Today, tens of thousands of people gathered near the Lincoln Memorial on the National Mall to celebrate the 50th anniversary of the March on Washington. Those gathered at the Realize the Dream March and Rally, organized by the National Action Network, heard from many speakers from the civil rights movement, as well as leaders in politics, education and social issues.

The Rev. Al Sharpton, one of the event’s organizers, called for the nation to give young people “dreams again.”

Rep. John Lewis, the only surviving speaker from the 1963 March on Washington, delivered an impassioned speech, saying he “gave a little blood on that bridge in Selma, Alabama for the right to vote. I am not going to stand by and let the Supreme Court take the right to vote away from us.”

Martin Luther King III, one of Martin Luther King Jr.’s four children, said his father’s dream has not yet been realized.

Myrlie Evers-Williams, civil rights activist and wife of the late Medgar Evers, called for the crowd to embrace the phrase “Stand Your Ground” and do just that in the face of discriminatory laws.

House Minority Leader Nancy Pelosi, who attended the original March on Washington, said King would “want us to be fighting for voting rights.”
