Coordinadora Revolucionaria de Masas (Revolutionary Mass Coordination), a coordination of revolutionary mass organizations in El Salvador formed on January 11, 1980.
The major action in its history was a January 22, 1980, demonstration, in commemoration of the 1932 Salvadoran peasant uprising. Between 200,000 and 350,000 people took to the streets this day in a country with just 5 million inhabitants. The security forces attacked the march with snipers located in the National Palace and other buildings in downtown San Salvador against the contingents of Frente de Acción Popular Unificado (United Popular Action Front) (FAPU) and Unión Democrática Nacionalista. The contingents of Bloque Popular Revolucionario and Ligas Populares 28 de Febrero (LP-28) had not yet begun to march when the demonstration was dissolved.
Later marches of the CRM were dispersed with particular dispatch by the National Guard, Hacienda Police, National Police and paramilitaries. The last big demonstration of the CRM occurred on March 24, 1980, during the funeral of Archbishop Oscar Romero, assassinated the week before. The repression of the march was brutal and the marchers began to leave the streets and the CRM devolved into a coordinating body of unions, student, farmer and worker groups. The last actions were during the general offensive of 1981 (la fallida).
Every organization in the CRM corresponded to a military-political organization.
Other organizations involved in the CRM were:
After a short period of existence, CRM merged with Frente Democrático Salvadoreño to form Frente Democrático Revolucionario.
