Which major historical event is associated with the Civil Rights Movement?

The March on Washington for Jobs and Freedom in 1963 is closely associated with the Civil Rights Movement as it was a pivotal event that brought national attention to the struggle for civil rights in the United States. During this march, key figures such as Martin Luther King Jr. delivered impactful speeches, including his famous "I Have a Dream" speech, which called for racial equality and justice. The event highlighted the economic challenges faced by African Americans and advocated for jobs and fair treatment, emphasizing the need for legislative change and social justice. This gathering of over 250,000 people made it one of the largest demonstrations for human rights in United States history and played a crucial role in galvanizing support for subsequent civil rights legislation.

The other historical events listed, while significant in their own right, do not directly reflect the specific aims and achievements of the Civil Rights Movement. The signing of the Declaration of Independence primarily established the United States' independence from British rule, while the establishment of the Bill of Rights focused on individual liberties and legal protections. The end of the Vietnam War marked a different chapter in American history, primarily concerning foreign policy and military engagement rather than civil rights and social justice domestically.
