Meredith continued his education, focusing on political science, at the University of Ibadan in Nigeria. He returned to the United States in 1965. He attended law school through a scholarship at Columbia University and earned an LL.B (law degree) in 1968.
In 1966, Meredith organized and led a solo, personal March Against Fear for 220 miles from Memphis, Tennessee, to Jackson, Mississippi, beginning on June 6, 1966. Inviting only black men to join him, he wanted to highlight continuing racial oppression in the Mississippi Delta, as well as to encourage blacks to register and vote following passage of the federal Voting Rights Act of 1965, which authorized federal oversight and enforcement of rights. Governor Paul Johnson promised to allow the march and provide State Highway Police protection. Meredith wanted blacks in Mississippi to overcome fear of violence.
