Answer:
Kristallnacht refers to the November 1938 event in Nazi Germany as part of Holocaust, a systematic persecution of Jews.
In October 1938, 15,000 Jews of Polish descent were expelled from Germany and landed on the Polish border. The anti-Semitic Polish government, which spoke on its own "Jewish issue", refused to receive them.
In retaliation, seventeen-year-old Herschel Grunspan, who was expelled from his parents, assassinated a German consul in Paris on November 7, killing him with a gun. The Nazi Party declared it part of a worldwide Jewish conspiracy, and on the night of November 9-10, "spontaneous" anti-Jewish riots were organized. At least 7,000 shops were destroyed and looted, Jewish cemeteries were desecrated, 177 synagogues were burnt and 91 Jews were killed. About 30,000 Jews were arrested and taken to concentration camps. By the end of the year, most had been released, but in the meantime, thousands had lost their lives.
In addition, the Nazi state imposed a fine of one billion marks on German Jews as a punishment for the assassination. At the same time, an order was issued to surrender all Jewish shops and businesses, which were still in existence, into "Aryan" hands. The remaining Jews thus remained without much of their capital and were virtually excluded from German economic life. The final solution in the Holocaust followed.
