1J - The expansion of the British Empire in Africa
Between c1857 and c1890, Britain extended its African possessions and tightened its control of important routes and markets. Learn why expansion took different forms in different regions, and why the Suez Canal helped turn financial involvement in Egypt into military occupation.
African expansion and its motives
Britain already possessed African coastal settlements and the Cape Colony in 1857, but it did not control the continent's interior. African kingdoms, trading networks and communities exercised their own authority. European maps could conceal this political reality by marking an area as unexplored or by colouring a claimed territory before its inhabitants had been conquered.
Imperial expansion meant extending British power, but annexation was only one method. A colony came under British sovereignty; a protectorate usually retained some local institutions while Britain claimed authority over external affairs and increasingly intervened internally. Trading companies and treaties could establish influence before a substantial colonial administration existed.
Annexation
A state's formal incorporation of a territory into its possessions. A declared annexation does not by itself prove effective control over everyone living there.
Several motives interacted. Merchants wanted secure access to commodities and markets. Ministers sought naval bases and safe communications with India. Missionaries promoted conversion and opposed the slave trade, while advocates of empire presented British intervention as a civilising duty. Such claims commonly assumed European superiority and ignored African political rights. From the 1880s, French and German acquisitions made ministers fear that delay would leave Britain excluded from valuable territory.
The importance of each motive depended on the case. Britain could trade without conquest, while a strategically important possession could be expensive and commercially disappointing. Expansion therefore needs an explanation of the decision to impose political control, not merely proof that a region contained a useful resource.
Southern Africa and mineral wealth
Southern Africa combined a strategic sea route with settler societies, independent African states and Boer republics. The Cape offered a base on the route around Africa to Asia. Britain annexed Natal in 1843; the Orange Free State and Transvaal were independent republics established by Dutch-speaking settlers known as Boers. This background explains why later expansion involved conflicts among several organised societies rather than movement into empty land.
Diamond discoveries from 1867 increased the value of territory around Kimberley. Britain annexed Griqualand West in 1871, bringing the diamond fields under British authority. Mining drew in capital, migrant labour and transport investment. It also intensified competition over land and control of workers. Gold discoveries on the Witwatersrand in 1886 subsequently increased the economic importance of the Transvaal, which remained outside direct British rule at this point.
Colonial Secretary Lord Carnarvon wanted a confederation joining southern African territories under British leadership. Local opposition obstructed that design. Britain annexed the Transvaal in 1877, but Boer resistance and the First Anglo-Boer War of 1880–81 forced the restoration of its internal self-government. British attempts to remove the independent Zulu kingdom as an obstacle led to war in 1879. The Zulu victory at Isandlwana showed the danger of assuming effortless conquest; their eventual defeat at Ulundi did not remove the costs and instability of intervention.
Britain established the Bechuanaland Protectorate in 1885 north of the separately administered British Bechuanaland colony. Control protected routes towards the interior and checked competing settler and European claims. These developments reveal both expansion and limits: British power grew, but African and Boer resistance altered its form and timing.
West and East African footholds
West African expansion often began with ports and commerce before extending inland. Lagos was annexed in 1861. In the Gold Coast, conflict with the Asante kingdom culminated in the British expedition of 1873–74; the coastal Gold Coast colony was established in 1874. The expedition did not annex the entire Asante kingdom. Distinguishing a coastal possession from later inland conquest prevents an exaggerated picture of British control in the 1870s.
Along the Niger, palm oil and other trade encouraged British commercial involvement. The Royal Niger Company received its charter in 1886 and used agreements with African rulers, trading posts and armed power to advance British claims. The Oil Rivers Protectorate, declared in 1885 in the Niger delta, was a separate arrangement. Neither was yet the later unified colony of Nigeria.
