Prior to the Chicano Movement of the late 60s and early 70s, the young Mexican-American community in the United States was fighting for equal treatment in American society. This climaxed in the East LA walk-outs of 1968 when Mexican-American High School Students throughout the Los Angeles Unified School District took part in a series protests against unequal treatment in LA high schools. The protests rippled through the United States and caused a number of other student-led demonstrations throughout Southwest United States.
