Around 4000 BCE, in the land between the Tigris and Euphrates, something extraordinary began. In the fertile plains of Mesopotamia, people who had once wandered with their herds started to settle. They dug irrigation canals, learned to tame the rivers, and turned wild floodplains into fields of grain. This abundance allowed them to do something no human community had done before: build cities.
Uruk, Ur, and Eridu rose from the earth as clusters of mudbrick houses surrounding monumental temples that reached toward the heavens. Within these walls, tens of thousands of people lived, traded, worshiped, and recorded their lives on clay tablets. Priests managed temples that doubled as banks. Scribes invented cuneiform, the first writing system, to keep track of goods, debts, and stories. In these early city-states, religion, economics, and politics fused into a single system that bound people together under shared gods and common rules.

Uruk, the city of the legendary King Gilgamesh, became the greatest of them all. It was a marvel of human cooperation, a living machine powered by belief and bureaucracy. Here, the first seeds of government and social order were planted. Humanity was learning how to live together in large numbers, how to organize, and how to rule.
The temples became the beating hearts of these new cities. Grain poured into their storehouses as offerings to the gods, and from there it was measured, counted, and redistributed to workers and farmers. Clay tablets, etched with symbols of barley and goats, were humanity’s first ledgers. The act of worship became inseparable from the act of accounting. To serve the gods was also to balance the books.
And so the first taxes were born, not coins or bills, but baskets of wheat, jars of oil, and flocks of sheep given in tribute to the divine order. What began as devotion turned into administration. What was once a prayer became a receipt. The temple, with its scribes and seals, transformed faith into an early form of governance, ensuring that every harvest, every debt, and every duty was written into the memory of clay.
A few centuries later, in Babylon, another great leap took place. Around 1754 BCE, King Hammurabi had his laws carved into a black basalt pillar more than seven feet tall. The Code of Hammurabi was one of the first written attempts to define justice. It spoke of property, wages, marriage, and trade, and of the idea that punishment should fit the crime, “an eye for an eye, a tooth for a tooth.” Though harsh by modern standards, it represented a profound shift: the belief that order should rest not on the whim of rulers, but on a system of laws.
Hammurabi’s code introduced principles that still echo today. It recognized evidence, judgment, and accountability. It imagined a society governed by reason rather than power alone. Copies of the code stood in temples across the empire, a public promise of fairness, even if few could read it.
The legacy of Mesopotamia is not merely its bricks or its gods, but its ideas. From the walls of Uruk to the laws of Hammurabi, the people of this ancient land built the foundations of civilization itself, the city, the state, and the rule of law. In their clay tablets and carved stones, we can still trace the first lines of the human story we are all part of today.
