Who said ''Free at last free at last thank god almighty I am free at last?

The phrase "Free at last! Free at last! Thank God Almighty, I am free at last!" was famously spoken by Dr. Martin Luther King Jr. during his "I Have a Dream" speech delivered at the Lincoln Memorial in Washington, D.C., on August 28, 1963. This powerful line encapsulated the hope for freedom and equality for African Americans and was a pivotal moment in the Civil Rights Movement.
