The Nicaraguan Revolution (Spanish: Revolución Nicaragüense or Revolución Popular Sandinista, also RPS) encompassed the rising opposition to the Somoza dictatorship in the 1960s and 1970s, the campaign led by the Sandinista National Liberation Front (Frente Sandinista de Liberación Nacional, FSLN) which led to the violent ousting of that dictatorship in 1979, and the subsequent efforts of the FSLN, which governed from 1979 until 1990, to reform the society and economy of the country along socialist lines.
