Revolutionary Movement 13th November

Revolutionary Movement 13th November (in Spanish: Movimiento Revolucionario 13 Noviembre) was a leftist movement in Guatemala. MR-13 was founded in 1960 by a group of dissident officers. It grew partly out of the popular protests against the government of President Miguel Ydígoras Fuentes following his election in 1958. It was led by Luis Augusto Turcios Lima, Marco Antonio Yon Sosa and Luis Trejo Esquivel. Alejandro de León, co-founder of the group, was captured and shot by the judicial police in 1961. In 1963, MR-13 joined the Rebel Armed Forces (FAR).

MR-13 nominally continued to exist until 1973, after it was severely hampered in the 1966-67 counterinsurgency by the Guatemalan government.
