The most stirring episode in the history of the Peiraeus is the seizure of Munychia by Thrasybulus and the exiles from Phyle, and the consequent destruction of the "30 tyrants" in 404 B.C. The three chief arsenals of the Peiraeus were named Munychia, Zea and Cantharus, and they contained galley slips for 82, 196 and 94 slips respectively in the 4th century B.C.
After some family disputes the power passed to his brother Thrasybulus, who was driven out next year by a general rising.
In this revolution Thrasybulus and his mercenaries held the fortified quarters of Ortygia and Achradina; the revolted people held the unwalled suburbs, already, it is plain, thickly inhabited.
Thrasybulus yielded to the common action of Siceliots and Sicels.
Iib) we learn that Thrasybulus evidently was deliberately aiming at a renewal of the empire, though the circumstances leading to his death at Aspendus when seeking to raise money suggest that he had no general backing in Athens.
