The Yanomami, also spelled Yąnomamö or Yanomama, are a group of approximately 35,000 indigenous people who live in some 200–250 villages in the Amazon rainforest on the border between Venezuela and Brazil.
The ethnonym Yanomami was produced by anthropologists on the basis of the word yanõmami, which, in the expression yanõmami thëpë, signifies "human beings." This expression is opposed to the categories yaro (game animals) and yai (invisible or nameless beings), but also napë (enemy, stranger, non-Indian).
According to ethnologist Jacques Lizot:
Yanomami is the Indians' self-denomination ... the term refers to communities disseminated to the south of the Orinoco, [whereas] the variant Yanomawi is used to refer to communities north of the Orinoco. The term Sanumá corresponds to a dialect reserved for a cultural subgroup, much influenced by the neighboring Ye'kuana people. Other denominations applied to the Yanomami include Waika or Waica, Guiaca, Shiriana, Shirishana, Guaharibo or Guajaribo, Yanoama, Ninam, and Xamatari or Shamatari.
The first report of the Yanomami to the Northern world is from 1654, when a Spanish expedition under Apolinar Diez de la Fuente visited some Ye'kuana people living on the Padamo River. Diez wrote:
By interlocution of an Uramanavi Indian, I asked Chief Yoni if he had navigated by the Orinoco to its headwaters; he replied yes, and that he had gone to make war against the Guaharibo [Yanomami] Indians, who were not very brave ... and who will not be friends with any kind of Indian.
From approximately 1630 to 1720, the other river-based indigenous societies who lived in the same region were wiped out or reduced as a result of slave-hunting expeditions by the conquistadors and bandeirantes. How this affected the Yanomami is unknown. Sustained contact with the outside world began in the 1950s with the arrival of members of the New Tribes Mission as well as Catholic missionaries from the Society of Jesus and Salesians of Don Bosco.
