According to tradition, Paxos was once joined to Corfu. Frequent tempests, provoked by Poseidon and Aiolos, gods of the sea and the winds, caused the land to sunder, and from then on Paxos continued to move further away to the south.
Another more romantic version tells us that Poseidon caused the separation of the two islands when he cast his trident into the sea in order to create a peaceful haven where he could enjoy his love affair with Amphitrite. Thus the emblem of Paxos is a trident.
In ancient chronicles, Paxos is mentioned by Herodotus, Polyvio and Plutarch. In 229 BC, just off Paxos, a naval battle between Corfu and Illyria took place, which led directly to the Roman occupation. In 960 AD Bishop Leouprandos visited the island and there wrote his third book of history.
Until 1380, (the Age of the Angevins), the fate of Paxos was closely linked with that of Corfu. But in that year it was granted to Baron Adam Sainte-Hippolyte, and then six years later the Venetians occupied Corfu . The Baron held on to ownership of Paxos as a fiefdom. In 1423, the fortress on the islet of Saint Nicholas at Gaios was built to protect the area from attacks by Turks and pirates. After the death of Sainte-Hippolyte, his sister and heir, Lucentia, married the Sicilian, Ricardo Altavilla, with the island as her dowry. For the 30 years after 1484, Paxos came under the jurisdiction of the Venetian Republic and fell into the hands of the noble Avrami family. The heavy taxes imposed by the landowners and constant pillage by pirates who carried off the populace into slavery, brought the Paxiots to the edge of deprivation. The Venetian period is also characterised by the monoculture of olives, and by the development of commerce through the evolution of a merchant marine fleet.
The story continues with the French Republicans, the Russo-Turkish Alliance, the Septinsular State, and the French again - Imperialists this time. In 1810, the British navy first appeared in the Ionian, seizing Lefkada and threatening the other French-occupied islands. Unrest came to Paxos. Starving from lack of grain, heavily oppressed by the dictatorial authorities, the Paxiots, led by the pirate captain, Kefalas, revolted. They raised the British flag, and slaughtered the French aristocrats, plundering and burning their houses. The French sent a force to suppress the revolt, and the rebels were court-martialled. In 1811, seven of them were executed in Corfu, and their estates confiscated.
Three years later, the British, with the help of Theodoros Kolokotronis, invaded the island and occupied it. During the period they held it, the British constructed waterworks, roads and harbours, and set up schools.
