This three-part program traces Chicano heritage and influence in Arizona's history between the 1600s and the 1950s. It begins with a consideration of Mexican immigrants' role in pioneering Arizona's first non-Indigenous settlements, discusses these settlers' conflicts with Indigenous peoples and Anglo settlers, recounts Mexican-American contributions to Arizona's economic growth, chronicles rising racism towards, discrimination against, and segregation of Mexican-Americans, and finally studies Mexican-American work to secure equal rights.
