With around half a million Jews, France is home to the third biggest community in the world, exceeded only by Israel and the United States. There has been a Jewish presence in France since the early Middle Ages. During the medieval period France was widely known for the quality of its Torah scholars, especially Rabbi Shlomo Yitzchaki. Known popularly as Rashi, Rabbi Yitzchaki wrote extensive commentaries on the Bible and Talmud, both of which have been studied by scholars and laymen alike for the better part of a millennium. Following the French Revolution, France became the first European nation to emancipate its Jews, although anti-Semitism persisted for centuries. In 1936, Léon Blum became France first Jewish Prime Minister. The French affiliate of the World Jewish Congress is the Conseil Représentatif des Institutions Juives de France (CRIF – Representative Council of Jews of France).
