The Mexican Revolution (1910–1920) didn't just change politics — it **redefined Mexican art**. The post-revolutionary state (Obregón, Calles) commissioned public murals to forge a **new national identity**. Artists became cultural architects.
Murals became **weapons of critique**: land theft, labor exploitation, foreign (US) corporate control, Church complicity, government corruption. Not decoration — **agitation**.
Zapata, Villa, soldaderas, campesinos elevated to **mythic status**. The Revolution = **popular uprising**, not elite coup. Murals taught history to the illiterate.
Pre-Columbian civilizations (Aztec, Maya, Olmec, Teotihuacan) celebrated as **living heritage**, not ruins. Symbols: maize, eagle/jaguar, calendar stone, Quetzalcoatl. **Vasconcelos' "Cosmic Race" (La Raza Cósmica)** visualized.
Factory hands, miners, braceros, milperos centered — **dignity of labor**. Contrast with Porfirian elitism. Rivera's *Detroit Industry*, *Man at the Crossroads*; Orozco's *The Trench*; Siqueiros' *Portrait of the Bourgeoisie*.
Capitalists as vampires, skeletons, puppeteers. US eagle vs. Mexican eagle. **Siqueiros** pioneered industrial materials (airbrush, pyroxylin) for visceral impact.
Murals in **schools, hospitals, unions, ministries** — free, public, didactic. **Vasconcelos (SEP Minister)** mandated: "Art for the people, by the people." Literacy campaigns used mural imagery.
Broke elite salon monopoly. **Public walls = people's museum**. Fostered **mexicanidad** — pride in mestizo identity, popular culture, resistance history.
+ **Frida Kahlo** (easel, intensely personal) & **Rufino Tamayo** (universal, non-political).
Mexican Muralism became the **first major 20th-century art movement from the Global South** — influencing WPA murals (US), Latin American social realism, Chicano movement, street art globally. The Revolution gave them the **wall, the audience, and the mandate**.
