The ancient city of Byzantium was founded by Greek colonists from Megara around 657 BCE. According to the historian Tacitus, it was built on the European side of the Strait of Bosporus on the order of the “god of Delphi” who said to build “opposite the land of the blind”. This was in reference to the inhabitants of Chalcedon who had built their city on the eastern shore of the Strait; the west side was considered far more fertile and better suited for agriculture.

The following year Byzantium faced a threat from the Thracians to the west and sought help of Sparta who took control of the city. Around 390 BCE the city changed hands again when the Athenian general Thrasybulus ended Spartan
