Throughout the 19th and 20th centuries the indigenous peoples of the Caribbean coast came to rely upon private investment and enterprises for socio-economic stability. In adherence to socialist policies, the Sandinista-dominated Nicaraguan government in the 1980s sought to nationalize all private institutions, which resulted in a reduction of private investment on the Caribbean coast. Many indigenous groups resented the government for its interference in the indigenous economy and regional autonomy. The Rama people were one of many indigenous groups to join the Contras, a group of anticommunist guerrillas, some of whom were backed by the CIA, dedicated to fighting the Sandinista regime. As a result of the Nicaraguan Revolution, many Rama were displaced from their homes and traditional lands.
