The Bantu people to the east of the Great Karoo did not occupy this arid region due to the scarce rainfall which prevented the farming of cattle. In 1854, Daniel Halladay invented the multibladed windpump (windmill) in the USA. It was perfected in 1883, and soon South Africa (and elsewhere) produced them in large numbers. These windpumps transformed the Great Karoo, making permanent settlement and stock farming (predominantly sheep) possible over large parts of the Karoo for the first time.
