Justin II

Justin II, d. 578, Byzantine emperor (565–78), nephew and successor to Justinian I. He allied himself with the Turks and resumed the wars with Persia. During his reign Slavs and Avars attacked the empire, and Italy was invaded by the Lombards under Alboin. He severely persecuted the Monophysites. Subject to fits of insanity, he adopted (574) the general Tiberius as his son. Tiberius was made caesar and exercised power until he succeeded Justin (578) on the latter's death.
