Cesar Chavez was a Mexican American civil rights and labor leader who fought for better working conditions for migrant farm workers. He organized the United Farm Workers union and led a nationwide grape boycott and strikes that lasted for years. Though the workers faced hardships and oppression, their efforts improved wages and rights for migrant laborers. Chavez became a prominent advocate for social justice and remained dedicated to the farm worker cause until his death in 1993, where over 40,000 people mourned the loss of his leadership.
