The Tiriyó (also known as Trio) are an Amerindian ethnic group native to parts of northern Brazil, Suriname, and Guyana.

[4] As such, the Tiriyó established contact relatively early with runaway slave groups that settled in the area around the end of the 18th century.

[4] The expeditions in the interior of Suriname in the early 20th century did observe Tiriyós, however they tended to flee when approached, and no useful information could be gathered.

[5] In 1907, De Goeje managed to make contact in the Tumuk Humak expedition resulting in the first dictionary of the Tiriyó language.

[4] These missions tried to concentrate the Tiriyó population in larger villages to more easily convert them to Christianity, and over time, other Indigenous groups such as the Akuriyó joined them here.

[10] The same thing happened with Kwamalasamutu,[6] and in 1997 granman Asongo decided,[11] that part of the population should spread out, also as a defence against encroachment by gold miners and tourist lodges.

[23] Even though the Inter-American Commission on Human Rights ruled in 2007 that all indigenous and tribal peoples have the right to manage, distribute, and effectively control their territory,[24] Article 41 of the Constitution of Suriname states: "Natural resources and resources are the property of the nation and should be mobilized for economic, social and cultural development.

The nation has the inalienable right to take full ownership of its natural resources in order to apply them for the economic, social and cultural development of Suriname.
