A rebellion in the Cyclades against Emperor Leo III the Isaurian may stem from opposition to his doctrines.

Agallianos Kontoskeles is serving as tourmarches of the Theme of Hellas in 726/7 when the theme erupts in revolt against the emperor.

Agallianos, along with Stephen, possibly the commander of the naval district of the Cyclades, becomes the leader of the revolt, and a certain Kosmas is acclaimed as emperor by the rebels.

However, the rebel fleet is defeated on April 18, 727 by the loyalist navy through the use of Greek fire.

Agallianos drowns when he falls from the board of his ship into the sea in full armor, while Stephen and Kosmas are captured and beheaded. (On account of his surname "Kontoskeles" ("short-leg"), the Patria of Constantinople erroneously involves him in the construction of the Kontoskalion harbour in Constantinople.

Venetian authority becomes concentrated in the city-state’s first doge, whose title derives from the Latin “dux” ("leader").

Orso Ipato, the third traditional Doge of Venice, is the first historically known.

Elected leader of Venice around 726, will eventually be appointed Roman consul by Emperor Leo III.

According to John Julius Norwich (A History of Venice. Alfred A. Knopf: New York, 1982), Paolo Lucio Anafesto, the reputed first doge of Venice, was actually Exarch Paul.

Moreover, Paul's magister militum had the same first name as Paoluccio's reputed successor, Marcellus Tegallianus, casting doubt on the authenticity of that doge as well.
