The island of Paros has been inhabited since 3200 BC as are proving the excavations made on the islet of Saliagos, located between Paros and Antiparos. It probably formed one single island during ancient times, and seperated during an earthquake. Mythology tells us that King Alkaios of Crete was the first king, and that he build a city on the site of which is today known as the capital Parikia . Then fertile Paros was strategically positioned in the middle of the Cyclades. The Cretans turned it into a naval basis. In 1100 BC the Ionians defeated the Cretan Minoans and took over the rule of the island. In 1000 BC, Paros was taken by the Arcadians, that were lead by Parios, from who the island took its definitive name. After that the island became a maritime power. Part of the army of Paros army fought with the Persians, during the Persian wars, and were defeated by the Athenian army. In 338 BC, like all the Greek islands, Paros came under the rule of Philippe of Macedonia and became part of the Macedonian empire. When Alexander the Great (Philippes son) died, Paros came under the control of the Egyptian Ptolemies, Alexanders successors.

The faith of the Greek islands is pretty much the same on each of them. The Romans took over the island, and after them the Byzantines. They brought Christianity to the island and build many churches, amongst which the most important monument from that period in Greece: the Church of Ekatontapiliani in Parikia. Between 1207 and 1389 Paros was ruled by the Venetians and after them by the Ottoman Turks. After de Greek revolution in 1821 Paros became part of the new Greek State.
