The Anglo-Zulu War was fought in 1879 between the British Empire and the Zulu Kingdom.
In 1874, Sir Henry Bartle Frere was sent to South Africa as High Commissioner for the British Empire to bring the plans into being. Among the obstacles were the presence of the independent states of the South African Republic and the Kingdom of Zululand and its army.
Frere, on his own initiative, without the approval of the British government and with the intent of instigating a war with the Zulu, had presented an ultimatum on 11 December 1878, to the Zulu king Cetshwayo with which the Zulu king could not comply.
Cetshwayo did not comply and Bartle Frere sent Lord Chelmsford to invade Zululand. The war is notable for several particularly bloody battles, including a stunning opening victory by the Zulu at Isandlwana, as well as for being a landmark in the timeline of imperialism in the region.
The war eventually resulted in a British victory and the end of the Zulu nation's independence.
