The March on Washington for Jobs and Freedom was a large political rally that took place in Washington, D.C. on August 28, 1963. Martin Luther King, Jr. delivered his historic "I Have a Dream" speech advocating racial harmony at the Lincoln Memorial during the march.
The march was organized by a group of civil rights, labor, and religious organizations, under the theme "jobs, and freedom." Estimates of the number of participants varied from 200,000 (police) to over 300,000 (leaders of the march). About 80% of the marchers were African American and 20% white and other ethnic groups.
The march is widely credited as helping to pass the Civil Rights Act (1964) and the National Voting Rights Act (1965).
