Montoneros

Montoneros (Spanish: Movimiento Peronista Montonero-MPM) was an Argentine leftist urban guerrilla group, active during the 1960s and 1970s. The name is an allusion to 19th century Argentinian history.

After Juan Perón's return from 18 years of exile and the 1973 Ezeiza massacre, which marked the definitive split between left and right-wing Peronism, the Montoneros were expelled from the Justicialist party in May 1974 by Perón. The group was almost completely destroyed by 1977, during the Dirty War.
