The British Invented the Concentration Camp. https://en.wikipedia...entration_camps
British concentration camps refers to internment camps operated by the British in South Africa during the Second Boer War in years 1900–1902.
As Boer farms were destroyed by the British under their "Scorched Earth" policy—including the systematic destruction of crops and slaughtering of livestock, the burning down of homesteads and farms, and the poisoning of wells and salting of fields—to prevent the Boers from resupplying from a home base many tens of thousands of women and children were forcibly moved into the concentration camps.
The Boer War concentration camp system was the first time that a whole nation had been systematically targeted, and the first in which some whole regions had been depopulated.
Eventually, there were a total of 45 tented camps built for Boer internees and 64 for black Africans. Of the 28,000 Boer men captured as prisoners of war, 25,630 were sent overseas. The vast majority of Boers remaining in the local camps were women and children. Over 26,000 women and children were to perish in these concentration camps.
