Rebels with La Causa explores the expansive production and creative impact of the Royal Chicano Air Force (RCAF), one of the Chicano Movement’s most prolific and impactful artist collectives. Beginning in 1970 at Sacramento State, the group produced individual artworks and group murals, as well as posters for educational, cultural, and political activities. The RCAF’s transformation into a broader collective not only initiated an explosion of Chicano art exhibitions, literary events, performances, and community celebrations, but expanded civic and political engagement. While RCAF posters served as announcements for these wide-ranging activities, their multicultural aesthetics, subject matter, and strategic humor redefined Chicana/o art, as well as the history of art and activism in the United States.
