Kemetism (also Kemeticism; both from the Egyptian kmt, usually voweled Kemet, the native name of ancient Egypt), also sometimes referred to as Neterism (from nṯr (Coptic ⲛⲟⲩⲧⲉ noute) "deity"), or Kemetic paganism, is a neopagan religion and revival of the ancient Egyptian religion and related expressions of religion in classical and late antiquity, emerging during the 1970s. A Kemetic or Kemetic pagan is one who follows Kemetism.
There are several main groups, each of which takes a different approach to its beliefs, ranging from eclectic to reconstructionist; however, all of these can be identified as belonging to three strains, including: reconstructed Kemetism (adopting a philological and scholarly approach), a syncretic approach, and a more novel synthesis tending toward monotheism, Kemetic Orthodoxy.
The movement's name is based on an endonym of Egypt, Kemet (the conventional vocalization of hieroglyphic notation km.t). The word is also sometimes written as Takemet, from the fuller tꜣ km.t. In translation from Egyptian it means "black" (or in longer form "black land"), which is derived from the black colour of the fertile mud brought by the Nile during the annual floods (currently no longer occurring due to the existence of the Aswan Dam).
Kemetics refer to the ancient Egyptian deities as the Netjeru, also referred to as the Neteru or the Netjer. Commonly Kemetics prefer to refer to the Netjeru with their ancient Egyptian name, for example they would refer to Horus as Heru, and Anubis as Anpu.
Kemetics do not consider themselves direct descendants of the ancient Egyptian religion but consistently speak of its recreation or restoration. Some Kemetics or hermeticists claim direct continuity with secret societies allegedly continuously existing since the prohibition of Paganism by Roman emperor Theodosius I in 392 CE, or since the closing of the last functional Egyptian temple (of the goddess Isis on the island of Philae) by Emperor Justinian around 535. These claims are historically unprovable and are mythical in nature.
