Whichever it is, Europe has remained relatively peaceful since the mid-20th century.
Peter Brecke’s Conflict Catalog documents violent deaths in 3,708 conflicts going all the way back to 1400.
The following infographic estimates the number of violent deaths in wars in Europe between 1800 and 2016.
The first half of the 20th century was of course the bloodiest period in the continent’s history and according to Project InPosterum (rather than Peter Brecke’s global analysis of World War II deaths), 32,156,000 people died in WWII in Europe.
Soon after the conflict ended, the Greek Civil War erupted in 1946, costing another 158,000 lives.
Things started to improve when the European Economic Community was founded in 1957. For example, Europe only experienced 18,409 violent war deaths between 1961 and 1992.
The European Union was established in 1993 and conflicts continued to be rare events. Violent deaths still occurred during the breakup of Yugoslavia, the Russo-Georgian War, the conflict in Donbass and elsewhere.
However, those deaths certainly were not on a scale matching the extensive bloodshed of the 1800s and first half of the 20th century.
