The implications of Martin Luther King Jr.'s "I Have a Dream" speech were profound for the Civil Rights Movement. Delivered during the 1963 March on Washington, it called for racial equality and an end to discrimination. King's vision of a racially integrated and harmonious society galvanized support nationwide and became a symbol of hope for millions. The speech's powerful language and imagery inspired activism and influenced legislation, notably the Civil Rights Act of 1964 and the Voting Rights Act of 1965. King's message continues to resonate today, representing the ongoing struggle for social justice.
