Babylon means "babilu" (gate of god). It is an ancient city in the plain of shinar on the Euphrates River, about 50 miles south of Modern Baghdad. Babylon was founded by Nimrod of Gen. 10, who developed the world's first organized system of idolatry, which God condemned (Gen. 11). It later became the capital of Babylonia and the Babylonian Empire. It was of overwhelming size and appearance.
