The Boer republics (sometimes also referred to as Boer states) were independent, self-governing republics formed (especially in the last half of the 19th century) by Dutch-speaking inhabitants of the Cape Colony and their descendants. The founders – variously named Trekboers, Boers, and Voortrekkers – settled mainly in the middle, northern, north-eastern and eastern parts of present-day South Africa. Two of the Boer republics achieved international recognition and complete independence: the South African Republic (Dutch: Zuid-Afrikaansche Republiek, ZAR; or Transvaal) and the Orange Free State. The republics did not provide for the separation of church and state, initially allowing only the Dutch Reformed Church, and later also other Protestant churches in the Calvinist (specifically Afrikaner) tradition. The republics came to an end after the Second Boer War of 1899–1902, which resulted in British annexation and later (in 1910) incorporation of their lands into the Union of South Africa.
