Quick questions on Transformation of the Delian League into the Athenian Empire: HSC Ancient History

In 454 BC the Athenians moved the treasury of the Delian League from Delos to the Opisthodomos of the temple of Athena on the Acropolis. The official reason was the Persian threat to Delos after the Egyptian disaster. The practical effect was that:

A negotiated peace, brokered by the Athenian Callias son of Hipponicus, ended formal hostilities between Athens and Persia. The terms (as reconstructed):

The Athenian Coinage Decree (the precise date is contested, ranging from 449 to 414 BC, with the 420s BC most likely on Lewis's epigraphic evidence) ordered the allied cities to use Athenian coinage, weights, and measures. Allied silver coinage was banned; cities had to bring their silver to the Athenian mint. The decree imposed Athenian commercial standards across the empire.

Cleruchies were settlements of Athenian citizens on land confiscated from allied or hostile states. The cleruchs retained Athenian citizenship and the land allotment was a form of paid garrison.

The major revolt of the late 440s BC. Samos was one of the few remaining ship-providing allies (rather than tribute payer). It revolted in 440 BC, partly over a dispute with Miletus and partly over Athenian intervention to install a democracy. Pericles personally commanded the siege.

The first revolt of an ally. Naxos attempted to secede from the League. Cimon led the fleet that reduced Naxos by siege.

Thasos revolted over Athenian seizure of its mainland mining and trading interests at Eion. The siege lasted three years. Cimon reduced the city; the walls were torn down, the fleet handed over, the mining revenues forfeited, and an annual tribute imposed.

Allied tribute (phoros) was paid into the Athenian treasury.

One sixtieth of the tribute was reserved for Athena and recorded annually in the Athenian Tribute Lists. The lists are the documentary foundation of the empire from 454 BC.

Inscribed on a great marble stele (the first stele covered 454 to 440 BC; later stelae continued). The lists name each tributary city and the aparche it paid each year. From the lists modern historians reconstruct around 200 to 400 members and around 400 to 600 talents of annual tribute.

Surplus tribute funded the Parthenon (447 to 432 BC), the Propylaea, the Erechtheion, and other Athenian projects. Plutarch (Pericles 12) records the conservative protest led by Thucydides son of Melesias that Athens was "decking herself out like a vain woman with our allies' money."

Lemnos and Imbros (early), Naxos (after the revolt), Andros, Eretria, Chalcis (after the Euboean revolt of 446 BC), Hestiaia (replacing the population of Hestiaea after the same revolt), Brea in Thrace (around 446 BC).

Athenian "inspectors" sent out to allied cities to supervise loyalty and finance.

Athenian governors installed in some cities (especially after revolts).

Athenian soldiers in key cities.
