Babylonian Empire Rises

Around 1800 BCE, the city of Babylon, on the Euphrates River in what is now Iraq, was still one of several competing city-states in Mesopotamia. Within a few decades it became the center of a powerful kingdom that dominated most of the region. The rise is usually associated with Hammurabi, who reigned in the 18th century BCE, though the precise dates of his rule are debated because Mesopotamian chronologies rest on competing reconstructions. Babylon's political and cultural prestige outlasted its power, and the city remained a symbol of Mesopotamian civilization for well over a thousand years.

The background was a fragmented landscape. After the collapse of the Third Dynasty of Ur around 2000 BCE, southern and central Mesopotamia split among rival cities such as Isin, Larsa, Eshnunna, and Mari. Many ruling families were of Amorite origin, descendants of West Semitic–speaking groups who had settled in the region and adopted its customs. Babylon's own Amorite dynasty had been founded a couple of centuries earlier, but for generations its kings ruled a relatively modest territory.

Hammurabi, the sixth king of this dynasty, transformed that position through a mix of diplomacy, alliances, and war. Records, including the year-names by which his reign was dated, show him building canals, fortifying cities, and campaigning against neighbors. He is generally credited with defeating Larsa, the dominant power of the south, and later bringing Mari and other northern centers under his control. At its height his realm covered much of southern and central Mesopotamia, though it was never as large or as tightly governed as later empires, and control over distant areas likely varied.

Hammurabi is best remembered for the law collection inscribed on a black basalt stele, now in the Louvre. It lists dozens of legal rulings, many framed as "if a man does this, then this follows," and it was introduced by a prologue presenting the king as a just ruler chosen by the gods. Scholars debate whether it was a true legal code applied in courts or more an expression of royal ideals, since surviving legal documents do not always match its provisions. Even so, it offers a rare view of social hierarchy, property, family, and commerce in the ancient world.

The empire proved fragile. Under Hammurabi's successors, southern territories broke away, and Babylon's power waned. Hittite forces under Mursili I sacked the city around 1600 BCE, a date also uncertain, and the dynasty ended. Yet the Babylonian language, scholarship, literature, and law shaped the region for centuries, and Babylon later rose again as the capital of new empires.
