Born in Yuma, Arizona to a Mexican American family, in early life Chavez worked as a manual laborer and spent two years in the United States Navy. Relocating to California, where he married, he got involved in the Community Service Organization (CSO), through which he helped laborers register to vote. In 1959, he became the CSO's national director, a position based in Los Angeles. In 1962 he left the CSO to co-found the UFW. Chavez became the best known Latino American civil rights activist, and was strongly promoted by the American labor movement, which was eager to enroll Hispanic members. His public-relations approach to unionism and aggressive but nonviolent tactics made the farm workers' struggle a moral cause with nationwide support. By the late 1970s, his tactics had forced growers to recognize the UFW as the bargaining agent for 50,000 field workers in California and Florida.
