The Revolutionary Independent Labour Movement (Movimiento Obrero Independiente y Revolucionario), or MOIR, is a left-wing party in Colombia that was founded in September 1969.

[2] At its founding, the MOIR believed that in Colombia it was necessary to first carry out Mao Zedong's New Democracy Revolution to achieve socialism, complemented by the formation of a true Workers' Party and an Agrarian Revolution due to the semi-feudal character of the country, all leading to the formation of a Anti-Imperialist United Front for Sovereignty and Democracy, where all sectors of society could fit against foreign domination.

It split from the Peasant Student Workers Movement (Movimiento Obrero Estudiantil y Campesino, MOEC), headed by Francisco Mosquera, due to internal differences by rejecting armed struggle and adopting a marxist-leninist ideology.

It's youth organization, Juventud Patriótica (JUPA), headed by Marcelo Torres (leader of the National University of Colombia), played an important role in the student movement in 1971.

In 1972, the MOIR included electoral competition in its tactics and began its participation in parliamentary and departmental elections, and developed alliances with different political sectors.

In this period, paramilitaries and guerrillas assassinated several party cadres and forced the central leadership to call for a massive withdrawal from the rural areas, where the MOIR was beginning to build peasant agricultural associations.

However, he opposed the formation of the Unitary Party of Workers (CUT), which was the point of convergence of almost all Colombian unionism, considering it an opportunist and liberal centre.

Mosquera's successor and co-founder of the MOIR: Héctor Valencia, ran against with Senator Jesús Bernal Amorocho, who led the bank workers sector of the party.

To complete this episode of factionalism, small groups in Bogotá considered the modern MOIR as a traitor to "Francisco Mosquera Thought" and separated from the party.
