Classical Age
Refounded around 545 BCE by refugees from Ionian Teos fleeing Persian conquest, Abdera grew rich on trade and joined the Athenian-led Delian League after the Persian Wars. It became famous as the home of Democritus, who with his teacher Leucippus held that all things are made of indivisible atoms moving through the void, and of Protagoras, the first and greatest of the sophists, who declared that 'man is the measure of all things' and taught for fees across the Greek world.
