The first inhabitants of Sifnos were the Pelasgians, followed by the Cretans. The island experienced great growth during the Early Cycladic era, but also during the Mycenaean Age. The Archaic years were one of the richest islands of the Cyclades due to its gold mines, silver mines and quarries. After the Persian Wars, Sifnos became a member of the Athenian Alliance. It was followed by Roman times and the Byzantine era and during Sultanate, Sifnos became a member of the Duchy of the Aegean. In 1307 Sifnos captured the Spanish Giannoulis Da Coronda, who belonged to the Order of the Knights of Rhodes. In 1464 Sifnos was commanded by the family of Gödzantini until 1566 when the Ottomans conquered it.
