The Sandinista rebels overthrow the government of the Somoza family in Nicaragua.

Anastasio "Tachito" Somoza Debayle (Spanish: [anastasjo somosa eajle]; 5 December 1925 17 September 1980) was a Nicaraguan dictator and officially the President of Nicaragua from 1 May 1967 to 1 May 1972 and from 1 December 1974 to 17 July 1979. As head of the National Guard, he was de facto ruler of the country between 1972 and 1974, even during the period when he was not the de jure ruler.

Somoza Debayle succeeded his older brother in office. He was the last member of the Somoza family to be president, ending a dynasty that had been in power since 1937. After insurgents led by the Sandinista National Liberation Front (Spanish: Frente Sandinista de Liberacin Nacional; FSLN) were closing in on Managua in July 1979, Somoza fled Nicaragua. Power was ceded to the Junta of National Reconstruction. He was assassinated in 1980 while in exile in Paraguay.

The Sandinista National Liberation Front (Spanish: Frente Sandinista de Liberación Nacional, FSLN) is a socialist political party in Nicaragua. Its members are called Sandinistas [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 1979, ending the Somoza dynasty, 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 a policy of mass literacy, devoted significant resources to health care, and promoted gender equality but came under international criticism for human rights abuses, mass execution and oppression of indigenous peoples. A US-backed group, known as the Contras, was formed in 1981 to overthrow the Sandinista government and was funded and trained by the Central Intelligence Agency. In 1984 elections were held but were boycotted by some opposition parties. The FSLN won the majority of the votes, and those who opposed the Sandinistas won approximately a third of the seats. The civil war between the Contras and the government continued until 1989. After revising the constitution in 1987, and after years of fighting the Contras, the FSLN lost the 1990 election to Violeta Barrios de Chamorro but retained a plurality of seats in the legislature.

The FSLN is now Nicaragua's sole leading party. In the 2006 Nicaraguan general election, former FSLN President Daniel Ortega was reelected President of Nicaragua with 38.7% of the vote to 29% for his leading rival, bringing in the country's second Sandinista government after 17 years of other parties winning elections. Ortega and the FSLN were reelected in the presidential elections of 2011, 2016, and 2021.
