Cesar Estrada Chavez is best known as the founder of one of the organizations that later became the United Farm Workers labor union. In 1962, Chavez founded the National Farm Workers Association. In 1966, this organization merged with the Agricultural Workers Organizing Committee to form United Farm Workers.
As a migrant worker, labor leader and civil rights activist, Cesar Chavez used nonviolent tactics such as strikes, fasts, picketing and marches to publicize the struggle for the rights of farm workers. In 1968, Chavez famously led a boycott of table grapes, mobilizing consumer support to ultimately win a contract with the major grape growers of California. Cesar Chavez is also known for popularizing the slogan "Sí, se puede," or "Yes, it can be done."
