Clarence Hall, Jr. was a local activist and Issaquena County native who made some of the first inquiries into an NAACP law suit against the Issaquena County Board of Education for the suspension of students wearing pro-SNCC materials in 1965. Following the ruling in Blackwell v. Issaquena that black students in Issaquena and Sharkey Counties could not be prohibited from attending white schools, Hall became a leader in registering black students for historically white public schools.
Hall was also active in a number of local chapters of important rights organizations, including the Delta Ministry. Hall was particularly vital as an administrative assistant to the Freedom City project beginning in 1966, an affordable housing initiative that eventually failed. Hall served as a key mover in the implementing the Comprehensive Employment and Training Act (CETA) and Head Start legislation.
In 1968, Hall ran an unsuccessful campaign for U.S. Congress on the Democratic ticket.
