The Cape Colony, also known as the Cape of Good Hope, was a British colony in present-day South Africa named after the Cape of Good Hope. It existed from 1795 to 1802, and again from 1806 to 1910, when it united with three other colonies to form the Union of South Africa, then became the Cape Province, which existed even after 1961, when South Africa had become a republic, albeit, temporarily outside the Commonwealth of Nations (1961–94).

South Africa, officially the Republic of South Africa, is the southernmost country in Africa. It is bounded to the south by 2,798 kilometres (1,739 mi) of coastline that stretches along the South Atlantic and Indian Oceans; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; and to the east and northeast by Mozambique and Eswatini. It also completely enclaves Lesotho. It is the southernmost country on the mainland of the Old World, and the second-most populous country located entirely south of the equator, after Tanzania. South Africa is a biodiversity hotspot, with unique biomes, plant and animal life. With over 62 million people, the country is the world's 23rd-most populous nation and covers an area of 1,221,037 square kilometres. Pretoria is the administrative capital, while Cape Town, as the seat of Parliament, is the legislative capital. Bloemfontein has traditionally been regarded as the judicial capital. The Constitutional Court, the country's highest court, is located in Johannesburg.
