African Americans campaign for voting rights in Selma, Alabama, USA, 1965
Even after the passage of the Civil Rights Act of 1964, most African Americans in the southern United States were still unable to vote because of registration requirements such as literacy tests and slow registration processes. In Selma, Alabama the registration office was open only two days a month and could only process 15 registrations for each of these days. This was not nearly enough to register the 15,000 black citizens of voting age in the county.
