Kristallnacht (German pronunciation: [kʁɪsˈtalnaχt] lit. 'crystal night') or the Night of Broken Glass, also called the November pogrom(s) (German: Novemberpogrome, pronounced [noˈvɛm.bɐ.poˌɡʁoːmə] ), was a pogrom against Jews carried out by the Nazi Party's Sturmabteilung (SA) and Schutzstaffel (SS) paramilitary forces along with some participation from the Hitler Youth and German civilians throughout Nazi Germany on 9–10 November 1938. The German authorities looked on without intervening. The euphemistic 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.

A pogrom is a violent riot incited with the aim of massacring or expelling an ethnic or religious group, particularly Jews. The term entered the English language from Russian to describe 19th- and 20th-century attacks on Jews in the Russian Empire. Similar attacks against Jews which also occurred at other times and places became known retrospectively as pogroms. Sometimes the word is used to describe publicly sanctioned purgative attacks against non-Jewish groups. The characteristics of a pogrom vary widely, depending on the specific incident, at times leading to, or culminating in, massacres.
