The Sandinistas Overthrow the Somoza Dynasty

On July 19, 1979, fighters of the Sandinista National Liberation Front (FSLN) entered Managua, completing the collapse of a dynastic dictatorship that had controlled Nicaragua since 1937. Anastasio Somoza Debayle had resigned two days earlier and departed into exile in Miami, leaving behind a nation exhausted by conflict. The family rule established by his father, Anastasio Somoza Garcia, had maintained its grip through political patronage, extensive property holdings, and the loyal violence of the United States-trained National Guard. After decades of smoldering resistance, popular insurrections in cities across the country finally made the regime untenable.

The FSLN was formally organized in 1961 by student activists including Carlos Fonseca Amador, Silvio Mayorga, and Tomas Borge Martinez. Initially consisting of around twenty members, the group adopted guerrilla methods inspired by Fidel Castro and Che Guevara. Early rural incursions suffered devastating setbacks, and Mayorga was killed near Matagalpa while Fonseca fell in combat in 1976. Despite severe losses and internal ideological divisions, the Sandinistas slowly widened their base among students, peasants, and civic groups, bolstered by arms, intelligence, and logistical support from Cuba.
