"Theodosius III or Theodosios III (Greek: Θεοδόσιος Γ΄) was Byzantine emperor from c. May 715 to 25 March 717. Before rising to power and seizing the ...
throne of the Byzantine Empire, he was a tax collector in Adramyttium. In 715, the Byzantine Navy and the troops of the Opsician Theme revolted against Byzantine Emperor Anastasios II (r. 713–715), acclaiming the reluctant Theodosius as Emperor Theodosius III. Theodosius led his troops to Chrysopolis and then Constantinople, seizing the city in November 715, although Anastasios would not surrender until several months later, accepting exile into the monastery in return for safety. Many themes refused to recognize the legitimacy of Theodosius, believing him to be a puppet of the Opsicians, especially the Anatolics and the Armeniacs under their respective strategoi (generals) Leo the Isaurian and Artabasdos.
