Nelson Mandela, the former political prisoner who became the first president of a post-apartheid South Africa and whose heroic life and towering moral stature made him one of history's most influential statesmen, died Dec. 5, the government announced. He was 95.

The death was announced in a televised address by President Jacob Zuma, who added, "we've lost our greatest son." No cause was provided.

To a country torn apart by racial divisions, Mandela became its most potent symbol of national unity, using the power of forgiveness and reconciliation to heal deep-rooted wounds and usher in a new era of peace after decades of conflict between blacks and whites. To a continent rife with leaders who cling to power for life, Mandela became a role model for democracy, stepping down from the presidency after one term and holding out the promise of a new Africa.
