The Babylonians lived in the city of Babylonia, based in central-southern Mesopotamia. This city was located on the River Euphrates in what is now known as southern Iraq. The city first came into prominence as the royal city of king Hammurabi around the year 1790 BC.
The Babylonians built an empire that gave the world the Hanging Gardens of Babylon, one of the Seven Wonders of the World. They also constructed the Tower of Babel. This tower, made of baked brick, was a ziggurat created as a place of worship. The Babylonians are also credited with giving the world codified laws.
