The name Bolgatanga was derived from the Frafra words "bolga" "rock" and "tẽŋa" "city." Historically Bolgatanga was situated at the southern terminus of the ancient Trans-Saharan trade route. The eastern route converged with the Sahelian route, near Bolgatanga. Along the route, handicrafts—especially straw baskets, hats and fans, as well as leather goods, metal jewellery, and indigenous attires — were exchanged for kola nuts and salt. The Upper East Region, where Bolgatanga lies, is part of what used to be known as the Upper Region. Between 1902 and 1960 the Northern Territory was a British protectorate; it was separated into the Northern and Upper Region on July 1, 1960. The Upper Region was apportioned into Upper East and Upper West Region in 1983.
