Mbala is Zambia's most northerly large town and seat of Mbala District in Northern Province, occupying a strategic location close to the border with Tanzania and controlling the southern approaches to Lake Tanganyika, 40 km by road to the north-west, where the port of Mpulungu is located. It had a population of about 20,000 in 2006. Under the name Abercorn, Mbala was a key outpost in British colonial control of this part of south-central Africa.

The British South Africa Company was chartered in 1889 following the amalgamation of Cecil Rhodes' Central Search Association and the London-based Exploring Company Ltd, which had originally competed to capitalize on the expected mineral wealth of Mashonaland but united because of common economic interests and to secure British government backing. The company received a Royal Charter modelled on that of the British East India Company. Its first directors included The 2nd Duke of Abercorn, Rhodes himself, and the South African financier Alfred Beit. Rhodes hoped BSAC would promote colonisation and economic exploitation across much of south-central Africa, as part of the "Scramble for Africa". However, his main focus was south of the Zambezi, in Mashonaland and the coastal areas to its east, from which he believed the Portuguese could be removed by payment or force, and in the Transvaal, which he hoped would return to British control.
