Kristallnacht refers to the wave of violent anti-Jewish pogroms which took place on November 9 and 10, 1938, throughout Germany, annexed Austria, and in areas of the Sudetenland in Czechoslovakia recently occupied by German troops. Instigated primarily by Nazi Party officials and members of the SA (Sturmabteilungen: literally Assault Detachments, but commonly known as Storm Troopers) and Hitler Youth, Kristallnacht owes its name to the shards of shattered glass that lined German streets in the wake of the pogrom—broken glass from the windows of synagogues, homes, and Jewish-owned businesses plundered and destroyed during the violence.
