The Chicano Art Movement represents attempts by Mexican-American artists to establish a unique artistic identity in the United States.
 Much of the art and the artists creating Chicano Art were heavily influenced by Chicano Movement (El Movimiento) which began in the 1960s.
 Chicano art was influenced by post-Mexican Revolution ideologies, pre-Columbian art, European painting techniques and Mexican-American social, political and cultural issues.
 The movement worked to resist and challenge dominant social norms and stereotypes for cultural autonomy and self-determination.
 Some issues the movement focused on were awareness of collective history and culture, restoration of land grants, and equal opportunity for social mobility.
 Throughout the movement and beyond, Chicanos have used art to express their cultural values, as protest or for aesthetic value.
 The art has evolved over time to not only illustrate current struggles and social issues, but also to continue to inform Chicano youth and unify around their culture and histories.
 Chicano art is not just Mexican-American artwork: it is a public forum that emphasizes otherwise "invisible" histories and people is a unique form of American art.
