Revolutionary Socialist Party (Colombia)

The Revolutionary Socialist Party (Partido Socialista Revolucionario, PSR) was a Colombian political party of Trotskyist tendencies, active primarily during the 1970s and 1980s. The PSR emerged from a split within the Independent Revolutionary Workers Movement (MOIR) in the early 1970s. It advocated for a socialist revolution in Colombia and opposed what it perceived as the reformist and collaborationist tendencies of other left-wing groups.

The PSR engaged in various forms of political activism, including student organizing, labor organizing, and participation in elections. The party sought to build a broad-based movement of workers, peasants, and students to challenge the established political and economic order.

A key aspect of the PSR’s ideology was its adherence to Trotskyism, emphasizing the need for a permanent revolution and international solidarity among the working class. It opposed the Stalinist model of socialism and advocated for democratic socialism.

The party's influence peaked during the 1970s and early 1980s, but it gradually declined in subsequent years. Internal divisions and the changing political landscape in Colombia contributed to its eventual weakening. The PSR's impact on Colombian politics was relatively limited, but it contributed to the broader socialist and revolutionary movements of the time. It is often remembered for its staunch advocacy of Trotskyist principles within the Colombian left. Information on its later activities and ultimate dissolution is limited and somewhat unclear.
