Orange Free State in the context of "British Resident"

The Union of South Africa (Dutch: Unie van Zuid-Afrika; Afrikaans: Unie van Suid-Afrika, pronunciation) was a British Dominion and, later, a Commonwealth realm in southern Africa from 1910 to 1961. It was the historical predecessor to the present-day Republic of South Africa. It came into existence on 31 May 1910 with the unification of the Cape, Natal, Transvaal, and Orange River colonies. It included the territories that were formerly part of the South African Republic and the Orange Free State.

Following World War I, the Union of South Africa was a signatory of the Treaty of Versailles and became one of the founding members of the League of Nations. It was mandated by the League with the administration of South West Africa (now known as Namibia). South West Africa became treated in most respects as another province of the Union, but it never was formally annexed.

South Africa is divided into nine provinces. On the eve of the 1994 general election, South Africa's former homelands, known as Bantustans, were reintegrated into the country, and the four provinces were increased to nine. The borders of Natal and the Orange Free State were retained, while the Cape Province and Transvaal were divided into three provinces each, plus North West Province which straddles the border of and contains territory from both these two former provinces. The twelfth, thirteenth and sixteenth amendments to the Constitution of South Africa changed the borders of seven of the provinces.

The Free State is a province of South Africa. Its capital is Bloemfontein, which is also South Africa's judicial capital. Its historical origins lie in the Boer republic called the Orange Free State and later the Orange Free State Province.

Free state is a term occasionally used in the official titles of some states throughout the world with varying meanings depending on the context. In principle, the title asserts and emphasises a particular freedom of the state in question, but this is not always reflected in practice. Some states use the title to assert sovereignty or independence from foreign domination, while others have used it to assert autonomy within a larger nation-state. Sometimes "free state" is used as a synonym for "republic".

The republican sense of the term derives from libera res publica (literally, "the free public thing/affair"), a term used by Latin historians for the period of the Roman Republic, though not all "free states" have been republics. The historical German free states and the Orange Free State of Southern Africa were republican in form, while the Congo Free State and Irish Free State were governed under forms of monarchy.

The Second Boer War (Afrikaans: Tweede Vryheidsoorlog, lit. 'Second Freedom War', 11 October 1899 – 31 May 1902), also known as the Boer War, Transvaal War, Anglo–Boer War, or South African War, was a conflict fought between the British Empire and the Boer republics (the South African Republic and Orange Free State) over Britain's influence in Southern Africa.

The Witwatersrand Gold Rush caused an influx of "foreigners" (Uitlanders) to the South African Republic (SAR), mostly British from the Cape Colony. As they were permitted to vote only after 14 years residence, they protested to the British authorities in the Cape. Negotiations failed at the botched Bloemfontein Conference in June 1899. The conflict broke out in October after the British government decided to send 10,000 troops.

The quagga (/ˈkwɑːxɑː/ or /ˈkwæɡə/) (Equus quagga quagga) is an extinct subspecies of the plains zebra that was endemic to South Africa until it was hunted to extinction in the late 19th century. It was long thought to be a distinct species, but mtDNA studies have supported it being a subspecies of plains zebra. A more recent study suggested that it was the southernmost cline or ecotype of the species.

The quagga is believed to have been around 257 cm (8 ft 5 in) long and 125–135 cm (4 ft 1 in – 4 ft 5 in) tall at the shoulders. It was distinguished from other zebras by its limited pattern of primarily brown and white stripes, mainly on the front part of the body. The rear was brown and without stripes, and appeared more horse-like. The distribution of stripes varied considerably between individuals. Little is known about the quagga's behaviour, but it may have gathered into herds of 30–50. Quaggas were said to be wild and lively, yet were also considered more docile than the related Burchell's zebra. They were once found in great numbers in the Karoo of Cape Province and the southern part of the Orange Free State in South Africa.

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 the Orange Free State Province.
