Mesopotamia (Sumer/Babylon)

Mesopotamia (Sumer, Babylon, Assyria) pioneered humanity's first written code of laws—Hammurabi's Code, with 282 laws—and cuneiform, the earliest writing system (circa 3400 BC), making it the benchmark for recorded history. It produced base-60 mathematics, still used for time and angles, and the Epic of Gilgamesh, the oldest known story—predating Homer by over 1,500 years. While Ancient Egypt surpassed it in monumental architecture, Mesopotamia's innovations in cities (Ur, Babylon), organized religion, and law set the foundation for all subsequent civilizations. Its data point: the first legal code predates Rome's Twelve Tables by 1,200 years, establishing a 30% earlier framework for justice.
