Boer is the Dutch word for farmer, which came to denote the descendants of the Dutch-speaking settlers of the eastern Cape frontier in Southern Africa during the 18th century, as well as those who left the Cape Colony during the 19th century to settle in the Orange Free State, Transvaal (which are together known as the Boer Republics), and to a lesser extent Natal. Their primary motivations for leaving the Cape were to escape British rule and extract themselves from the constant border wars between the British imperial government and the native tribes on the eastern frontier.
