Leon II, in 732, submitted the authority of the Patriarch of Constantinople to almost the entire Balkan peninsula, except Thrace. This, together with the weakness of the Byzantine military positions in Italy, caused the papacy to request the help of the Franks. This resulted in the alliance between Stephen I and Pepin, which meant that the papacy was moving away from the Byzantine Empire.
