Surdulica massacre
The Surdulica massacre was the mass murder of Serbian men by Bulgarian occupational authorities in the southern Serbian town of Surdulica in 1916 and early 1917, during World War I. Members of the Serbian intelligentsia in the region, mostly functionaries, teachers, priests and former soldiers, were detained by Bulgarian forces--ostensibly so that they could be deported to the Bulgarian capital, Sofia--before being taken into the forests around Surdulica and killed.
