"no less than fifty-nine million human animals were killed in inter-group clashes "
The overwhelming number of killings can be accounted for by war
- around 18 and a half million in WW1, around 70 to 85 million in WW2 - the massacre of the Congolese by the Belgians at the beginning of the 20th century alone accounts for up to 10 million..... and so ad infinitum.
I'm not sure where Morris got his figures, but they appear to be somewhat conservative.
All these killings were brought about by politicians or national leaders in support of acquisition or political or economic superiority - not a referendum in sight.
