Final answer:
Nelson Mandela won the Nobel Peace Prize in 1993 for ending apartheid and laying the foundation for democracy in South Africa. He quoted fellow Nobel laureate Archibald MacLeish in his acceptance speech.
Step-by-step explanation:
Nelson Mandela won the Nobel Peace Prize in 1993 for his vital role in the peaceful termination of the apartheid regime, and for laying the foundation for a new democratic South Africa. Sharing this honor with former South African President Frederik Willem de Klerk, Mandela's work also included his efforts to establish a multiracial government in South Africa.
During his acceptance speech, Mandela quoted another Nobel laureate, Archibald MacLeish, drawing from MacLeish's ideas about the significance of creating a world where all individuals can live in freedom. Mandela’s reverence for peace, equality, and human rights echoed the sentiments of many previous Nobel Prize winners, who had also championed these universal values.
