History of Nicaragua (1979–1990)

In 1979, the Sandinista National Liberation Front (FSLN) overthrew Anastasio Somoza Debayle, ending the Somoza dynasty, and established a revolutionary government in Nicaragua. Following their seizure of power, the Sandinistas ruled the country 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.

Oppositional rebels, known as Contras, formed in 1981 to resist the Sandinista's Junta and received support from the American Central Intelligence Agency. The 1984 elections, described by international observers as fair and free, were boycotted by the main opposition party. The FSLN won the majority of the votes. Those who did oppose the Sandinistas won approximately a third of the seats. Despite the clear electoral victory for the Sandinistas, the Contras continued their violent attacks on both state and civilian targets, until 1989. The FSLN lost elections in 1990 to Violeta Barrios de Chamorro, after revising the constitution in 1987 and after years of resisting the United States-supported Contras, but retained a minority of seats in the legislature.

The FSLN evolved from one of many opposition groups to a leadership role in the overthrow of the Somoza regime. By mid-April 1979, five guerrilla fronts opened under the joint command of the FSLN, including an internal front in the capital city Managua. Young guerrilla cadres and the National Guardsmen were clashing almost daily in cities throughout the country. The strategic goal of the Final Offensive was the division of the enemy's forces. Urban insurrection was the crucial element because the FSLN could never hope to achieve simple superiority in men and firepower over the National Guard.

On June 4, a general strike was called by the FSLN to last until Somoza fell and an uprising was launched in Managua. On June 16, the formation of a provisional Nicaraguan government in exile, consisting of a five-member Junta of National Reconstruction, was announced and organized in Costa Rica. The members of the new junta were Daniel Ortega (FSLN), Moisés Hassan (FPN), Sergio Ramírez (the "Twelve"), Alfonso Robelo (MDN) and Violeta Barrios de Chamorro, the widow of La Prensa's director Pedro Joaquín Chamorro. By the end of that month, with the exception of the capital, most of Nicaragua was under FSLN control, including León and Matagalpa, the two largest cities in Nicaragua after Managua.
