The March on Washington was the largest demonstration ever held in support of improved rights for African Americans. More than 250,000 people from across the U.S. gathered in Washington, D.C. for the march. It was here that Martin Luther King, Jr. gave his famous speech "I Have A Dream." In this speech, Dr. King spoke of a time when differences over race would be forgotten and all Americans would enjoy the same freedoms and rights. This march led to many important laws that protected the rights of African Americans.
