The Great Synagogue of Rome is the largest synagogue in Rome. The Jewish community of Rome goes back to the 2nd century B.C when the Roman Empire had an alliance of sorts with Judeaunder the leadership of Judah Maccabeus. At that time, many Jews came to Rome from Judea. Their numbers increased during the following centuries due to the settlement that came with Mediterranean trade. Then large numbers of Jews were brought to Rome as slaves following the Jewish–Roman wars in Judea from 63 to 135 CE. The present Synagogue was constructed shortly after the unification of Italy in 1870, when the Kingdom of Italy captured Romeand the Papal States ceased to exist.
