This person: Nelson Mandela was against the APARTHEID in his country South Africa.
The Apartheid consisted in removing black people from white people.
Nelson Mandela protested against racism, he was and he still is a pacifist leader.
Now he is the President of South Africa.
Nelson Mandela was put in jail and his people dedicated this song. I love it.
*Now, at the cinemas you can see the film "Invictus", a movie about Nelson Mandela and about rugby. The movie is directed by Clint Eastwood.
