The March on Washington for Jobs and Freedom, which took place on August 28, 1963, was a pivotal moment in the civil rights movement. It brought national attention to the issue of civil rights and helped to build momentum for the passage of the Civil Rights Act of 1964. The peaceful protest, where Martin Luther King Jr. delivered his famous "I Have a Dream" speech, played a significant role in mobilizing public support for the legislation, which was signed into law by President Lyndon B. Johnson on July 2, 1964. The Civil Rights Act of 1964 outlawed discrimination based on race, color, religion, sex, or national origin, and was a major victory for the civil rights movement.
