In the wake of the Mexican Revolution of 1910, the artistic endeavors of a group of painters known as the Mexican Muralists evolved from the pre-Columbian roots of the artists, as well as a desire to address the political and social transformation of the modern age. The most influential members of this group — Diego Rivera, José Clemente Orozco, and David Alfaro Siqueiros — often used large-scale mural paintings in order to convey their messages, as public murals could be viewed by the general public, regardless of social class. This lecture analyzes the work of the three artists in the context of how they used public, monumental art to promote social ideals and celebrate indigenous culture.
