The Treaty of Vereeniging was a peace treaty, signed on 31 May 1902, that ended the Second Boer War between the South African Republic and the Orange Free State on the one side, and the United Kingdom on the other. This settlement provided for the end of hostilities and eventual self-government to the Transvaal (South African Republic) and the Orange Free State as British colonies. The Boer republics agreed to come under the sovereignty of the British Crown and the British government agreed on various details.
