Mandela was co-winner of the Nobel Peace Prize along with F.W. de Klerk, the last president of the apartheid government, for his efforts at bringing about a peaceful transition in South Africa.
He had emerged from prison in 1990 advocating forgiveness and reconciliation, and became president after South Africa's first all-race elections, in 1994. He served one five-year term.
The burial ended 10 days of mourning ceremonies that included a massive stadium memorial in Johannesburg and three days during which Mandela's body lay in state in the capital, Pretoria.
While South Africa faces many problems, including crime, unemployment and economic inequality, Mandela is seen by many compatriots as the father of their nation and around the world as an example of the healing power of reconciliation.
