Clark was a student at
Tougaloo College, an
historically black college in
Tougaloo, Mississippi, when she became involved with the
civil rights movement. An activist with the
NAACP, she was involved with voter registration efforts. Under the guidance of Medgar Evers and John Salter, Clark founded the
NAACP Youth Council in
North Jackson, Mississippi. While working with the NAACP, she became special assistant to
Medgar Evers,
field secretary for the
NAACP. In 1962 Clark resigned from the NAACP and joined the
Student Nonviolent Coordinating Committee (SNCC) to do voter registration work alongside her then husband,
Bernard Lafayette, in Alabama. This project laid essential groundwork for the
Selma voting rights campaign of 1965. She was eventually named executive secretary of SNCC. She was an organizer in the
Black Power movement, including the
Republic of New Afrika. By early 1973, she returned to Mississippi and worked on a number of other projects including the editorship of the
Jackson Advocate. ==Green Party==
