(477 - 404 BC), Paros paid the highest tribute of the island members: 30 talents annually, according to the estimate of Olympiodorus (429 BC). This implies that Paros was one of the wealthiest islands in the Aegean. Little is known about the constitution of Paros, but inscriptions seem to show that it was modeled on the Athenian democracy, with a boule (senate) at the head of affairs. In 410 BC, Athenian general Theramenes discovered that Paros was governed by an oligarchy; he deposed the oligarchy and restored the democracy. Paros was included in the second Athenian confederacy (the Second Athenian Empire 378 - 355 BC). In c. 357 BC, along with Chios, it severed its connection with Athens.
From the inscription of Adule, it is understood that the Cyclades, which are presumed to include Paros, were subjected to the Ptolemies, the Hellenistic dynasty (305 - 30 BC) that ruled Egypt. Paros then became part of the Roman Empire and later of the Byzantine Empire, its Greek-speaking successor state.
Crusades
In 1204, the soldiers of the Fourth Crusade seized Constantinople and overthrew the Byzantine Empire. Although a residual Byzantine state known as the Empire of Nicaea survived the Crusader onslaught and eventually recovered Constantinople (1261), many of the original Byzantine territories, including Paros, were lost permanently to the crusading powers. Paros became subject to the Duchy of the Archipelago, a fiefdom made up of various Aegean islands ruled by a Venetian duke as nominal vassal of a succession of crusader states. In practice, however, the duchy was always a client state of the Republic of Venice.
Ottoman Era and independence
In 1537, Paros was conquered by the Ottoman Turks and remained under the Ottoman Empire until the Greek War of Independence (1821–1829). During the Russo-Turkish War (1768–1774) in 1770–1775 Naoussa Bay was the home base for the Russian Archipelago Squadron of Count Alexey Orlov
