Nazis launch Kristallnacht
On November 9, 1938, in an event that would foreshadow the Holocaust, German Nazis launch a campaign of terror against Jewish people and their homes and businesses in Germany and Austria. The violence, which continued through November 10 and was later dubbed “Kristallnacht,” or “Night of Broken Glass,” after the countless smashed windows of Jewish-owned establishments, left approximately 100 Jews dead, 7,500 Jewish businesses damaged and hundreds of synagogues, homes, schools and graveyards vandalized. An estimated 30,000 Jewish men were arrested, many of whom were then sent to concentration camps for several months; they were released when they promised to leave Germany. Kristallnacht represented a dramatic escalation of the campaign started by Adolf Hitler in 1933 when he became chancellor to purge Germany of its Jewish population.
Explanation:
When the treaty of Versailles was negotiated (without the Germans mind you) they didn’t refuse to allow German delegation. They didn’t invite the Germans because they were under the impression that the Germans had surrendered (instead of the cease war that meant neither side won.) Since Germany had “lost,” the loser had no say in the terms of the treaty and was forced to accept it.
The treaty of Versailles was one of the causes of World War II.
