The Xingu National Park also known as Xingu Indigenous Territory (TIX), which covers 10,200 square miles, was created in 1960 by the famous Brazilian Indigenists Orlando, Claudio and Leonardo Villas Boas. A further 45,000 square miles bordering the Xingu National Park was officially declared indigenous territory in August 1993 after Rainforest Organization spearheaded alongside the tribal leader Raoni Metuktire the first worldwide campaign to draw attention to the dangers of deforestation in the Amazon and the risk of extinction faced by its indigenous populations.

With the support of the Brazilian government and 12 sister organizations, Rainforest Organization raised the necessary funds to demarcarte the boundaries of this new indigenous territory bordering the Xingu National Park, thus creating, with an overall area of over 55,000 square miles, one of the largest continuous rainforest reserves on the planet.
