El Salvador: 20th Century Developments

El Salvador's twentieth century was shaped by deep-rooted inequities in land ownership and political power that stretched back to the previous century. Salvadoran elites, backed by the military, resisted meaningful economic reform for decades, and popular demands for change were repeatedly met with force. This pattern culminated in 1932 in La Matanza, a massacre in which the army killed an estimated 30,000 peasants in a pre-emptive crackdown on a planned uprising, a trauma that left a lasting mark on the country's political memory.

Those unresolved tensions erupted into full civil war beginning around 1979-1980, pitting the military-dominated government against the Farabundo Martí National Liberation Front, a coalition of leftist guerrilla groups. Cold War anxieties led the United States to supply substantial military and economic aid to the Salvadoran armed forces, which extended the conflict even as it strengthened the government's position. The twelve-year war was marked by widespread human rights abuses, including the massacre of civilians at El Mozote.

The fighting ended with the signing of the Chapultepec Peace Accords in January 1992, which restructured the armed forces, established a new civilian police force, and allowed the FMLN to convert from an insurgent movement into a legal political party. The accords brought a formal close to one of Central America's deadliest twentieth-century conflicts, though the social and economic disparities that had helped ignite the war continued to shape Salvadoran politics well beyond 1992.
