In a treaty with the Dutch colonial authorities, the Ndyuka people of Suriname – descended from escaped slaves – gain territorial autonomy.

The Ndyuka people or Aukan people (Okanisi), are one of six Maroon peoples in the Republic of Suriname and one of the Maroon peoples in French Guiana. The Aukan or Ndyuka speak the Ndyuka language. They are subdivided into the Opu, who live upstream of the Tapanahony River in the Tapanahony resort of southeastern Suriname, and the Bilo, who live downstream of that river in Marowijne District.

Maroons are descendants of Africans in the Americas and islands of the Indian Ocean who escaped from slavery, through flight or manumission, and formed their own settlements. They often mixed with Indigenous peoples, eventually evolving into separate creole cultures such as the Garifuna and the Mascogos.
