Political map of Sub-Saharan Africa 31 May 1902 (Treaty of Vereeniging): The Second Boer War resulted in an uneasy victory for the British. Not only had Britain’s ruthless suppression of the Boers (British concentration camps) led to international condemnation (Boer foreign volunteers) but the financial costs of the war had been immense. In the resulting peace treaty (Treaty of Vereeniging), the Boer republics agreed to become British colonies; in return, they were promised self-government and the issue of black enfranchisement (Apartheid) was sidelined.
