The 1975 Voting Rights Act Extension and Expansion extended the existing amendments of the 1965 Voting Rights Act and made permanent provisions such as the ban on discriminatory voting tools such as literacy tests and poll tax as well as expanding the Act to include protection for language minorities, one being Spanish speakers. The Act was made in response to claims of voting discrimination against Chicanos, also referred to as Mexican Americans, in Texas. I examine the effects of the 1975 Voting Rights Act Extension and Expansion on the Chicano community. To do this, I employed a political and social history approach to fully understand all parts of the impact of the Act on Chicanos. I referred to government documents including the 1975 Act, relevant court cases, and other bills introduced on the topic in more recent years, testimonies in support of the Act from individuals such as Representative Barbara Jordan and Chicano activist Modesto Rodriguez, as well as oral histories from people like John Treviño Jr., the first Chicano to serve on the Austin City Council, and Brown Beret Susana Almanza. Chicanos are a historically underrepresented group in the United States. Whether it is due to stereotyping of Mexican Americans or negative attitudes toward Spanish speakers, Chicano voices have remained unheard. My work seeks to bring representation to a group oppressed and erased from history. Looking at the impact of the 1975 Act on Chicanos, there is clear evidence of a significant increase in political participation from Chicanos in voters and political candidates, increased acceptance and awareness of bilingual education, and a continued need for Chicano activists working towards the progression of Chicano civil rights.
