Historical Context
Jasenovac was the largest concentration camp run by the Ustaše of the Independent State of Croatia, a client state of Nazi Germany and Fascist Italy. Estimates of the total number killed there range widely, commonly cited between roughly 83,000 and 100,000, with Serbs constituting the largest category of victims.
The persecution of Orthodox Serbs had an explicitly religious dimension. Serbs were often deported after refusing forced conversion to Roman Catholicism, and the Serbian Orthodox Church remembers many of those killed as having died for their faithfulness to Orthodoxy. This understanding underlies their commemoration as New Martyrs.
