The United Farm Workers of America, or more commonly just United Farm Workers (UFW), is a labor union for farmworkers in the United States. It originated from the merger of two workers' rights organizations, the Agricultural Workers Organizing Committee (AWOC) led by organizer Larry Itliong, and the National Farm Workers Association (NFWA) led by César Chávez and Dolores Huerta. They became allied and transformed from workers' rights organizations into a union as a result of a series of strikes in 1965, when the mostly Filipino farmworkers of the AWOC in Delano, California initiated a grape strike, and the NFWA went on strike in support. As a result of the commonality in goals and methods, the NFWA and the AWOC formed the United Farm Workers Organizing Committee on August 22, 1966.This organization was accepted into the AFL-CIO in 1972 and changed its name to the United Farm workers Union.
