Haredi Judaism (Hebrew: חֲרֵדִי Ḥaredi, IPA: [χaʁeˈdi]; also spelled Charedi, plural Charedim) is a broad spectrum of groups within Orthodox Judaism, all characterized by rejection of modern secular culture. Its members are often referred to as strictly Orthodox or ultra-Orthodox in English. The term "ultra-Orthodox", however, is considered a derogatory slur by some in the community. Haredim regard themselves as the most religiously authentic group of Jews, although this claim is contested by other streams.
