 Many scholars today mention evidence for a "Dynasty 0" that preceded the First Dynasty I.The term "Dynasty 00" is also used for the period preceding Dynasty 0 in connection with the Abydos-Thinis area and may correspond to a theoretical "Thinite Confederacy".The terms "Dynasty 0" and especially "Dynasty 00" are widely seen as playful, but are frequently used nonetheless in absence of a more agreed-upon term.
