This thesis examines the Maricopa County Organizing Project (MCOP or the Project) which was founded in 1977 in Maricopa County, Arizona. The MCOP is believed to be the first organization to hold an agricultural strike that consisted of entirely undocumented workers. The Project was founded by Mexican American activists who believed that undocumented and documented workers shared the same human rights and should unite against growers thereby increasing their bargaining power. Its work was significant because it was the first organization to actively target undocumented workers and to advocate for their concerns using human rights as the justification. This thesis uses primary sources from the Maricopa County Organizing Project’s Records, held at Arizona State University, Tempe, as well as newspapers, court cases and congressional hearings to argue that the MCOP achieved some success in Arizona because of its inclusion and active recruitment of undocumented members and that it continued in a long tradition of Mexican American civil rights organizing.
