Mesopotamia & Sumer

I. Overview

Mesopotamia — Greek for “between the rivers” — is where civilization as we know it began. Around 4000 BC the marshy plain of Sumer (southern Iraq) held the worldʼs first cities: Uruk with 50,000 people and a 9-km wall, Ur, Eridu, Nippur. Here scribes pressed reed styluses into clay to invent cuneiform writing (c. 3400 BC), pottersʼ wheels became transport wheels, sails caught the Gulf wind, bronze was smelted, and mathematicians counted in base sixty — giving us the 60-minute hour and 360-degree circle (WHE, “Mesopotamia”; Britannica).

Sumerian city-states — Lagash, Umma, Kish, Uruk — warred for water and kingship, recorded on the Stele of the Vultures and the Standard of Ur. Then Sargon of Akkad (c. 2334–2279) conquered them all — historyʼs first empire, from the Gulf to the Mediterranean. His grandson Naram-Sin declared himself a god; the Gutians brought Akkad down. Ur-Nammu of Ur (2112–2095) built the great ziggurat still standing and wrote the oldest surviving law code — 300 years before Hammurabi of Babylon (1792–1750) carved his 282 laws on black diorite (WHE, Hammurabi).

Religion centred on ziggurat temples to An, Enlil, Inanna and Marduk; the Epic of Gilgamesh — king of Uruk c. 2700 BC, two-thirds god — is humanityʼs oldest great literature, with its flood story predating Genesis by a millennium. Babylon fell to Persia in 539 BC, but cuneiform was still written in AD 75 — a 3,400-year tradition.

II. Geography

Two rivers, two temperaments: the wild Tigris and slow Euphrates flood violently and shift course — unlike Egyptʼs gentle Nile, forcing constant canal-digging and breeding a worldview of anxious gods. North (Assyria): rain-fed hills. South (Sumer/Babylonia): desert needing irrigation; dates, barley, fish, reeds. No stone, wood or metal — everything imported by Gulf boats and donkey caravans, paid with grain and textiles. Marshes gave reeds for writing, boats and houses (still lived in by Marsh Arabs).

III. Uruk to Sargon

Urukʼs Eanna precinct (c. 3500) held temples on terraces; the Warka Vase shows the king feeding goddess Inanna. Cuneiform began as pictograph tallies, became wedge-signs for Sumerian then Akkadian. Gilgamesh built Urukʼs wall; the Sumerian King List gives him 126 years. Lagashʼs Eannatum (2450) conquered Umma; Lugalzagesi of Umma united Sumer — until cupbearer Sargon of Kish took everything in 2334 and ruled 56 years.

IV. Law, Religion, Science

Ur-Nammuʼs code (c.2100, oldest surviving) fined rather than maimed; Hammurabiʼs 282 laws (c.1754) set “eye for eye” by class. Gods: An, Enlil, Inanna, Enki, Nanna, Utu, Marduk. Ziggurats — staged mountains (Urʼs 30 m survives) — lifted priests to heaven. Priests tracked Venus and eclipses; base-60 gave our minutes and 360-degree circles.
