Today is the anniversary of Kristallnacht, the night in 1938 when German Nazis coordinated a nationwide attack on Jewish homes, businesses, and synagogues. More than 1,000 synagogues were burned or destroyed. Rioters looted about 7,500 Jewish businesses and vandalized Jewish hospitals, homes, schools, and cemeteries. Before that night, the Nazis had killed people secretly and individually. After Kristallnacht, the Nazis felt free to persecute the Jews openly, because they knew no one would stop them.
