The Kraljevo massacre was the World War II mass murder of approximately 2,000 residents of the city of Kraljevo in the German-occupied territory of Serbia between 15 and 20 October 1941 by the German Army. The massacre came in reprisal for a joint Partisan–Chetnik attack on a German garrison during the Siege of Kraljevo in which 10 German soldiers were killed and 14 wounded. The number of hostages to be shot was calculated based on a ratio of 100 hostages executed for every German soldier killed and 50 hostages executed for every German soldier wounded, a formula devised by Adolf Hitler with the intent of suppressing anti-Nazi resistance in Eastern Europe. The German Army initially responded by rounding up and executing 300 Serbian civilians, described in contemporary documents as "communists, nationalists, democrats and Jews." Over the following several days, all men between the ages of 14 and 60 were arrested and herded into a makeshift detention centre at the local rolling-stock factory. Once there, their papers were checked and their names entered into a ledger.
