Watch A Principled Man: Rev. Leon Sullivan

He was called "The Lion from Zion," a reference to his years in the pulpit and a metaphor for a man whose roar echoed across continents. A towering figure in America's civil rights movement, Sullivan dedicated his life to stalking injustice and oppression. A mentor of Martin Luther King, the Sullivan Principles helped to free Nelson Mandela and South Africa from the chains of apartheid.
