Despite early success at Katz Drug Store, the struggle to end segregation continued. Sit-ins, marches, and other forms of protest took place until 1964. Always nonviolent, these acts of civil disobedience included negotiations with city leaders and owners of segregated establishments before direct action was taken. This tactic led to both the success of the movement and prevented any outbreaks of violence. Even though Oklahoma City was not fully integrated when the Civil Rights Act of 1964 became law, great progress had been made.
