Following the closure of the Bracero program, domestic farmworkers began to organize again because "growers could not longer maintain the peonage system" with the end of imported laborers from Mexico. Labor organizing formed part of the Chicano Movement via the struggle of farmworkers against depressed wages and working conditions. César Chávez began organizing Chicano farmworkers in the early 1960s, first through the National Farm Workers Association (NFWA) and then merging the association with the Agricultural Workers Organizing Committee (AWOC), an organization of mainly Filipino workers, to form the United Farm Workers. The labor organizing of Chávez was central to the expansion of unionization throughout the United States and inspired the Farm Labor Organizing Committee (FLOC), under the leadership of Baldemar Velásquez, which continues today. Farmworkers collaborated with local Chicano organizations, such as in Santa Paula, California, where farmworkers attended Brown Berets meetings in the 1970s and Chicano youth organized to improve working conditions and initiate an urban renewal project on the eastside of the city.
