Describe the activism that started after WWII that led to court victories like Mendez v. Westminster and Perez v. Sharp as well as the rise of the GI Forum and the rise of Henry B. Gonzalez and Edward Roybal.

Mostly because of xenophobia in USA, Mexican American veterans gathered in Texas to arrange and put together a civil rights organization able to ensure and anchor benefits undertaken by the Servicemen's Readjustment Act of 1944 aka G. I. Bill of Rights,

to push for equal treatment regardless of ethnicity or racial stereotypes.

The moden Civil Rights Era is remembered to begin with the Rosa Parks incident and many other strifes for social justice; The Chicano Movement emerged from that era, and the activism that encouraged those victories was led by Dr. Hector P. Garcia, Ivonne Carillo and Anjel Gonzáles as founders in order to achieve Mexican American empowerment but it extended to Hispanic Americans and Latinos in general.
