2.1 Urbanisation in Southern Mesopotamia: Temples and Kings

Settlements began appearing across southern Mesopotamia from around 5000 BCE. Not every village turned into a city — but a few did, and their growth followed two distinct paths. Some grew up around temples^?; others arose as centres of trade. (Imperial cities, founded later by conquerors, are a third type.) The earliest temples were small mud-brick shrines, the imagined dwelling places of gods such as the Moon God of Ur and Inanna, the Goddess of Love and War.

The temple did far more than host worship. It was theoretically the owner of the local fields, fisheries and herds. Its courtyards and outer rooms doubled as workshops where oil was pressed, grain ground, wool spun and cloth woven. The temple kept written records of every sack of grain or jar of beer paid to a worker. Acting as employer, banker, granary and shrine, the temple gradually became the central institution of urban life.

By 3000 BCE the city of Uruk in the deep south had grown to a staggering 250 hectares — twice the size that Mohenjo-daro would reach centuries later. By 2800 BCE Uruk had expanded again to 400 hectares and acquired a defensive wall. Dozens of small villages around it were abandoned: people had been pulled, or pushed, into the rising metropolis. The poem of Enmerkar (read in Part 1) suggests that this concentration of population was both protected by the king and useful to him — a city-sized population could be levied for armies, for temple-building and for canal-clearing.

War captives and the local poor were drafted to work for the temple or directly for the king — paid not in coins (which did not yet exist) but in rations of grain, oil and cloth. Hundreds of clay tablets list ration recipients by name. One temple, archaeologists estimate, took 1,500 men working 10-hour days for five years to build. Uruk around 3000 BCE also delivered three technological landmarks: bronze tools for woodwork and stone-cutting, brick columns to support the heavy roofs of large temple halls, and the potter's wheel^? — which let a single workshop mass-produce dozens of identical pots a day.

2.2 Life in the City — A Walk Through Ur

Royal tombs at Ur dazzled their excavators with gold, lapis-lazuli jewellery, ceremonial daggers and shell-inlaid musical instruments — proof that a tiny ruling elite controlled most of the city's wealth. But what of ordinary people? Legal texts (about disputes, inheritance and marriage) and the careful 1930s excavation of Ur's residential streets allow us to reconstruct everyday life.

2.2.1 The Streets and Houses of Ur

Ur's residential quarter, excavated in the 1930s, surprised archaeologists. Its streets were narrow, winding and irregular — too tight for wheeled carts, so grain and firewood had to arrive on donkey-back. There was no town-planning grid like the orderly streets of Mohenjo-daro. There were also no street drains. Instead, every house had its own clay-pipe drain in the inner courtyard; rainwater ran off inward-sloping roofs and disappeared into a covered sump.

And yet — household refuse was tossed straight into the street, to be trodden underfoot by passers-by. Street levels rose over decades, forcing residents to keep raising their thresholds so that mud would not flow indoors after heavy rain. Daylight came not through windows (the walls were blank to the street, for privacy) but through doorways into courtyards. Tablets even record house-superstitions: a raised threshold meant wealth; a front door opening directly onto a neighbour's was unlucky; and if the main door swung outwards, "the wife would torment her husband"!

2.3 A Trading Town in a Pastoral Zone — Mari

After 2000 BCE, far from the fertile southern plain, the royal city of Mari^? flourished on the middle Euphrates. Mari did not depend on grain alone. Most of its territory was given over to sheep and goat pasture, with farming squeezed into the river valley itself. This was a mixed-economy kingdom in which farmers and pastoralists lived side by side — sometimes peacefully exchanging meat, leather and manure for grain and metal tools, sometimes clashing over grazing rights and water access.

The kings of Mari were Amorites, a pastoral people who had moved into the plains from the desert margins. Their dress differed from that of the original Sumerian inhabitants. They worshipped both the gods of Mesopotamia and their own pastoral god Dagan, for whom they raised a temple in Mari itself. The historian's lesson is clear: Mesopotamian civilisation was not closed; it was constantly refreshed by people from outside the alluvial plain. This intermixture is what gave Mesopotamia its long-running cultural vitality.

Mari's wealth came not from a powerful army but from its strategic position as a tax-collecting riverport. Even when a kingdom was militarily weak, control of trade could make it spectacularly rich — a lesson repeated centuries later by the Phoenician city-states, the Italian republics and the Indian Ocean ports of medieval Gujarat.

2.4 Cities in Mesopotamian Culture — The Gilgamesh Lesson

Mesopotamians valued city life so highly that when their cities were destroyed in war, poets composed laments to remember them. The most famous testament to this urban pride comes at the end of the Epic of Gilgamesh^?, a cycle of twelve cuneiform tablets recounting the deeds of a legendary king of Uruk. Gilgamesh travelled to the ends of the earth searching for immortality after his closest friend died. He failed. Returning home defeated, he found consolation by walking along the great walls of Uruk and admiring the fired bricks he had laid into them. The poem closes with him taking pride in the city his people had built, not in dynastic descent. For Mesopotamians, the city — not the family or the tribe — was the durable monument.

2.5 The Legacy of Writing — Science, Time and Number

Stories can travel mouth to mouth, but science needs written texts that scholars can re-read and build upon. This is Mesopotamia's most lasting gift to the world. Tablets from around 1800 BCE preserve multiplication and division tables, square and square-root tables, and tables of compound interest. The square root of 2 is given as:

The true value is 1.41421356 — Mesopotamian mathematicians achieved six-decimal accuracy 3,800 years ago, working entirely in their distinctive base-60 number system. That same base-60 is why we still divide an hour into 60 minutes, a minute into 60 seconds, and a circle into 360 degrees today.

2.5.1 Mesopotamia's Astronomers and Their Records

Solar and lunar eclipses were noted by year, month and day. Stars and constellations were tracked night after night. None of this would have been possible without the scribal schools — urban institutions where boys laboriously copied earlier tablets, learnt Sumerian even after it had ceased to be spoken (a status comparable to Latin in medieval Europe), and graduated either as administrators or as scholar-intellectuals who could build on earlier knowledge.

2.5.2 An Early Library — Assurbanipal of Nineveh

Assurbanipal (668–627 BCE), the last great Assyrian emperor, sent scribes south to Babylonia to find old tablets and ordered fresh copies made of important works including the Epic of Gilgamesh. His library at Nineveh held about 1,000 distinct texts on some 30,000 tablets, organised by subject — a basket might be labelled "n number of tablets about exorcism, written by X". This is the world's earliest catalogued library.

2.5.3 An Early Archaeologist — Nabonidus of Babylon

The Babylonian king Nabonidus (6th century BCE) was so interested in his ancestors that we can fairly call him the world's first archaeologist. Wanting to install a high priestess for the Moon god of Ur, he searched ancient stelae until he found one from c. 1150 BCE depicting the priestess's correct dress; he then dressed his daughter accordingly for the consecration. On another occasion his men brought him a broken statue inscribed with the name of Sargon of Akkad (c. 2370 BCE) — a king already over 1,800 years dead. Nabonidus had a craftsman repair the head "out of reverence for the gods and respect for kingship". The Mesopotamian preoccupation with their own past, in other words, is not a modern phenomenon.
