The first human settlements dates back to 3000 A.C. on the island of Paros. Important testimony of this distant historical period is Saliagos archaeological site. It is a small island located between Paros and Antiparos, whose findings are very interesting and corroborate among others the argument that in ancient times the two islands were united. Paros was anciently called Minoa (a term that comes from the “Minoan Crete” whose inhabitants settled in the island). Later the island was occupied by the Arcadians, the population of Arcadia in the Peloponnese, whose leadership was Parios, from which the island got its current name. The development of Paros was, however, due to the successive colonizers, the Ionians. At the end of the Persian Wars, Paros underwent numerous conquests by the Macedonians and Romans, until it became part of the Byzantine Empire with the consequent conversion to Christianity. In the Byzantine period were built in Paros numerous churches and monasteries, including the famous Cathedral Ekatontapyliani, internationally renowned for its beauty. In 1207 the island of Paros was conquered by the Venetians and later became part of the Duchy of Naxos. In this period an important Catholic community settled in the island. Subsequently, at the end of the Turkish occupation and the Greek War of Independence, the island of Paros was incorporated into the Greek nation along with the rest of the Greek islands.
There are not many information about the history of Antiparos but it is thought to be undoubtedly linked to that of the Paros island. As we have already noted, some experts argue that in ancient times the two islands could have been united, one large separate island then by sea to corrosion or other natural phenomena. To confirm this hypothesis, there are some traces of Neolithic settlements similar to those found in Paros. In the second millennium BC Antiparos was dominated by the Minoan civilization and therefore belonged to the kingdom of Crete which followed its fate. In the thirteenth century the Venetian Maritime Republic conquered most of the islands, including Antiparos and Italian domination continued for three centuries, until conquered by the turkish. The liberation of the island from foreign domination will take place only in the nineteenth century, with the Greek war of independence in 1821 and then the subsequent annexation to the Greek state. During the World War Antiparos was conquered by the Italian soldiers.
