On the night of November 9, 1938, violence out against Jews broke out across the city of Reich. It appeared to be unplanned, set off by Germans' anger over the assassination of a German official in Paris at the hands of a 17 year old Jewish teenager. At least 91 Jews were killed in “The Night of the Broken Glass” and 30,000 were arrested in concentration camps. Jewish hospitals, schools, and homes were attacked. They demolished the buildings with sledgehammers. Over 1,000 synagogues were burned, and over 7,000 Jewish businesses destroyed or damaged.
