Babylon - A settlement in Babylonia
Babylon was a key city and kingdom in ancient Mesopotamia from the 18th to 6th centuries BC. The city was built on the Euphrates river and divided in equal parts along its left and right banks, with steep embankments to contain the river's seasonal floods. Babylon was originally a small Akkadian town dating from the period of the Akkadian Empire c. 2300 BC.

The Hanging Gardens of Babylon was one of the Seven Wonders of the Ancient World, although a number of scholars believe these were actually in the Assyrian capital of Nineveh. After the fall of the Neo-Babylonian Empire, the city came under the rule of the Achaemenid, Seleucid, Parthian, Roman, and Sassanid empires.

It has been estimated that Babylon was the largest city in the world from c. 1770 – c. 1670 BC, and again between c. 612 – c. 320 BC. It was perhaps the first city to reach a population above 200,000.
