 The Palaiologoi ruled Byzantium at its weakest point in history, and the empire underwent significant economical and political decline.Even in this state, the empire, famous for its frequent civil wars, was unable to stay united.In 1320, Emperor Andronikos II Palaiologos attempted to disinherit his grandson Andronikos III Palaiologos, despite the death of Andronikos II's son, heir and co-emperor Michael IX Palaiologos (Andronikos III's father).
