On July 17, 1979 the Nicaraguan dictator Anastasio Somoza Debayle resigned and fled to Miami as the Sandinista National Liberation Front closed on Managua, ending more than four decades of rule by the Somoza family dynasty and bringing the Sandinistas to power two days later. The Somoza family had dominated Nicaragua since the 1930s, and Anastasio Somoza Debayle's rule had grown intolerable amid corruption, repression, and the 1978 assassination of opposition journalist Pedro Joaquin Chamorro, which galvanized a broad insurrection led by the Sandinistas (FSLN). After months of escalating civil war and heavy fighting, and with US support withdrawn, Somoza resigned on July 17, 1979 and flew into exile.
A brief interim government could not hold, and on July 19, 1979 the Sandinistas entered Managua and took power. Somoza settled in Paraguay, where he was assassinated in 1980.

Sources
Nicaraguan dictator General Anastasio Somoza Debayle resigned and fled to Miami, Florida on July 17, 1979, and the Sandinista National Liberation Front concluded a successful revolutionary campaign against the US-backed Somoza dictatorship and assumed power in Nicaragua.
The Somoza family dynasty had ruled Nicaragua since the 1930s, and the 1978 assassination of opposition journalist Pedro Joaquin Chamorro helped galvanize a broad insurrection led by the FSLN that culminated in Somoza's fall in July 1979.
SOURCE REVIEWEDBritannica, Nicaragua: The Sandinista revolutionopen source ↗
The Sandinista National Liberation Front assumed power in Nicaragua after Somoza Debayle resigned and fled, ending the US-backed dictatorship, with the Sandinistas entering Managua in July 1979.
Coding note: the dataset labels this a rebel coup, reflecting that Somoza was overthrown by the Sandinista insurgency (FSLN) after a prolonged civil war; he resigned, fled to Miami, and was not captured, matching the dataset's fled-the-country fate. Neutrality: the Nicaraguan Revolution is a contested Cold War subject; the record confines itself to the documented sequence (Somoza's resignation and flight on July 17, the Sandinista entry into Managua on July 19) and attributes characterizations to their sources. Context: the 1978 assassination of journalist Pedro Joaquin Chamorro and the withdrawal of US support under the Carter administration are recorded as documented factors. Tragic later turn flagged: Somoza was assassinated in Asuncion, Paraguay in September 1980, a separate later event; the subsequent Contra war against the Sandinista government is later context, not part of this record. This ended the Somoza family's decades-long dynasty.
Cross-Reference
Only one dataset carries it. One of the three reference datasets we check against carries this event; the others do not list it. That is not a contradiction — the datasets cover different periods and use different thresholds — but it means the record has had less outside corroboration.
