Dionysos () originated from the fact that Psyra was a poor and small island which could not produce its own wine, and was used in reference to people who were reclining at a symposium but not drinking. Another ancient Greek proverb, You regard Sparta as Psyra (), also expressed the poverty of the island. During the middle ages Psara had a very small population, which abandoned the island for Chios after the Fall of Constantinople. In the 16th century, under the Ottoman rule, the Psariots returned to their homeland along with other settlers and established a settlement around the Palaiokastro fort which they repaired. They turned to trade, amassing great profits. By the beginning of the 19th century the Psariots had the third largest trade fleet in Greece after Hydra and Spetses, numbering some 45 ships. Destruction Psara joined the Greek War of Independence on April 10, 1821. Future Prime Minister Konstantinos Kanaris, Dimitrios Papanikolis, Andreas Pipinos and Nikolis Apostolis distinguished themselves as naval leaders, using fire ships to combat the more powerful Ottoman Navy. Psara's native population of people was further augmented by refugees from Thessaly, Macedonia, Chios, Moschonisia and Kydonies. On July 3 (June 21 O.S.), 1824, the island was invaded by the Turks. The resistance of the Psariots ended the next day with a last stand at the town's old fort of Palaiokastro (alternative name Mavri Rachi, literally "black ridge"). Hundreds of soldiers and also women and children had taken refuge there when an Ottoman force of stormed the fort. The refugees first threw a white flag with the words "Ἐλευθερία ἤ Θάνατος" ("Eleftheria i Thanatos", "Freedom or Death"). Then, the moment the Turks entered the fort, the local Antonios Vratsanos lit a fuse to the gunpowder stock, in an explosion that killed the town's inhabitants along with their enemies — thus remaining faithful to their flag to their death. A French officer who heard and saw the explosion compared it to a volcanic eruption of Vesuvius. A part of the population managed to flee the island, but those who did not were either sold into slavery or killed. As a result of the invasion, thousands of Greeks met a tragic fate. The island was deserted and surviving islanders were scattered through what is now Southern Greece. Theophilos Kairis, a priest and scholar, took on many of the orphaned children and developed the famous school the Orphanotropheio
