Nelson Mandela death: Apartheid - 46 years in 90 seconds
Before he became president and elder statesman, Nelson Mandela was the highest-profile figure in South Africa's struggle against apartheid.
But what was apartheid? Many millions of children and young adults have only known a world without it.
While it was in place, though, South African apartheid saw a raft of laws used to rigidly - and often brutally - enforce the separation of whites and blacks.
It led to international isolation and civil conflict, but eventually crumbled after Nelson Mandela was freed from 27 years in prison.
The BBC's Adam Blenford recaps decades of apartheid in 90 seconds, and Nelson Mandela's central role in its defeat.
