Muralism is an artistic movement that emphasizes large-scale murals, often painted on walls, to convey social and political messages. Originating in Mexico in the early 20th century, it aimed to make art accessible to the public and reflect the struggles and aspirations of the people. Prominent figures like Diego Rivera and David Alfaro Siqueiros played crucial roles in this movement, using their art to address issues such as class struggle and national identity. The murals often depict historical events, cultural heritage, and social justice themes, transforming public spaces into vibrant storytelling canvases. Muralism not only beautifies urban environments but also fosters community engagement and dialogue, making it a powerful tool for social change.
