Cesar Chavez and Dolores Huerta Under posters showing Senator Robert Kennedy and Mahatma Gandhi, Chavez and Huerta confer in 1968 during the United Farm Workers’ struggle with grape growers for better wages and working conditions. Chavez, like Martin Luther King, had studied the ideas of Gandhi, who used civil disobedience and nonviolence to gain independence for India. People across the country, including Robert Kennedy, supported the UFW’s grape boycott. Arthur Schatz/Time & Life Pictures/Getty Images.
