The Revolutionary Socialist Party (PSRC) was one of the first stable Marxist political parties in Colombia.[1] It is the predecessor to the modern Colombian Communist Party, formed in 1930.
It was founded in 1926 during the Third Worker's Congress, with origins in the National Workers' Confederation, as well as peasant, tenant, and indigenous groups. Its leadership was composed mostly of peasants with intellectuals, workers, and small land owners as well.
In 1927, its first National Convention was held in La Dorada, Caldas. Its entire leadership, being arrested by the police prior to the Convention, ended up meeting in the municipality's prison.
Among its members were María Cano, Tomás Uribe Márquez, Felipe Lleras, Ignacio Torres Giraldo, Gilberto Vieira White, and José Gonzalo Sánchez.
The failure of the banana strike in Ciénaga, Magdalena in 1928 plunged the PSR into a deep crisis that led to its practical division.
On July 17, 1930, the expanded plenary of the party's Central Committee officially renamed the party the Colombian Communist Party, now a member of Communist International. This initiated a campaign of "Bolshevikzation", from which María Cano and Tomás Uribe Márquez would emerge as party leaders.[2]
