Somoza family in the context of Anastasio Somoza García

The Sandinista National Liberation Front (Spanish: Frente Sandinista de Liberación Nacional, FSLN) is a socialist political party in Nicaragua. Its members are called Sandinistas (Spanish pronunciation: [sandiˈnistas]) in both English and Spanish. The party is named after Augusto César Sandino, who led the Nicaraguan resistance against the United States occupation of Nicaragua in the 1930s.

The FSLN overthrew Anastasio Somoza Debayle in the 1979 Nicaraguan Revolution, ending the Somoza family, and established a revolutionary government in its place. Having seized power, the Sandinistas ruled Nicaragua from 1979 to 1990, first as part of a Junta of National Reconstruction. Following the resignation of centrist members from this Junta, the FSLN took exclusive power in March 1981. They instituted literacy programs, nationalization, land reform, and devoted significant resources to healthcare, but came under international criticism for human rights abuses, including mass execution and oppression of indigenous peoples. They were also criticized for mismanaging the economy and overseeing runaway inflation.

The Nicaraguan Revolution (Spanish: Revolución nicaragüense), or Sandinista Revolution (Spanish: Revolución popular sandinista) was an armed conflict that took place in the Central American country of Nicaragua from 1978 to 1990.

It began with rising opposition to the Somoza dictatorship in the 1960s and 1970s, the overthrow of the dictatorship in 1978–1979, and fighting between the government and the Contras from 1981 to 1990. The revolution revealed the country as one of the major proxy war battlegrounds of the Cold War.

Augusto César Sandino (Latin American Spanish: [awˈɣusto se sanˈdino]; 18 May 1895 – 21 February 1934), full name Augusto Nicolás Calderón Sandino, was a Nicaraguan revolutionary, founder of the militant group EDSN, and leader of a rebellion between 1927 and 1933 against the United States occupation of Nicaragua. Despite being referred to as a "bandit" by the United States government, his exploits made him a hero throughout much of Latin America, where he became a symbol of resistance to American imperialism. Sandino drew units of the United States Marine Corps into an undeclared guerrilla war. The United States troops withdrew from the country in 1933 after overseeing the election and inauguration of President Juan Bautista Sacasa, who had returned from exile.

Sandino was executed in 1934 by National Guard forces of General Anastasio Somoza García, who went on to seize power in a coup d'état two years later. After being elected president by an overwhelming margin in 1936, Somoza García resumed control of the National Guard and established a dictatorship, with the Somoza family dynasty ruling Nicaragua for more than 40 years. Sandino's political legacy was claimed by the Sandinista National Liberation Front (FSLN), which overthrew the Somoza government in 1979 and then ensconced itself in power for more than 40 years.
