By 1964 Moses had become co-director of the Council of Federated Organizations (COFO), an umbrella organization for the major civil rights groups working in Mississippi. A major leader with SNCC, he was the main organizer of COFO's Freedom Summer project, which was intended to achieve widespread voter registration of blacks in Mississippi, and ultimately, end racial disfranchisement. They planned education and organizing, and a simplified registration system, to demonstrate African-American desire to vote. Moses was one of the calm leaders who kept the group focused.
