The famous Civil Rights leader who delivered the "I Have a Dream" speech in 1963 was Dr. Martin Luther King Jr. This iconic speech was delivered during the March on Washington for Jobs and Freedom, where more than 250,000 people gathered to advocate for civil and economic rights for African Americans. King's powerful oration emphasized his dream of a racially integrated and harmonious America, where all people would be judged by their character rather than the color of their skin. This pivotal moment played a key role in the Civil Rights Movement, galvanizing support and highlighting the struggle against racial injustice.
