Desmond Tutu will primarily be remembered by posterity for his role as a leader in the struggle against South African apartheid. An Anglican bishop who spoke out courageously against his country's white minority government and its cruel oppression of the black majority, the 1984 Nobel Peace Prize winner was the face of the anti-apartheid movement at a time when most of its leaders -- like future South African President Nelson Mandela -- were imprisoned. His campaign to cause the world to regard the apartheid regime as a moral pariah, not only helped to build support for boycotts of South Africa, but was part of the process that set in motion the events that led to its demise.
