Main article: Indigenous peoples in Brazil
Within Brazil's current borders, most native tribes who were living in the land by the year 1500 are thought to have descended from the first wave of migrants from North Asia (Siberia), who are believed to have crossed the so-called Bering Land Bridge at the end of the last Ice Age, around 9000 BC. At the time of European discovery, the territory of modern Brazil had as many as 2,000 nations and tribes, an estimated total population of nearly 3,000,000 Amerindians. A somewhat dated linguistic survey found 188 living indigenous languages with 155,000 total speakers. On 18 January 2007, Fundação Nacional do Índio reported that it had confirmed the presence of 67 different uncontacted tribes in Brazil, up from 40 in 2005. With this addition Brazil has now overtaken the island of New Guinea as the country having the largest number of uncontacted peoples. When the Portuguese arrived in 1500, the Indians were mostly semi-nomadic tribes, living mainly on the coast and along the banks of major rivers.
Unlike Christopher Columbus, who thought he had reached the East Indies, the Portuguese, most notably by Vasco da Gama, had already reached India via the Indian Ocean route when they reached Brazil. Nevertheless the word índios ("Indians"), was by then established to designate the peoples of the New World and stuck being used today in the Portuguese language to designate these peoples, while the people of India, Asia are called indianos in order to distinguish the two peoples. Initially, the Europeans saw the natives as noble savages, and miscegenation of the population began right away. Tribal warfare, cannibalism and the pursuit of brazilwood for its treasured red dye convinced the Portuguese that they should civilise the Indians.
