We just got back from a trip to Lithuania! I'll post more photos, but here is information about the Holocaust in that country.
Over 95% of Lithuanian Jews were murdered: perhaps 195,000 Jews in a population of about 200,000-210,000. Vilnius was once called the Jerusalem of the North. Much of this genocide happened in 1941, with gentile collaboration inflamed by both Nazi propaganda and by resentment and scapegoating about the recent Soviet occupation. I wanted to visit the single remaining synagogue in Vilnius (before the war, there were around 100 synagogues) but I missed their limited hours of being open for visitors. However, we visited the streets of the former ghetto. We happened to find the Genocide and Resistance Research Centre of Lithuania. I purchased two books there. They asked where I was from and I said from Ohio in the states. They gave me a third book as a gift.
