The Mexican muralist movement emerged in the early 20th century, primarily during the post-revolutionary period in Mexico. It aimed to promote social and political messages through large-scale murals, often painted on public buildings. Key figures included artists like Diego Rivera, David Alfaro Siqueiros, and José Clemente Orozco, who sought to reflect the struggles and aspirations of the Mexican people. These murals often depicted themes of indigenous culture, social justice, and the history of Mexico. The movement was not only an artistic endeavor but also a means of educating the public and fostering national identity, making art accessible to all citizens.
