Religious Zionism is an ideology that views Zionism as a fundamental component of Orthodox Judaism. Its adherents are also referred to as Dati Leumi, and in Israel, they are most commonly known by the plural form of the first part of that term: Datiim. The community is sometimes called 'Knitted kippah', the typical head covering worn by male adherents to Religious Zionism.

Haredi Judaism consists of groups within Orthodox Judaism that are characterized by their strict interpretation of religious sources and their accepted halakha and traditions, in opposition to more accommodating or modern values and practices. Its members are usually referred to as ultra-Orthodox in English; however, the term "ultra-Orthodox" is considered pejorative by many of its adherents, who prefer terms like strictly Orthodox or Haredi. Haredi Jews regard themselves as the most religiously authentic group of Jews, although other movements of Judaism disagree.
