Kristallnacht or the Night of Broken Glass, also called the November Pogrom(s), was a pogrom against Jews carried out by SA paramilitary forces and civilians throughout Nazi Germany on 9–10 November 1938. The German authorities looked on without intervening. The name Kristallnacht comes from the shards of broken glass that littered the streets after the windows of Jewish-owned stores, buildings and synagogues were smashed. The pretext for the attacks was the assassination of the German diplomat Ernst vom Rath by Herschel Grynszpan, a 17-year-old German-born Polish Jew living in Paris.
