the region and that certain organizations and types of activism were limited to particular geographies. For instance, in southern Texas where Mexican Americans comprised a significant portion of the population and had a history of electoral participation, the Raza Unida Party started in 1970 by Jose Angel Gutierrez hoped to win elections and mobilize the voting power of Chicanos. RUP thus became the focus of considerable Chicano activism in Texas in the early 1970s. The movement in California took a different shape, less concerned about elections. Chicanos in Los Angeles formed alliances with other oppressed people who identified with the Third World Left and were committed to toppling U.S. imperialism and fighting racism. The Brown Berets, with links to the Black Panther Party, was one manifestation of the multiracial context in Los Angeles. The Chicano Moratorium antiwar protests of 1970 and 1971 also reflected the vibrant collaboration between African Americans, Japanese Americans, American Indians, and white antiwar activists that had developed in Southern California. Chicano student activism also followed particular geographies. MEChA established in Santa Barbara, California, in 1969, united many university and college Mexican American groups under one umbrella organization. MEChA became a multi-state organization, but an examination of the year-by-year expansion shows a continued concentration in California. The Mapping American Social Movements digital project shows maps and charts demonstrating that as the organization added dozens then hundreds of chapters, the vast majority were in California. This should cause scholars to ask what conditions made the state unique, and why Chicano students in other states were less interested in organizing MEChA chapters? Political activism In 1949 and 1950, the American G.I. Forum initiated local "pay your poll tax" drives to register Mexican American voters. Although they were unable to repeal the poll tax, their efforts did bring in new Latino voters who would begin to elect Latino representatives to the Texas House of Representatives and to Congress during the late 1950s and early 1960s. In California, a similar phenomenon took place. When World War II veteran Edward R. Roybal ran for a seat on the Los Angeles City Council, community activists established the Community Service Organization (CSO). The CSO was effective in registering 15,000 new voters in Latino neighborhoods. With this newfound support, Roybal was able to win the 1949 election race against the incumbent councilman and became the first Mexican American since 1886 to win a seat on
