Norway hosted the 1993 ceremony where Nelson Mandela and F.W. de Klerk received the Nobel Peace Prize.
The Nobel Peace Prize is presented in Oslo, Norway, while the other Nobel Prizes are awarded in Stockholm, Sweden. Mandela and de Klerk were jointly awarded the 1993 Peace Prize for their work to peacefully end apartheid and establish the foundations of a democratic South Africa.
The award recognized a negotiation process rather than a single event. Mandela had been released in 1990, and he and de Klerk became central figures in talks that dismantled apartheid laws and prepared the country for universal suffrage. Their cooperation was often tense, but it helped prevent a wider civil conflict.
A frequent mistake is associating every Nobel ceremony with Stockholm. Oslo is the specific exception for the Peace Prize, which is why the 1993 Mandela–de Klerk ceremony took place in Norway.
