P. W. Botha, South African soldier and politician, State President of South Africa (born 1916)

Pieter Willem Botha, was a South African politician who served as the last Prime Minister of South Africa from 1978 to 1984 and as the first executive State President of South Africa from 1984 until his resignation in 1989. Nicknamed 'Die Groot Krokodil' due to his tough political stance, he was considered the final hardline leader of South Africa during the apartheid era.

The state president of the Republic of South Africa was the head of state of South Africa from 1961 to 1994. The office was established when the country became a republic on 31 May 1961, outside the Commonwealth of Nations, and Queen Elizabeth II ceased to be Queen of South Africa. The position of Governor-General of South Africa was accordingly abolished. From 1961 to 1984, the post was largely ceremonial. After constitutional reforms enacted in 1983 and taking effect in 1984, the State President became an executive post, and its holder was both head of state and head of government.
