Transvaal
The Transvaal (lit. beyond the Vaal [pale river]) was one of the British colonies that united to form the Union of South Africa in 1910. After the Anglo-Boer War of 1899-1902 the bulk of the South African Republic became the Transvaal Colony, while the remainder was incorporated into Natal. It became one of the provinces of South Africa from 1910 until 1994. The province no longer exists, and its territory now forms the provinces of Gauteng, Limpopo and Mpumalanga and part of the North West Province. While no longer existing as an administrative unit, the Transvaal is still a useful geographical term and retains its historical meaning.
