In 1904 the Herero people of South West Africa made their final stand against German Colonial troops with their backs against the slopes of Waterberg mountain in today’s Namibia. The battle marked the beginning of what has been called the first genocide of the 20th Century as tens of thousands were killed, driven into the desert to die and thousands more held in concentration camps. The Nama, another indigenous group suffered the same fate soon after. And their deaths fed a bizarre and gruesome trade in body parts, driven by racial anthropologists in Germany intent on proving the superiority of their own race.
