Byzantium
Though Istanbul may have been inhabited as early as 3000 BCE, it was not a city until Greek colonists arrived in the area in the 7th Century BCE. These colonists were led by King Byzas and settled there because of the strategic location along the Bosporus Strait. King Byzas named the city Byzantium after himself.
The Roman Empire (330-395 CE)
Following its development by the Greeks, Byzantium became a part of the Roman Empire in the 300s. During this time, the Roman emperor Constantine the Great undertook a construction project to rebuild the entire city. His goal was to make it stand out and give the city monuments similar to those found in Rome. In 330, Constantine declared the city as the capital of the entire Roman Empire and renamed it Constantinople.
