The Twenty Years' Anarchy is a historiographic term used by some modern scholars^[1][2][3] for the period of acute internal instability in the Byzantine Empire marked by the rapid succession of several emperors to the throne between the first deposition of Justinian II in 695 and the ascent of Leo III the Isaurian to the throne in 717, marking the beginning of the Isaurian dynasty.
