1948 South African general election in the context of "Internal resistance to apartheid"

The African National Congress (ANC) is a political party in South Africa. It originated as a liberation movement known for its opposition to apartheid and has governed the country since 1994, when the first post-apartheid election resulted in Nelson Mandela being elected as President of South Africa. Cyril Ramaphosa, the incumbent national president, has served as president of the ANC since 18 December 2017.

Founded on 8 January 1912 in Bloemfontein as the South African Native National Congress, the organisation was formed to advocate for the rights of black South Africans. When the National Party government came to power in 1948, the ANC's central purpose became to oppose the new government's policy of institutionalised apartheid. To this end, its methods and means of organisation shifted; its adoption of the techniques of mass politics, and the swelling of its membership, culminated in the Defiance Campaign of civil disobedience in 1952–53. The ANC was banned by the South African government between April 1960 – shortly after the Sharpeville massacre – and February 1990. During this period, despite periodic attempts to revive its domestic political underground, the ANC was forced into exile by increasing state repression, which saw many of its leaders imprisoned on Robben Island. Headquartered in Lusaka, Zambia, the exiled ANC dedicated much of its attention to a campaign of sabotage and guerrilla warfare against the apartheid state, carried out under its military wing, uMkhonto weSizwe, which was founded in 1961 in partnership with the South African Communist Party (SACP). The ANC was condemned as a terrorist organisation by the governments of South Africa, the United States, and the United Kingdom. However, it positioned itself as a key player in the negotiations to end apartheid, which began in earnest after the ban was repealed in 1990. For much of that time, the ANC leadership, along with many of its most active members, operated from abroad. After the Soweto Uprising of 1976, the ANC remained committed to achieving its objectives through armed struggle. These circumstances significantly shaped the ANC during its years in exile.

The National Party (Afrikaans: Nasionale Party, NP), 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 South African Party (SAP), during the 1929-1939 Great Depression, and a splinter faction, the Re-United National Party became the official opposition during World War II and won power in 1948. 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.

Following the 1948 general election, the party as the governing party of South Africa began implementing its policy of racial segregation, known as apartheid (the Afrikaans term for "separateness"). Although White-minority rule and racial segregation were already in existence in South Africa with non-Whites not having voting rights and efforts made to encourage segregation, apartheid intensified the segregation with stern penalties for non-Whites entering into areas designated for Whites-only without having a pass to permit them to do so (known as the pass laws), interracial marriage and sexual relationships were illegal and punishable offences. Black people faced significant restrictions on property rights. After South Africa was condemned by the British Commonwealth for its policies of apartheid, the NP-led government had South Africa leave the Commonwealth, abandon its monarchy led by the British monarch and become an independent republic. The party's system of apartheid was officially labelled a crime against humanity by the United Nations General Assembly on 16 December 1966.

South Africa under apartheid was subjected to a variety of international boycotts, including on sporting contacts. There was some debate about whether the aim of the boycott was to oppose segregation in sport or apartheid in general, with the latter view prevailing in later decades. While the National Party introduced apartheid in 1948, it added sport-specific restrictions from the late 1950s, on interracial sport within South Africa and international travel by nonwhite athletes. The international federations (IFs) governing various sports began to sanction South Africa, both in response to the new restrictions and in reflection of the broader anti-racism of national federations in newly independent postcolonial states. By the early 1970s, South African national teams were excluded from most Olympic sports, although South Africans competed in individual events in some, mainly professional, sports through the 1980s. Although from the mid-1970s the National Party relaxed the application of segregation provisions in relation to sport, this failed to alleviate the boycott, which continued until the end of apartheid.

The Herenigde Nasionale Party (English: Reunited National Party; HNP) was an Afrikaner nationalist and conservative political party in South Africa. It was founded in 1940 from the merger of the Purified National Party (Gesuiwerde Nasionale Party, GNP) led by future prime minister D. F. Malan and a faction of the United Party (UP) led by J. B. M. Hertzog, who split from the party and resigned as prime minister of South Africa in opposition to the country's support for the Allies during World War II. The HNP won a plurality of seats at the 1948 general election despite losing the popular vote to the UP and formed a coalition government with the Afrikaner Party (AP), which it merged with to form the National Party (NP) in 1951; the NP name had previously been used by the party Hertzog merged into the UP.
