Martyrius was deposed by prominent Non-Chalcedonian Peter the Fuller in 470, the latter supported by Zeno, a general and son-in-law of Byzantine Emperor Leo I. Martyrius fled to Constantinople, where he was supported by Patriarch Gennadius, whose influence with Leo secured Martyrius's brief restoration. However, Peter the Fuller soon forced out Martyrius again, himself occupying the patriarchate once more. Martyrius again appealed to Leo, who again deposed Peter the Fuller, this time in favor of a new Chalcedonian successor, Julian.
