Java War
ND – MPE: 0.1
On his website “Necrometrics” White cites estimates which claim 0.2 million deaths during the Javanese uprising against Dutch colonial rule from 1825 to 1830, mostly from disease. It isn’t clear how many of the deaths were the result of criminal policies by the Dutch.
The Netherlands weren’t an advanced democracy at the time.
Plausible estimates for the number of people killed by nondemocracies range from 0.03 to 0.17 million. I choose 0.1 as the most plausible estimate.
