Newsround's Ricky is in South Africa, talking to children there about what Mandela means to them and what kind of nation he leaves behind.
Ricky visited children at a school in Soweto, where Mandela spent much of his younger years, to speak to them about the former leader.
One girl told Ricky that she sees Mandela as a "global icon, partly because he symbolises peace."
South Africa is preparing to say a final goodbye to Nelson Mandela at his funeral this Sunday.
Thousands of people will line the streets once again to pay their final respects to the man who helped to end the racist system of apartheid and unite the country.
The former leader of South Africa passed away last week.
Tributes have been taking place across the world, including a memorial service on Tuesday in Johannesburg, which was attended by lots of world leaders.
