Also known as Haredi (Hebrew for “Orthodox”) Judaism. It is the most conservative sect of Orthodox Judaism and requires a strict adherence to the religious practices and moral precepts outlined in the Torah and Talmud; this strict adherence can also include separation from others that don’t follow the same practices. In Israel, with the exception of the Shas party, many ultra-Orthodox Jews don’t directly participate in political parties. See “ultra-Orthodox Judaism."
