Mexican muralism
These ideas gained power as a result of the Mexican Revolution, which overthrew the Díaz regime in less than a year. However, there was nearly a decade of fighting among the various factions vying for power. Governments changed frequently with a number of assassinations, including that of Francisco I. Madero who initiated the struggle. It ended in the early 1920s with one-party rule in the hands of the Álvaro Obregón faction, which became the Partido Revolucionario Institucional (PRI). During the Revolution, Atl supported the Carranza faction and promoted the work of Rivera, Orozco and Siqueiros, who would later be the founders of the muralism movement. Through the war and until 1921, Atl continued to paint murals among other activities including teaching the Mexico’s next generation of artists and muralists.
