"American civil rights leader, Letter from a Birmingham Jail There comes a time when the cup of endurance runs over, and men are no longer willing to be plunged into an abyss of injustice where they experience the blackness of corroding despair."
Martin Luther King Jr. was an American Baptist minister and civil rights leader who led campaigns against racial segregation in the United States. His leadership of nonviolent protest helped secure major civil rights legislation in the 1960s.
