The National Party, also known as the Nationalist Party, was a political party in South Africa from 1914 to 1997, which was responsible for the implementation of apartheid rule. The party was an Afrikaner ethnic nationalist party, which initially promoted the interests of Afrikaners but later became a stalwart promoter and enactor of white supremacy, for which it is best known. It first became the governing party of the country in 1924. It merged with its rival, the SAP, during the Great Depression, and a splinter faction became the official opposition during World War II and returned to power. With the National Party governing South Africa from 4 June 1948 until 9 May 1994, the country for the bulk of this time was only a de jure or partial democracy, as from 1958 onwards non-white people were barred from voting. In 1990, it began to style itself as simply a South African civic nationalist party, and after the fall of apartheid in 1994, attempted to become a moderate conservative one. The party's reputation was damaged irreparably by perpetrating apartheid, and it rebranded itself as the New National Party in 1997 before eventually dissolving in 2005.
