An anthropologist who written quite a bit on the high levels of death by violence in the past is Lawrence Keeley (who is cited in the paper I liked to). His work isn’t available free online to link to, but here are some summaries of his work:
A quick note, the 17th century is not what occurs to me as ancient times and every thing xited here simply talks about violence occurring - nothing at all showing comparable modern times.
60% of the male population of Serbia died in WWI.
I have not said that "ancient times’ were not violent - I’m looking for something that says they were “a lot more violent” than modern times. What I questioned in fact was the premise put forth that it is common knowledge that we all accept that ancient times were a lot more violent.
As I understand it, one of the points anthropologists are emphasizing is that, although bloody, modern wars end sooner or later. The overall death rate across time is therefore lower – much lower – than it used to be, when lethal violence was the normal order of the day, century after century.
