Inaugural Addres
by Nelson Mandela (excerpt)
We have triumphed in the effort to implant hope in the breasts of the millions of our people. We enter into a covenant that we
shall build the society in which all South Africans, both black and white, will be able to walk tall, without any fear in their hearts,
assured of their inalienable right to human dignity-a rainbow nation at peace with itself and the world.
We dedicate this day to all the heroes and heroines in this country and the rest of the world who sacrificed in many ways and
surrendered their lives so that we could be free.
Their dreams have become reality. Freedom is their reward.
We are both humbled and elevated by the honour and privilege that you, the people of South Africa, have bestowed on us, as
the first President of a united, democratic, non-racial and non-sexist South Africa to lead our country out of the valley of
darkness.
We understand it, still, that there is no easy road to freedom.
We know it well that none of us acting alone can achieve success.
We must therefore act together as a united people, for national reconciliation, for nation building, for the birth of a new world.
