Jewish religious movements, sometimes called "denominations", include different groups which have developed among Jews from ancient times. Today, the main division is between the "traditional Judaism" (Orthodox and Conservative), and Reform, with several smaller movements alongside them. This denominational structure is mainly present in the United States, while in Israel, the fault lines are between Haredi Judaism (Haredim), Religious Zionism (Datim), Masortim (traditional) and Hiloni (secular) Jews.
