Title: Babylon
Content:  "Babilu" redirects here. It is not to be confused with Babalu. For other uses, see Babylon (disambiguation). Babylon was the ancient city where some of the most influential empires of the ancient world ruled. It was the capital of the Babylonian Empire and it was considered to be a center of commerce, art, and learning and is estimated to have been the largest early city in the world, perhaps the first to reach a population above 200,000. Presently it is an archeological site and only has several thousand residents and a few villages within the archeological boundaries, although constructions have increased rapidly in recent years with some encroaching on the ruins. The archeological site lies approximately 85 kilometers (53 mi) south of present-day Baghdad in Hillah, Babil Governorate, Iraq, and its boundaries have been based on the perimeter of the ancient outer city walls, an area of about 1054.3 hectares. Babylon was inscribed by UNESCO as a World Heritage site and receives thousands of visitors each year, almost all of which are Iraqis.

Under Cyrus and the subsequent Persian king Darius I, Babylon became the capital city of the 9th Satrapy (Babylonia in the south and Athura in the north), as well as a center of learning and scientific advancement. In Achaemenid Persia, the ancient Babylonian arts of astronomy and mathematics were revitalized, and Babylonian scholars completed maps of constellations. The city became the administrative capital of the Persian Empire and remained prominent for over two centuries. Many important archaeological discoveries have been made that can provide a better understanding of that era. 
Title: Babil Governorate
Content:  The ancient city of Babylon in present-day Babylon Province was the capital of ancient Babylonia, situated on the Euphrates river south of Baghdad, Iraq. The city was occupied from the 3rd millennium BC but became important early in the 2nd millennium under the kings of the First Dynasty of Babylon. The sixth king of this dynasty was Hammurabi (1792–1750 BC) who made Babylon the capital of a vast empire and is best remembered for his code of laws. The city achieved pre-eminence when Nebuchadnezzar II (605–562 BC) extended the Babylonian Empire over most of Western Asia. Bestowing this name on the province is a manifestation of the policy of modern Iraq to link itself to the history of pre-Islamic Mesopotamia. In 1991 Babil Governorate was the center of a Shia uprising.
Title: Hillah
Content:  Located just 5 km (3.1 mi) north of the city of Hillah, Babylon was a marveled city of the ancient world, especially under the rule of king Nebuchadnezzar (605–562 BC). It was the capital of the Neo-Babylonian Empire and its walls and hanging gardens were considered one of the seven wonders of the world.

Content:  Under Nabopolassar, a previously Chaldean King, Babylon escaped Assyrian rule, and in an alliance with Cyaxares, king of the Medes who was his son in law together with Cimmerians, finally destroyed the Assyrian Empire between 612 BC and 605 BC. Babylon thus became the capital of the Neo-Babylonian (sometimes called the Chaldean) Empire. With the recovery of Babylonian independence, a new era of architectural activity ensued, particularly during the reign of his son Nebuchadnezzar II (604–561 BC). Nebuchadnezzar ordered the complete reconstruction of the imperial grounds, including the Etemenanki ziggurat, and the construction of the Ishtar Gate—the most prominent of eight gates around Babylon. A reconstruction of the Ishtar Gate is located in the Pergamon Museum in Berlin. Nebuchadnezzar is also credited with the construction of the Hanging 
Title: Babylonia
Content:  Babylonia was an ancient Akkadian-speaking state and cultural area based in central-southern Mesopotamia (present-day Iraq and Syria). A small Amorite-ruled state emerged in 1894 BC, which contained the minor administrative town of Babylon. It was merely a small provincial town during the Akkadian Empire (2335–2154 BC) but greatly expanded during the reign of Hammurabi in the first half of the 18th century BC and became a major capital city. During the reign of Hammurabi and afterwards, Babylonia was called "the country of Akkad" (Māt Akkadī in Akkadian), a deliberate archaism in reference to the previous glory of the Akkadian Empire.
