not propagated. The Jenner cowpox vaccine was not introduced in Brazil until 1808. Variolation was prohibited in 1840, and vaccination was mandated in 1854. But epidemics got worse until finally petering out around the turn of the century. Within the project of occupying the Amazon hinterland, was formed the royal captaincy of São José do Rio Negro subordinate to Para, in Mar. 1755, with headquarters in

2100-401: The time of their creation shall have dominion over the lands that were settled as colonies. It implicitly opened the door to claims by prior possession in the vast lands of the north. After the independence of Brazil in 1822, the current borders of the Amazonas State were still undefined – at that time being with Gran Colombia . The internal conflicts within that neighbour country resulted in

2150-482: The village of Mariuá, (now Barcelos). The boundary between the Portuguese and Spanish domination of the Amazon was eventually fixed at the Rio Javari (river that rises on the border between Amazonas state, Brazil, and Loreto department, Peru) by the Treaty of Madrid in 1750. By the mid-18th century, the effective boundary between the two empires, the Spanish Viceroyalty of Peru and Portuguese Brazil, had shifted to

2200-472: The waterways. Portuguese expansion generally was east to west, and from the main channel, the Solimões, north and south along the tributaries. The character of the settlements was of three kinds: defense and occupation ( fortes ), economic ( feitorias ), and evangelical ( missões ). The first permanent Portuguese settlements in the region were Itacoatiara 176 km east of Manaus, founded in 1655 by Portuguese Jesuit Padre António Vieira as Mission of Aroaquis on

2250-472: The wealth generated by the production and export of natural rubber ( Hevea brasiliensis ), the amazonian capital received large works such as the port of Manaus, the Amazonas Opera House , Palace of Justice, Reservoir of Mocó , the first network of electric energy and public transport services as trams. Vista as a reference, your headquarters became a symbol of prosperity and civilization for

2300-584: The west and the Amazon began to flow eastward. At this time the Amazon rainforest was born. During the Ice Age, sea levels dropped and the great Amazon lake rapidly drained and became a river. Three million years later, the ocean level receded enough to expose the Central American isthmus and allow mass migration of mammal species between the Americas. The Ice Ages caused tropical rainforest around

2350-731: The whole Amazon basin was in the area of the Spanish Crown. The mouth of a great river was explored by Spanish conquistador Vicente Yáñez Pinzón , who reached it in February 1500, with his cousin Diego de Lepe . He called the river Río Santa María de la Mar Dulce (River of Saint Mary of the Sweet Sea) on account of the large freshwater estuary extending into the sea at its mouth. In 1541, Spanish conquistadores Gonzalo Pizarro and Francisco de Orellana , from Quito , Ecuador, crossed

2400-480: The world to retreat. Although debated, it is believed that much of the Amazon reverted to savanna and montane forest . Savanna divided patches of rainforest into "islands" and separated existing species for periods long enough to allow genetic differentiation. A similar rainforest retreat took place in Africa, where Delta core samples suggest that even the mighty Congo watershed was void of rainforest at this time. When

2450-547: Was being displaced, and the Viceroy was indifferent to colonization, but Portuguese settlements were not yet established. Part of the northern boundary between Brazil and what was then British Guyana, was set by the Spanish Boundary-line Commission of Yturriaga and Solano (1757–1763). After two indecisive wars between Portuguese and Spanish colonial forces 1761–1763 and 1776–1777, the border between

2500-550: Was more durable. Between 1697 and 1757, they established eight missions on the Solimões and nine on the Rio Negro. In addition, there were a few Portuguese Jesuit missions in the Solimões. In 1731, Portuguese Jesuits received orders from the Governor Luiz de Vasconcellos Lobo to establish two aldeias above the mouth of the Rio Negro, one on the right bank of the Orellana Solimões , between the eastern mouth of
