Diego Rivera with José Chávez Morado, Xavier Guerrero, David Alfaro Siqueiros, and Enrique González Rojo at a Mexican Communist Party event

The Mexican Communist Party, founded by Rivera and Siqueiros, grew out of the Syndicate of Painters, Sculptors, Workers, and Peasants. On their working days, they always came up with strategies for social policies that would benefit the people of Mexico.
