Cesar Chavez was an American farmer, union leader, and civil rights activist. He co-founded the National Farm Workers Association, which later became United Farm Workers. His birthday has become a holiday in eight US states.

Chavez was born in Yuma in 1927 as the second of five children of a peasant family. To pay the tax debts, the family sold the farm in 1939 and joined migrant workers to earn a living in Arizona and California. In 1944 he went to the United States Marine Corps. In 1948 he returned to California and married Helen Fabela.

From 1952 he sat down in the Community Service Organization (CSO) for social affairs, where he was supported by Fred Ross. In 1962, Chavez left the CSO to build the National Farm Workers Association (NFWA) with Dolores Huerta. In 1965, the NFWA and the Agricultural Workers Organization Committee (AWOC) joined forces to form the United Farm Workers union, from where he led the struggle for better working conditions in the United States.
