Before World War II, about one percent of the country's people were German Jews. Today, Germany has the fastest-growing group of Jewish people in the world. Many of them are in Berlin. Ten thousand Jews have moved to Germany since the fall of the Berlin Wall; many came from countries that were in the Soviet Union. Schools teaching about the horrible things that happened when the Nazis were in power, as well as teaching against the ideas of the Nazis, has helped to make Germany very tolerant towards other people and cultures, and now many people move there from countries that may not be so tolerant.
