Step-by-step explanation:
Dr. Martin Luther King Jr. delivered his iconic "I Have a Dream" speech on August 28, 1963, during the March on Washington for Jobs and Freedom. This event was a massive rally that sought to draw attention to the injustices faced by African Americans and demanded civil and economic rights. King’s speech is celebrated for its profound impact on the civil rights movement and its powerful use of prophetic rhetoric to articulate a vision of racial equality and harmony.
King was involved as the key speaker, and the speech was heard by a large audience of approximately 250,000 people at the Lincoln Memorial in Washington, D.C. The march itself was a coordinated effort between six major civil rights organizations, highlighting the collaborative spirit of the movement. The speech emphasized the necessity of ending racism and was a crucial factor in advancing civil rights legislation.
