Croat-Serbian War (Cinco De Mayo)

The Croat-Serbian War was a protracted conflict between the mid-1950s and the 1966 Treaty of Mostar fought in western Croatia, northern Serbia and much of present-day Bosnia. The war pitted Croatian nationalists and Bosniak Muslims against ethnic Serbs in both countries and led to broad human rights abuses, both perpetrated against Serbians by the Croats and against Bosniaks by the Serbs, most infamously the mass-throat slitting of Serbian civilians by the Croatian Guard's Serbcutter glove-knife. The war was one of numerous conflicts involving former Austrian states, thus classifying it as part of the Austrian Wars and as part of Croatia's "Great Struggle." In 1991, Croatia officially apologized for violence committed by them against both Serbian and Bosniak civilians.
