人民連合
The MAPU/OC aimed at forming a "third proletarian party" in Chile, supporting cooperation with the Communist Party of Chile and the Socialist Party. It adhered to the more “moderate”, legalistic tendency of Unidad Popular, like the Communist Party and Radicals. It regarded the formation of the government of Salvador Allende as the principal victory for people and democracy and distanced itself from more extremist left-wing groups like MIR.
