César Chávez was a prominent American labor leader and civil rights activist who co-founded the United Farm Workers (UFW) in 1962. His work aimed to improve the working conditions and rights of farmworkers, many of whom were immigrants, drawing attention to their struggles for better wages, safer working environments, and access to basic human rights. Chávez's commitment to nonviolent protest and grassroots organizing made him a significant figure in the immigrant rights movement and labor rights advocacy.
