Cesar Chavez  was an American labor leader and civil rights activist who co-founded the National Farm Workers Association (later the United Farm Workers union, UFW) in 1962. Originally a Mexican American farm worker, 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.

During his lifetime, Cesar Chavez was one of the few institutions named in his honor, but after his death he became a major historical icon for the Latino community, with many schools, streets, and parks being named after him. He has since become an icon for organized labor and leftist politics, symbolizing support for workers and for Hispanic empowerment based on grass roots organizing. He is also famous for popularizing the slogan “Sí, se puede” (Spanish for “Yes, one can” or, roughly, “Yes, it can be done”), which was adopted as the 2008 campaign slogan of Barack Obama.
