. 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 of Theophilos Kairis. Psara remained in the hands of the
Ottomans until it was recaptured by the
Greek navy on 21 October 1912 during the
First Balkan War. ==Historical population==
