During the Napoleonic Wars, the Cape Colony was annexed by the British and officially became their colony in 1815. Britain encouraged settlers to the Cape, and in particular, sponsored the 1820 Settlers to farm in the disputed area between the colony and the Xhosa in what is now the Eastern Cape. The changing image of the Cape from Dutch to British excluded the Dutch farmers in the area, the Boers who in the 1820s started their Great Trek to the northern areas of modern South Africa. This period also marked the rise in power of the Zulu under their king Shaka Zulu. Subsequently, several conflicts arose between the British, Boers and Zulus, which led to the Zulu defeat and the ultimate Boer defeat in the Second Anglo-Boer War. However, the Treaty of Vereeniging established the framework of South African limited independence as the Union of South Africa.

A referendum on ending apartheid was held in South Africa on 17 March 1992. The referendum was limited to white South African voters, who were asked whether or not they supported the negotiated reforms begun by State President F. W. de Klerk two years earlier, in which he proposed to end the apartheid system that had been implemented since 1948. The result of the election was a large victory for the "yes" side, which ultimately resulted in apartheid being lifted. Universal suffrage was introduced two years later.

South Africa since 1994 transitioned from the system of apartheid to one of majority rule. The election of 1994 resulted in a change in government with the African National Congress (ANC) coming to power. The ANC retained power after subsequent elections in 1999, 2004, 2009 and 2014. Children born during this period are known as the born-free generation, and those aged eighteen or older, were able to vote for the first time in 2014.

Apartheid was a system of institutionalised racial segregation that existed in South Africa and South West Africa from 1948 until the early 1990s. Apartheid was characterised by an authoritarian political culture based on baasskap, which ensured that South Africa was dominated politically, socially, and economically by the nation's minority white population. According to this system of social stratification, white citizens had the highest status, followed by Asians and Coloureds, then black Africans. The economic legacy and social effects of apartheid continue to the present day.

The Bechuanaland Protectorate was a protectorate established on 31 March 1885, by the United Kingdom of Great Britain and Ireland in Southern Africa. It became the Republic of Botswana on 30 September 1966.

The Cape Qualified Franchise was the system of non-racial franchise that was adhered to in the Cape Colony, and in the Cape Province in the early years of the Union of South Africa. Qualifications for the right to vote at parliamentary elections were applied equally to all men, regardless of race.

During World War II, many South Africans saw military service. The Union of South Africa participated with other British Commonwealth forces in battles in North Africa against Erwin Rommel and his Afrika Korps, and many South African pilots joined the Royal Air Force and fought against the Axis powers in the European theatre.

The National Convention, also known as the Convention on the Closer Union of South Africa or the Closer Union Convention, was a constitutional convention held between 1908 and 1909 in Durban, Cape Town and Bloemfontein. The convention led to the adoption of the South Africa Act by the British Parliament and thus to the creation of the Union of South Africa. The four colonies of the area that would become South Africa - the Cape Colony, Natal Colony, the Orange River Colony and the Transvaal Colony - were represented at the convention, along with a delegation from Rhodesia. There were 33 delegates in total, with the Cape being represented by 12, the Transvaal eight, the Orange River five, Natal five, and Rhodesia three. The convention was held behind closed doors, in the fear that a public affair would lead delegates to refuse compromising on contentious areas of disagreement. All the delegates were white men, a third of them were farmers, ten were lawyers, and some were academics. Two-thirds had fought on either side of the Second Boer War.

The National Party, also known as the Nationalist Party, was a political party in South Africa founded in 1914 and disbanded in 1997. The party was an Afrikaner ethnic nationalist party that promoted Afrikaner interests in South Africa. However in 1994 it became a South African civic nationalist party seeking to represent all South Africans. It first became the governing party of the country in 1924. It was an opposition party during World War II but it returned to power and was again in the government from 4 June 1948 until 9 May 1994.

The Orange River Colony was the British colony created after Britain first occupied (1900) and then annexed (1902) the independent Orange Free State in the Second Boer War. The colony ceased to exist in 1910, when it was absorbed into the Union of South Africa as Orange Free State Province.

The South Africa Act 1909 was an Act of the British Parliament which created the Union of South Africa from the British colonies of the Cape of Good Hope, Natal, Orange River Colony, and Transvaal. The Act also made provisions for admitting Rhodesia as a fifth province of the Union in the future, but Rhodesian colonists rejected this option in a referendum held in 1922. The South Africa Act was the third major piece of legislation passed by the Parliament of the United Kingdom with the intent of uniting various British colonies and granting them some degree of autonomy. Earlier, the British North America Act, 1867 had united three colonies and the Commonwealth of Australia Constitution Act, 1900 had united the Australian colonies.

The Union of South Africa is the historical predecessor to the present-day Republic of South Africa. It came into being on 31 May 1910 with the unification of the Cape Colony, the Natal Colony, the Transvaal, and the Orange River Colony. It included the territories that were formerly a part of the South African Republic and the Orange Free State.
