Sixth Grade Social Studies: Sumerian City-States, Ziggurats, and Daily Life
Around 3,500 BCE, the world's first true urban civilization arose in southern Mesopotamia: the civilization of Sumer.
The Rise of Sumerian City-States
The Sumerians transformed the marshes and plains of Lower Mesopotamia into vibrant urban centers. Rather than forming a single unified nation, Sumer consisted of numerous independent city-states, including Ur, Uruk, Eridu, Lagash, Nippur, and Kish.
Definition and Anatomy of a City-State
A city-state was an independent political unit consisting of a walled central urban core and the surrounding countryside, farmlands, and satellite hamlets that supported it. Each city-state had its own ruler, its own patron god or goddess, its own military force, and its own legal customs.

| [ AGRICULTURAL SURROUNDINGS ] |
| - Irrigated barley fields, date palm orchards, sheep grazing pastures |
| - Peasant hamlets and irrigation canal locks |

| [ DEFENSIVE CITY WALLS ] |
| - Thick sun-dried mud-brick fortifications with fortified towers & gates|
| |
| [ URBAN RESIDENTIAL QUARTERS ] |
| - Narrow, winding unpaved alleys; tightly packed mud-brick homes |
| - Artisan craft quarters: potters, weavers, metalsmiths |

| [ SACRED PRECINCT (TEMENOS) ] |
| - Monumental Ziggurat dedicated to city's patron deity |
| - Royal Palace (*Egal*), administrative granaries, scribe schools |

Inter-City Conflict and Fortifications
Because farmland, water rights, and irrigation boundaries were limited, neighboring city-states frequently waged war against one another. For instance, the long-running war between Lagash and Umma over fertile border territory lasted for generations. Due to chronic military conflict, every Sumerian city was encircled by massive perimeter walls made of sun-dried mud bricks, reinforced with watchtowers and protected gates.
The Ziggurat: Architectural and Spiritual Heart
At the absolute physical and administrative center of every Sumerian city rose the ziggurat—a monumental stepped pyramid constructed of sun-dried mud bricks.
Architecture of the Ziggurat
Unlike Egyptian pyramids, which were tombs with interior burial chambers ending in a sharp peak, a ziggurat was a solid mountain of earth and mud brick with an exterior staircase leading to a flat summit. The exterior facade was faced with fire-baked bricks set in bitumen (natural asphalt) to resist water damage. At the flat summit stood a shrine or temple dedicated to the city's patron deity—such as Nanna (the moon god) at Ur, or Inanna (goddess of love and war) at Uruk.

Religious and Economic Functions
The Sumerians believed that the gods lived on high mountain peaks; because southern Mesopotamia was flat, the ziggurat functioned as an artificial mountain connecting heaven and earth (axis mundi). Priests climbed the monumental staircases to make animal sacrifices, pour libations, and burn incense to appease the deities. Economically, the ziggurat complex served as the civic redistribution center. Priests collected agricultural taxes (grain, wool, cheese, and beer), storing food in massive temple granaries to feed craftsmen and distribute to the public during famines.
Sumerian Governance: From Priests to Kings
The political structure of Sumer evolved over centuries in response to military crises.
Theocratic Rule: En and Ensi
Originally, Sumerian cities were theocracies—governments ruled by religious leaders claiming divine authority. The chief priest, known as the En, oversaw temple land, managed agricultural irrigation, and coordinated communal labor. A civil governor, known as the Ensi, represented the patron god on Earth and executed civic administration.
The Rise of the Lugal (King)
As wars between city-states became frequent and destructive, cities required decisive military leadership during emergencies. City councils selected a military warlord, titled the Lugal (literally "Big Man"). Over time, these temporary wartime commanders refused to relinquish power after victories, establishing permanent hereditary dynasties and moving political administration from the temple to the royal palace (Egal).

Daily Life, Social Classes, and the Household
Sumerian society was stratified into distinct social tiers, each with defined duties, privileges, and living conditions.
Social Stratification
At the top of the social hierarchy stood the Lugal and his royal family, followed closely by high priests and military commanders. The upper class consisted of government scribes, district governors, and landed aristocrats. The middle class was composed of free merchants, traders, jewelers, carpenters, and potters. The broad base of society consisted of peasant farmers and herders who tilled temple lands or family plots. At the bottom were enslaved persons—either prisoners captured in wars against neighboring cities or citizens forced into temporary servitude to pay off debts.
Housing and Domestic Living
Ordinary Sumerian families lived in single- or two-story flat-roofed homes built of mud brick. Homes lacked external windows facing the street to block out street dust and blinding solar heat; instead, rooms opened inward onto a central sunlit open courtyard. Thick mud-brick walls provided insulation against extreme daytime temperatures. People slept on the flat roofs during stifling summer nights. Diets consisted primarily of barley bread, mashed chickpea and lentil stews, onions, dates, dried fish, and low-alcohol barley beer, which was safer to drink than untreated river water.
Review Exercises
Exercise 1: Define what a Sumerian city-state was, and explain why Sumerian cities were surrounded by massive mud-brick fortification walls.
Exercise 2: Describe the architectural design, religious purpose, and economic role of a Sumerian ziggurat.
Exercise 3: Explain the political transition in Sumerian governance from rule by religious priests (the En) to hereditary kings (the Lugal).
Solutions
Solution 1: A Sumerian city-state was an independent sovereign political territory consisting of a walled city center surrounded by outlying farmlands, orchards, and villages under the control of its own government. Sumerian city-states built thick mud-brick perimeter fortification walls because neighboring cities constantly fought one another over access to irrigation water, arable border farmland, and valuable trade routes.
Solution 2: Architecturally, a ziggurat was a monumental stepped mud-brick pyramid with terraces ascending to a flat platform topped by a temple shrine. Religiously, it was conceived as an artificial sacred mountain connecting heaven and earth, providing a dwelling place where priests made sacrifices to appease the city's patron deity. Economically, the ziggurat complex contained temple granaries and warehouses that collected, stored, and redistributed tax grain, wool, and oil to feed specialized craftsmen and support citizens during droughts.
Solution 3: In early Sumerian history, priests (En) held primary authority because communities believed success depended on appeasing the gods through religious rituals. However, as warfare between rival city-states escalated, cities appointed temporary military commanders called Lugals ("Big Men") to lead armies during wars. Because military threats were constant, these warlords accumulated wealth, commanded loyal armed troops, centralized administration in their royal palaces, and transformed temporary military appointments into hereditary dynastic monarchies.
