During the 1960s, East Los Angeles became the center of the Chicano Movement, or Movimiento, the Mexican-American civil rights struggle. Thousands of Chicanos marched in protests, won reforms and changed America forever. But two generations later, that history is being forgotten. California schools don’t teach it and many immigrant parents don’t know it. A group of Chicano artists is trying to bring that history back to life by bringing a special theater program to an East L.A. school for youth at risk.
