Partition of British India
ND – MPE: 0.5
White cites 14 estimates for the number of innocent people killed in the partition violence of 1947, which range from 0.2 to 0.6 million. Most sources claim 0.5 million. I choose 0.5 million as the most plausible estimate.
Many historians argue that the British bear a large share of the blame for the violence, because of their divide-and-conquer policies.
