The historic event associated with the "March on Washington" in 1963 is the demand for civil and economic rights for African Americans. Held on August 28, 1963, the march drew over 250,000 participants and featured powerful speeches advocating for racial equality, desegregation, and jobs. One of the most memorable moments was Martin Luther King Jr.'s iconic "I Have a Dream" speech, which articulated his vision for a racially integrated and harmonious America. The event marked a pivotal moment in the Civil Rights Movement, garnering widespread attention and support for legislative changes, eventually contributing to the passage of the Civil Rights Act of 1964.
