Babylonia(Babel)

Babel was founded by Nimrod

Gen 10:10  And the beginning of his kingdom was Babel, and Erech, and Accad, and Calneh, in the land of Shinar. 

Tower of Babel begins

(Gen 11:3)  And they said one to another, Go to, let us make brick, and burn them throughly. And they had brick for stone, and slime had they for morter.

(Gen 11:4)  And they said, Go to, let us build us a city and a tower, whose top may reach unto heaven; and let us make us a name, lest we be scattered abroad upon the face of the whole earth.

God ceases work on Tower

(Gen 11:5)  And the LORD came down to see the city and the tower, which the children of men builded.

(Gen 11:6)  And the LORD said, Behold, the people is one, and they have all one language; and this they begin to do: and now nothing will be restrained from them, which they have imagined to do.

(Gen 11:7)  Go to, let us go down, and there confound their language, that they may not understand one another's speech.

(Gen 11:8)  So the LORD scattered them abroad from thence upon the face of all the earth: and they left off to build the city.

(Gen 11:9)  Therefore is the name of it called Babel; because the LORD did there confound the language of all the earth: and from thence did the LORD scatter them abroad upon the face of all the earth.

Babylon

Babylon was a small, obscure city-state until King Hammurabi (1792-1750 BC) chose it as his capital, expanding the empire that became Babylonia. Located about 59 miles southwest of modern Baghdad, Babylon was laced with an intricate system of canals leading off the Euphrates River, used for irrigation and commerce.

Historians believe Babylon was the first ancient city to exceed 200,000 people. The city proper measured four square miles, on both banks of the Euphrates. Much of the building was done during the reign of King Nebuchadnezzar, referred to in the Bible as Nebuchadnezzar. He built an 11-mile defensive wall outside the city, wide enough on top for chariots driven by four horses to pass each other. Nebuchadnezzar was the last truly great ruler of Babylon.
