* The Mexican American Youth Organization (MAYO) was founded in 1967 by José Angel Gutierrez and other Mexican American college students in San Antonio. It concentrated on civil rights and political activity. In the period 1967-1969, it played a leading role in various school walkouts. MAYO took the initiative in the formation of La Raza Unida party in Texas, an independent Chicano political party that functioned in the Southwest during the late 1960s and early 1970s.
