In 1966, Civil Rights pioneer James Meredith set out on The March Against Fear, a walk to prove black citizens no longer needed to fear white people. Soon after beginning, he was ambushed and shot. The march was continued by Dr. Martin Luther King Jr., Stokely Carmichael, and countless others. Weeks later, Meredith had recovered and rejoined the walk, giving history an enduring image of persistence and determination. We talk to historian Ann Bausum about the history and impact of the march.
