After the entry in the 2nd Athenian Confederacy in 377 BC, the Thassians used the support of Athens to extend their influence in the main land. In 357 or 340 BC, King Philippos of Macedonia expands in the neighbouring area. Under the kingship of the Macedonians, Thassos maintains a part of its autonomy.
According to an ancient Greek tradition, goddess Demetra was born in Thassos and taught there for the first time the art of agriculture. The most familiar history of Thassos starts with its colonization. However, there are two different views about who were the first inhabitants of the island.
According to Greek mythology, the first inhabitant and founder of the island, was a namesake man called Thassos. Thassos was either the son or the grandson of Aginoras, King of Phoenicia, who turned up in Thassos while trying to find Europa who had been kidnapped by Zeus in virtue of his passionate love.
During the period of the 1821 revolution, Thassos breathed a short period of freedom, when the Greeks arrived to the island and the tzormpatzis was set head of the revolutionary movement. The Turks were defeated and expelled to Kavala. However, this did not last long, because the fear of pirates led the Thassians to seek help from the passa of Thessalonici.
