the origin of the name "Night of Broken Glass." The main part of the rioting took place on 9–10 November 1938. Jews were beaten to death; 30,000 Jewish men were taken to concentration camps; and 1,668 synagogues ransacked with 267 set on fire. Following Operation Barbarossa launched on 22 June 1941, in the city of Lviv in the occupied territory of the General Government, Ukrainian nationalists organized two large pogroms in July 1941, in which around 6,000 Jews were murdered. In Lithuania, local militant groups engaged in anti-Jewish pogroms on July 25 and 26, 1941 around Kaunas even before the Nazi forces arrived, killing about 3,800 Jews and burning synagogues and Jewish shops. Perhaps the deadliest of these Holocaust-era pogroms was the Iași pogrom in Romania, in which as many as 14,000 Jews were killed by Romanian citizens, police, and military officials. By December 1941, Adolf Hitler decided to completely exterminate European Jews. In January 1942, during the Wannsee conference, several Nazi leaders discussed the details of the "Final Solution of the Jewish question" (Endlösung der Judenfrage). Dr. Josef Bühler urged Reinhard Heydrich to proceed with the "Final Solution" in the General Government. They began to systematically deport Jewish populations from the ghettos and all occupied territories to the seven camps designated as Vernichtungslager, or extermination camps: Auschwitz, Birkenau was the Extermination Camp site Belzec, Chelmno, Majdanek, Sobibór and Treblinka II. Sebastian Haffner published the analysis in 1978 that Hitler from December 1941 accepted the failure of his goal to dominate Europe forever on his declaration of war against the United States, but that his withdrawal and apparent calm thereafter was sustained by the achievement of his second goal—the extermination of the Jews. Even as the German Nazi war machine faltered in the last years of the war, precious military resources such as fuel, transport, munitions, soldiers, and industrial resources were still being heavily diverted away from the war and towards the death camps. By the end of the war, more than half of Jewish population of Europe had been murdered in the Holocaust. Poland, home of the largest Jewish community in Europe before the war, had over 90% of its Jewish population, or about 3,000,000 Jews, murdered by the Nazis. Greece, Yugoslavia, Lithuania, Czechoslovakia, the Netherlands, and Latvia each had over 70% of their Jewish population murdered. Hungary and Albania lost around half of their Jewish populations, the Soviet
