The 1946 Kielce Pogrom

This article records tradition as it has been passed down and reported. Its sources are not yet part of the atlas's verified catalogue.

A one-day outbreak of mob violence struck Kielce, Poland, on 4 July 1946, when a crowd of civilians, soldiers and police attacked a building at 7 Planty Street housing around 150 to 160 Jewish Holocaust survivors, after a Polish boy's disappearance was rumored to be a Jewish ritual blood libel kidnapping. The killing was set off by that rumor, the centuries-old antisemitic accusation that Jews murder Christian children for ritual purposes, revived when the boy went missing and was said on his return to have been held by Jews in the building. The building's residents were beaten, shot and thrown from windows over several hours before the violence spread into the streets, with further attacks on Jews found on passing trains.

It was the deadliest single attack on Jewish survivors anywhere in postwar Europe. A hasty military trial opened five days later; nine of twelve defendants were sentenced to death and executed on 12 July 1946, eight days after the pogrom, and the remaining three received long prison terms. News of the killings accelerated the flight of Poland's surviving Jewish population, tens of thousands of whom left the country within months, in a decision the pogrom itself did more than any other single event to provoke.

Local Catholic clergy and officials present in Kielce on 4 July 1946 did not intervene to disperse the crowd that attacked the Jewish committee building at 7 Planty Street, and Gross situates the blood libel rumor's traction that day within a wider current of Polish Catholic antisemitism in the period rather than treating it as an isolated superstition. The mob itself was a civilian crowd joined over the course of the day by uniformed soldiers, militia and state police, rather than violence ordered by the Polish state, though state forces present did little to stop it and some joined in.

Poland's Institute of National Remembrance closed its own 2006 investigation without finding evidence for theories that Soviet or Polish communist security services deliberately provoked the violence, concluding the likelier cause was a coincidence of the blood libel rumor, wartime trauma and a state and church slow to respond. Some historians, Gross among them, dispute that conclusion as too exculpatory of the state's own responsibility for allowing the violence to run unchecked for hours once it began. Poland's own postwar state answered with an unusually swift domestic prosecution, trying and executing nine men within eight days, rather than a genocide or crimes against humanity finding by any international body, since no such body existed with jurisdiction over an internal Polish pogrom in 1946.
