The South African War (formally known as the Anglo-Boer War) broke out in 1899 as a result of the British invasion of the Transvaa lafter gold had been discovered in the region in 1886.
Around 26 000 Boer women and children, as well as 15 000 black people, died in concentration camps during the course of the South African War.
Boer women and children, as well as their black servants, were taken to concentration camps, where they were met with appalling conditions, malnutrition, diseases and in many instances, death.
The war also resulted in the destruction of over 30 000 Boer farm houses.
The Treaty of Vereeniging was signed in May 1902 and it brought the closure of the concentration camps and an end to the inhumane treatment of Boer women and children at the hands of the British.
