Night of Broken Glass (Kristallnacht) or November pogrome was a pogrom (a series of coordinated attacks) against Jews throughout Nazi Germany and parts of Austria on 9–10 November 1938, carried out by SA paramilitary forces and non-Jewish civilians. German authorities looked on without intervening. The name Kristallnacht comes from the shards of broken glass that littered the streets after Jewish-owned stores, buildings, and synagogues had their windows smashed. German authorities looked on without intervening. At least 91 Jews were killed in the attacks, and 30,000 were arrested and incarcerated in concentration camps. Jewish homes, hospitals, and schools were ransacked, as the attackers demolished buildings with sledgehammers.
