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 ( 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 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. The Dutch East India Company (VOC) first issued land to the Free Burghers in 1657. The Free Burghers established two colonies at the Liesbeeck River near Rondebosch in the Western Cape. Following an application process, the Free Burghers formed two groups, the first group named their settlement Harman's Colony and the second group named theirs Stephen's Colony. By 1670, the VOC decided to grant additional land to the Free Burghers in order to increase grain production for the purpose of sustainability since grain had to be imported. The Free Burgher settlements gradually expanded towards the interior of South Africa. The United Kingdom took over from the Netherlands as the colonial power at the Cape of Good Hope in 1806. Subsequently, a number of its Dutch-speaking inhabitants trekked inland, first in smaller numbers, then in groups as large as almost a hundred people, after 1834 even in groups of hundreds. There were many reasons why the Boers left the Cape Colony; among the initial reasons were the language laws.
