Final answer:
The 1965 Delano grape strike aimed to improve conditions for migrant farmworkers, leading to a nationwide boycott and the eventual recognition of the United Farm Workers by California grape growers.
Step-by-step explanation:
The purpose of the 1965 Delano grape strike led by Cesar Chavez was to draw national attention to the plight of migrant farmworkers and to demand better working conditions and pay. Chavez, along with Dolores Huerta and the United Farm Workers (UFW), joined a strike initiated by Filipino grape pickers and called for a national boycott of grapes. This strategy was not just about labor rights; it targeted consumer behavior to exert pressure on grape growers. Their nonviolent methods were inspired by Gandhi and the African American civil rights movement, leading to a 300-mile march to Sacramento and a successful nationwide boycott that eventually brought about improved conditions and recognition of the UFW by grape growers in California.
