What were two of the biggest influences on Dr. Martin Luther King Jr.'s philosophy of "non-violence"?

One significant influence on Dr. King Jr.'s personal philosophy was the life and thought of Mahatma Ghandi, the champion of non-violence in the fight for Indian independence from Britain. During the years he spent at Crozer Theological Seminary in Chester, Pennsylvania, he became acquainted with Gandhi's ideas.

Another major influence was the works and thoughts of contemporay Protestant theologians. He studied for a Ph. D. degree at Boston University. In 1955 he got his title of doctor with a thesis called "A Comparison of the Conceptions of God in the Thinking of Paul Tillich and Henry Nelson Wieman."
