On May 25, 1961, Bruce Davidson joined a group of Freedom Riders traveling by bus from Montgomery, Alabama, to Jackson, Mississippi. The actions of the Riders tested federal laws permitting integrated interstate bus travel. These historic episodes, which ended in violence and arrests, marked the beginning of Davidson’s exploration into the heart of the civil rights movement in the United States during the years 1961–1965. Pictured here, the arrest of a demonstrator in Alabama, Birmingham, 1963.
