the voting system conducted by relying on the support of democratic city-states Athens had helped into being. By 454 Athens moved the treasury of the Delian League from the Island of Delos to the Parthenon in Athens. Benefitting greatly from the influx of cash coming out of the 150-330 members, Athens used the money to reinforce its own naval supremacy and used the remaining funds to embellish the city with art and architecture. In order to maintain the new synoecism, Athens began using its greatly expanded military to enforce membership in the League. City-states who wished to leave the alliance were punished by Athens with force such as Mytilene and Melos. No longer considered her allies, Athens eventually began to refer to the members of the Delian League as "all the cities Athens rules." Athens also extended its authority over members of the League through judicial decisions. Synoecism under the Athenian Empire was enforced by resolving matters of and between states in Athens by courts composed of Athenian citizens and enforcing those decisions through the Athenian military. Mytilenean Revolt In 428 BCE Mytilene sought independence from the Athenian Empire by way of a planned revolt. Despite never occurring, the revolt would have placed Mytilene at the centre of Lesbos synoecism in an effort to consolidate political power under the city's control to the extent that the hegemony of Athens could be overthrown. The successful synoecism of Lesbos under Mytilenean oligarchs would have caused Athens to reconsider its relationship with the city due to its central organization of the isle's resources. Unfortunately for Mytilene, Athens learned of this planned synoecism and besieged the city. Victorious Athenians then voted first for the murder of all male citizen and enslavement of women and children only to reverse their decision and committed only the leaders of the revolt. Under increased Athenian rule and observation, Mytilene was subjected to forced synoecism under Athens and its autonomy, curbed. Athenian citizens were sent to Lesbos in order to establish a stronger Athenian presence in Lesbos by collecting taxes from the Lesbians. The city walls of Mytilene were also dismantled under Athenian rule. Dioecism A dioecism is essentially the inverse of a synoecism, the releasing of cities, towns or villages from their association with a polis. This process might manifest itself in several ways, such as the settling of new but independent communities within former territory of Constantinople
