Limpopo (pronounced /lɪmˈpoʊpoʊ/) is the northernmost province of South Africa. The capital is Polokwane, formerly called Pietersburg. The province was formed from the northern region of the Transvaal province in 1994, and initially named Northern Transvaal. The following year, it was renamed Northern Province, which remained the name until 11 June 2003, when the name of the province was formally changed to the name of its most important river, on the border with Zimbabwe and Botswana, after deliberation by the provincial government. Another notable consideration for the name was Mapungubwe, the area where the most ancient gold-using civilisation of the province was discovered a few years earlier.
