Kristallnacht, or the Night of Broken Glass.
Jewish homes were ransacked, as were shops, towns and villages, as stormtroopers and civilians destroyed buildings with sledgehammers, leaving the streets covered in pieces of smashed windows—the origin of the name "Night of Broken Glass." Ninety-one Jews were killed, and 30,000 Jewish men. A quarter of all Jewish men in Germany were taken to concentration camps, where they were tortured for months, with over 1,000 of them dying.
This was a pogrom or series of attacks against Jews throughout Nazi Germany and parts of Austria on November 9–10, 1938.
