Colony of Natal in the context of "Zulu Kingdom"

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 a Christian majority nation with Islam being a minority religion, practised by roughly 2% of the total population. Islam in South Africa has grown in three different phases. The first phase brought the earliest Muslims as part of the involuntary migration of slaves, artisans, political prisoners, and political exiles from the Dutch East Indies to the Cape Colony from 1652 to 1800. The second phase was the arrival of indentured labourers from British India to work in the sugar-cane fields in Natal from 1860 to 1911. Of the approximately 176,000 Indians of all faiths who were transported to the Natal province, almost 7–10% of the first shipment were Muslims.

The third phase has been marked by a wave of African Muslims following the end of apartheid in 1994. Recent figures put the number of these immigrants at approximately between 75,000 and 100,000. In addition, a considerable number of Muslims from South Asia have also arrived as economic migrants. Although the majority of Muslims are Sunni, smaller numbers are Shia, particularly in Cape Town.

South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. Its nine provinces are bounded to the south by 2,798 kilometres (1,739 miles) of coastline that stretches along the South Atlantic and Indian Ocean; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; to the east and northeast by Mozambique and Eswatini; and it encloses Lesotho. Covering an area of 1,221,037 square kilometres (471,445 square miles), the country has a population of over 63 million people (the 6th largest in Africa). Pretoria is the administrative capital, while Cape Town, as the seat of Parliament, is the legislative capital, and Bloemfontein is regarded as the judicial capital. The largest, most populous city is Johannesburg, followed by Cape Town and Durban.

Archaeological findings suggest that various hominid species existed in South Africa about 2.5 million years ago, and modern humans inhabited the region over 100,000 years ago. The first known people were the indigenous Khoisan, and Bantu-speaking peoples who migrated, in waves, from west and central Africa to the region 2,000 to 1,000 years ago. In the north, the Kingdom of Mapungubwe formed in the 13th century. In 1652, the Dutch established the first European settlement at Table Bay, Dutch Cape Colony. Its invasion in 1795 and the Battle of Blaauwberg in 1806 led to British occupation. The Mfecane, a period of significant upheaval, led to the formation of various African kingdoms, including the Zulu Kingdom. The region was further colonised, and the Mineral Revolution saw a shift towards industrialisation and urbanisation. Following the Second Boer War, the Union of South Africa was created in 1910 after the amalgamation of the Cape, Natal, Transvaal, and Orange River colonies, becoming a republic after the 1961 referendum. The multi-racial Cape Qualified Franchise in the Cape was gradually eroded, and the vast majority of Black South Africans were not enfranchised until 1994.

The Indian indenture system was a system of indentured servitude, by which more than 1.6 million workers from British India were transported to labour in European colonies as a substitute for slave labour, following the abolition of the trade in the early 19th century. Although described by colonial authorities as "free" migration, many recruits were deceived, coerced, or kidnapped, leading historians such as Hugh Tinker to characterise the system as a "new form of slavery". The system began with the Atlas voyage to Mauritius in 1834, but early journeys were marked by mortality rates of over 17%, prompting British authorities to impose stricter shipping regulations. The system expanded after the abolition of slavery in the British Empire in 1833, in the French colonies in 1848, and in the Dutch Empire in 1863. British Indian indentureship lasted until the 1920s. This resulted in the development of a large South Asian diaspora in the Caribbean, Natal (South Africa), Réunion, Mauritius, and Fiji, as well as the growth of Indo-South African, Indo-Caribbean, Indo-Mauritian and Indo-Fijian populations. This migration resulted in the formation of large Indian diasporas, including Indo-Caribbean, Indo-Mauritian, Indo-Fijian, and Indo-South African communities. While many descendants celebrate their cultural resilience, historians emphasise the trauma and displacement caused by the indenture system.

Sri Lanka, Malaysia, and Myanmar had a similar system, known as the Kangani system. Indo-Lankan Tamil, Indo-Malaysian, Indo-Burmese and Indo-Singaporean populations are largely descended from these Kangani labourers. Similarly, Indo-East African are descended from labourers who went primarily to work on the Kenya-Uganda Railway, although they were not part of the indentured labourer system.

The South Africa Act 1909 (9 Edw. 7. c. 9) was an act of the Parliament of the United Kingdom that created the Union of South Africa out of the former Cape, Natal, Orange River, and Transvaal colonies, and served as the constitution of the Union from 1910 until 1961. The act also allowed for potential admission of Rhodesia into the Union, a proposal rejected by Rhodesian colonists in a 1922 referendum. The draft proposal was supported by the four colonial parliaments, but was opposed by Cape Colony premier W. P. Schreiner, who raised concerns that it would strip rights from non-white South Africans.

The act was the third major piece of legislation passed by the British Parliament to unite various British colonies and provide some degree of autonomy. This had been done through the British North America Act 1867, which united the Province of Canada (split into Ontario and Quebec) with Nova Scotia and New Brunswick, and the unification of Australia through the Commonwealth of Australia Constitution Act 1900.

During the Second Anglo-Boer War (1899–1902), the British operated concentration camps in the South African Republic, Orange Free State, the Colony of Natal, and the Cape Colony. In February 1900, Lord Kitchener took command of the British forces and implemented controversial tactics that contributed to a British victory.

Using a guerrilla warfare strategy, the Boers lived off the land and used their farms as a source of food, thus making their farms a key item in their many successes at the beginning of the war. When Kitchener realized that a conventional warfare style would not work against the Boers, he began initiating plans to destroy their farms and detain them, which would later cause much controversy among the British public.
