David Alfaro Siqueiros is best remembered as one of Los Tres Grandes, along with Diego Rivera and Jose Clemente Orozco. They pioneered the use of murals to tell epic stories of poverty, rebellion, politics, and the troubled history of their native Mexico. Influenced by Marxism in its treatment of class struggle, Siqueiros believed that public murals were a powerful way to allow the masses access to his artwork and political messages. Tres Grandes, among many other artists, were part of the revolutionary change in Mexico. The Tres Grandes were the products of the "Porfiriato", the pre-revolutionary society that flourished under the 30-year dictatorship of Porfirio Diaz. The Diaz administration collapsed from within in 1911 and he fled to Europe. The Mexican Revolution had begun just a year earlier, and the art world had produced muralism as we know it today. The murals represented the social ideas of the revolution. Mexican muralists have painted all over the world, impacting both Mexicans and non-Mexicans. Siqueiros stated that the purpose of the mural was to "address the indigenous races humiliated for centuries; the officers made executioners by their officers, the peasants and workers scourged by the rich." Siqueiros believed that "art should no longer be the expression of individual satisfaction as it is today, but should aim to become a combative educational art for all." Siqueiros had a great influence on other artists. Mexican muralism is considered the only "genuine" Latin American art of the 20th century. Muralism has played a primary role in the development of a national Mexican art that embraces its native Indian indigenous roots and educates the poor masses of the people. In many ways,... at the center of the card... Humanity." He was so immensely esteemed that even President Luis Echeverria was present when the mural was inaugurated on December 15, 1971. Siqueiros was diagnosed with cancer in 1973 and died in 1974 in Cuernavaca. Fellow artist, José Revueltas, described it as "a great mural of Mexico" that was "as titanic as his painting". 20052.
