The famous "I Have a Dream" speech at the Lincoln Memorial was written by Martin Luther King Jr.. Delivered during the 1963 March on Washington for Jobs and Freedom, this monumental address called for an end to racism and economic injustice in the United States. King emphasized his vision of a racially integrated and harmonious society, resonating with the aspirations of millions. His powerful rhetoric and ability to articulate the struggles of African Americans made this speech a defining moment in the Civil Rights Movement, inspiring generations to continue the fight for equality and justice.
