The Nicaraguan Revolution encompassed the rising opposition to the Somoza dictatorship in the 1960s and 1970s, the campaign led by the Sandinista National Liberation Front (FSLN) to oust the dictatorship in 1978–79, the subsequent efforts of the FSLN to govern Nicaragua from 1979 to 1990, and the Contra War, which was waged between the FSLN-led government of Nicaragua and the United States–backed Contras from 1981 to 1990. The revolution marked a significant period in the history of Nicaragua and revealed the country as one of the major proxy war battlegrounds of the Cold War, attracting much international attention.

The Somoza family is a political family which ruled Nicaragua for forty-three years – from 1936 to 1979. Their family dictatorship, founded by Anastasio Somoza García, was continued by his two sons Luis Somoza Debayle and Anastasio Somoza Debayle. Anastasio Somoza García served as the President of Nicaragua from 1937 until 1956. He was succeeded by his elder son, Luis Somoza Debayle, who held the presidency from 1957 to 1963. The younger Somoza son, Anastasio Somoza Debayle, had two presidential terms: 1967–1972 and 1974–1979. Although the Somozas did not hold the presidency for the full forty-three years, they continued to rule through puppet presidents and via their control of the National Guard.
