The March on Washington for Jobs and Freedom was held on August 28, 1963. With over 200,000 participants, the march was organized to pressure the U.S. government into passing long-needed, robust civil rights legislation. Although its most famous moment was Martin Luther King Jr.'s "I Have a Dream" speech, thousands of ordinary people also took to the streets to demand equal rights—and America began to take notice. Still, injustice, and the struggle against it, continues to the present day. Library of Congress, photo by Warren K. Leffler
