Washington, D.C. (WSYR-TV/CNN) - Thousands gathered Saturday at the National Mall to mark 50 years since the historic March on Washington.
At the 1963 event, Rev. Martin Luther King, Jr. gave his "I Have a Dream" speech.
His son addressed the crowd on Saturday.
"We must embrace love and hold on to that powerful spiritual which inspired my father's generation and inspires us today," said Martin Luther King III.
"We ain't gonna let nobody turn us around, we gonna keep walking, keep on talking, keep on voting, keep on job building, keep on educating, keep on mentoring, keep on community building, keep on ending violence, keep on creating peace. Ain't going to let nobody turn us around."
Saturday's event is the first of two rallies to mark the anniversary.
President Barack Obama headlines another event Wednesday, the exact anniversary of the March on Washington, where MLK delivered the now-famous speech at the Lincoln Memorial.
The Wednesday event will include a longer march through Washington and speeches by Obama and former presidents Bill Clinton and Jimmy Carter.
