On August 28, 1963, protestors descended upon Washington in what was to become one of the defining actions of the civil rights movement. An estimated 250,000 people marched peacefully from the Washington Monument to the Lincoln Memorial, officially in support of President Kennedy’s recent Civil Rights Bill, but also to demand freedom and better working conditions for black people in the South. At the march’s endpoint, Martin Luther King, Jr delivered his “I have a dream” speech, a powerful, sermon-like call for racial equality that, later broadcast on television, went on to inspire millions.
