Second Boer War: The Battle of Spion Kop between the forces of the South African Republic and the Orange Free State and British forces ends in a British defeat.

The Second Boer War, also known as the Boer War, Transvaal War, Anglo–Boer War, or South African War, was a conflict fought between the British Empire and the two Boer republics over Britain's influence in Southern Africa.

The Battle of Spion Kop was a military engagement between British forces and two Boer Republics, the South African Republic and the Orange Free State, during the campaign by the British to relieve the besieged city Ladysmith during the initial months of the Second Boer War. The battle was fought 23–24 January 1900 on the hilltop of Spioen Kop^(a), about 38 km (24 mi) west-southwest of Ladysmith and resulted in a Boer victory.

The South African Republic, also known as the Transvaal Republic, was an independent Boer republic in Southern Africa which existed from 1852 to 1902, when it was annexed into the British Empire as a result of the Second Boer War.

The Orange Free State was an independent Boer-ruled sovereign republic under British suzerainty in Southern Africa during the second half of the 19th century, which ceased to exist after it was defeated and surrendered to the British Empire at the end of the Second Boer War in 1902. It is one of the three historical precursors to the present-day Free State province.
