The Brussels massacre was an anti-Semitic episode in Brussels (then within the Duchy of Brabant) in 1370 in connection with an alleged host desecration at the Brussels synagogue. A number of Jews, variously given as six or about twenty, were executed or otherwise killed, while the rest of the small community was banished. The event occurred on May 22.The supposedly recovered hosts became objects of veneration for local Christians as the Sacrament of Miracle. The cult survived until after the Second World War and the Holocaust, after which its antisemitic elements pushed the local church to derecognise it. It was claimed that the hosts had been stabbed by Jews and had miraculously shed blood, but been otherwise unharmed. The reliquary (without the hosts) is currently preserved in the cathedral's treasury (the hosts may have been present inside it as late as the year 2000).
