Martin Luther King Jr. delivered his famous "I Have a Dream" speech on August 28, 1963, during the March on Washington for Jobs and Freedom. This speech is one of the most iconic moments in the American civil rights movement, where King eloquently expressed his vision for a future where people would be judged by their character rather than their skin color. Delivered from the steps of the Lincoln Memorial, the speech captured the aspirations and frustrations of African Americans seeking equality and justice. King's powerful oratory galvanized public sentiment and became a pivotal moment in the fight against racial segregation and discrimination in the United States.
