After Germany declared war on the United States, Croatia followed suit. Heavily influenced by German Nazism, the Croatian movement Ustaše’s goal of persecuting Serbians and converting them to Roman Catholicism begat a mass genocide of the Serbs, Jews and Romanians. Anywhere from 300,000 to 500,000 people were killed. At least 100,000 were killed in concentration camps.

This country can only be a Croatian country, and there is no method we would hesitate to use in order to make it truly Croatian and cleanse it of Serbs, who have for centuries endangered us and who will endanger us again if they are given the opportunity.
— Milovan Žanić, the minister of the NDH Legislative council, May 2, 1941
