Fifty years ago, on 2 July 1964, American President Lyndon B Johnson signed into law the Civil Rights Act, outlawing discrimination based on race, colour, religion, sex or national origin in public accommodations.
The Voting Rights Act, which ended the systematic disenfranchisement of African-Americans in Southern states, followed the next year. Together, they represent some of the most significant bills to survive the US Congress in the past century.
