The Farabundo Marti National Liberation Front (FMLN) was a Marxist-Leninist insurgency movement operationally active in El Salvador from 1980 to 1992. The goal of the FMLN was to overthrow the military dictatorship that had ruled El Salvador since 1930 and replace it with a Communist government. The group was named after Farabundo Marti, a Salvadoran Communist revolutionary that led an unsuccessful and brutally-repressed revolt in 1932, during the height of El Salvador's economic and social depression.<br /><p><br />In 1980, the FMLN was formed as an umbrella group representing the common interests of the five main leftist organizations of El Salvador: the Central American Workers' Revolutionary Party (PRTC), the People's Revolutionary Army (ERP), the Farabundo Marti Popular Liberation Forces (FPL), the Armed Forces of National Resistance (FARN), and the Communist Party of the Armed Forces of Liberation (FAL). The FMLN served to pool the limited resources of these groups and coordinate the strategies and tactics of the Communist insurgency in El Salvador.<br /><p><br />The FMLN was organized into a political wing responsible for propaganda and public diplomacy and a military wing responsible for armed operations. Initially, the FMLN developed a three-pronged strategy. First, they sought to secure their rural support base. Second, they conducted raids against government forces and economic infrastructure to de-legitimize the regime. Finally, they waged a propaganda war in urban areas with the aim of inciting a popular uprising against the government.<br /><p><br />Politically-inspired by Communists the world over and financially-supported by the Communist regimes of Castro and the Nicaraguan Sandinistas, the FMLN conducted two relatively-conventional offensives in 1982 that were unsuccessful due to limited resources, an easily-disrupted supply chain exacerbated by communication difficulties, and internal disputes over command authority and strategy. After resolving some of these issues with a new influx of communications equipment and American-made weapons purchased on the black market and supplied by Nicaragua, the FMLN reached the height of its strength in 1983, numbering up to 12,000 members at one point. The FMLN embarked on what was to be its final conventional offensive in September 1983, escalating the scale and intensity of warfare in comparison to previous engagements. Still, the FMLN was not able to win decisively.<br /><p><br />After the US provided military aid to the government of El Salvador, the FMLN was forced to shift strategies and wage fully-asymmetrical warfare. The whole movement trimmed its size, reorganized into smaller units more conducive to guerrilla warfare, and moved into urban areas, especially San Salvador. In the last half of the 1980s, the FMLN employed terrorist tactics such as kidnappings, arson, and bombings to destabilize the regime. Due to the substantial influence that American financial support had on strengthening El Salvador's counterinsurgency prowess, US assets in El Salvador also became targets during this time. Notably, four US Marine security guards were massacred at a roadside caf&#233; in June 1985.<br />
