Louis Botha (27 September 1862 – 27 August 1919) was an Afrikaner and first Prime Minister of the Union of South Africa—the forerunner of the modern South African state. A Boer war hero during the Second Boer War, he would eventually fight to have South Africa become a British Dominion.
Botha was a representative of his countrymen in the peace negotiations of 1902, and was signatory to the Treaty of Vereeniging. After the grant of self-government to the Transvaal in 1907, General Botha was called upon by Lord Selborne to form a government.
In the period of reconstruction under British rule, Botha went to Europe with de Wet and de la Rey to raise funds to enable the Boers to resume their former avocations. Botha, who was still looked upon as the leader of the Boer people, took a prominent part in politics, advocating always measures which he considered as tending to the maintenance of peace and good order and the re-establishment of prosperity in the Transvaal.
In 1911, together with another Boer war hero, Jan Smuts, he formed the South African Party, or SAP. Widely viewed as too conciliatory with Britain, Botha faced revolts from within his own party and opposition from James Barry Munnik Hertzog's National Party. When South Africa obtained dominion status in 1910, Botha became the first Prime Minister of the Union of South Africa.
General Louis Botha died of heart failure following an attack of Spanish influenza on 27 August 1919. Botha was laid to rest in Heroes Acre Pretoria.
