Thousands converged Saturday on the National Mall in D.C. for the 60th anniversary of Reverend Martin Luther King Jr.’s famous March on Washington.

King is pictured here during that day when he made his historic “I Have a Dream” speech.

“We have made progress, over the last 60 years, since Dr. King led the March on Washington,” said Alphonso David, president and CEO of the Global Black Economic Forum. “Have we reached the mountaintop? Not by a long shot.”

The event was convened by the Kings’ Drum Major Institute and the National Action Network.

A host of Black civil rights leaders and a multiracial, interfaith coalition of allies rallied attendees on the same spot where as many as 250,000 gathered in 1963 for what is still considered one of the greatest and most consequential racial justice and equality demonstrations in U.S. history.

Reverend Al Sharpton promised more demonstrations to push back against injustices, new and old.

Saturday’s gathering was a precursor to the actual anniversary of the August 28th, 1963 March on Washington.

All of King’s children have been invited to meet with U.S. President Joe Biden at the White House tomorrow.
