Frederik Willem de Klerk OMG DMS (/də ˈklɜːrk, də ˈklɛərk/ də-KLURK, də-KLAIRK, Afrikaans: [ˈfriədərək ˈvələm də ˈklɛrk]; 18 March 1936 – 11 November 2021) was a South African politician who served as final state president of South Africa from 1989 to 1994 and as deputy president alongside Thabo Mbeki under President Nelson Mandela from 1994 to 1996. As South Africa's last head of state from the era of white-minority rule, he and his government dismantled the apartheid system and introduced universal suffrage. Ideologically a social conservative and an economic liberal, he led the National Party (NP) from 1989 to 1997.
Born in Johannesburg to an influential Afrikaner family, de Klerk studied at Potchefstroom University before pursuing a career in law. Joining the NP, to which he had family ties, he was elected to parliament and sat in the white-minority government of P. W. Botha, holding a succession of ministerial posts. As a minister, he supported and enforced apartheid, a system of racial segregation that privileged white South Africans. After Botha resigned in 1989, de Klerk replaced him, first as leader of the NP and then as State President. Although observers expected him to continue Botha's defence of apartheid, de Klerk decided to end the policy. He was aware that growing ethnic animosity and violence was leading South Africa into a racial civil war. Amid this violence, the state security forces committed widespread human rights abuses and encouraged violence between the Xhosa and Zulu people, although de Klerk later denied sanctioning such actions. He permitted anti-apartheid marches to take place, legalised a range of previously banned anti-apartheid political parties, and freed imprisoned anti-apartheid activists such as Nelson Mandela. He also dismantled South Africa's nuclear weapons program.
