Relations between the Dutch and the Indigenous peoples of North and South America can be divided into two periods. From 1621 to 1674, Dutch-Indigenous relations were shaped by the attempt of the West India Company to build a transatlantic empire. In Brazil, the Dutch established military alliances with multiple Indian groups. In Guiana (or Guyana), Suriname, the Caribbean, and New Netherland in North America, relations were also shaped by war and trade. From 1675 until 1815, the Dutch presence in the Americas was limited to Guiana (Essequibo, Berbice), Suriname, and a few small Caribbean islands. During this period, Dutch-Indigenous relations were largely shaped by the plantation-slavery system. Indigenous peoples were frequently employed by the Dutch as slave catchers. Christian missions played a limited role in the Dutch Atlantic, with the exception of the Calvinist mission in Dutch Brazil and the Moravian missions in 18th-century Suriname.
