Sumer
4500 – 1900 BCE
Cities, cuneiform, and the earliest written administration on record.
Every claim in this period carries its evidence with it.
Tens of thousands of cuneiform tablets, excavated city plans, temple and palace archives, and the material record of southern Mesopotamian mounds.
- 01
Writing appears here first as administrative accounting, then broadens into law, literature and letters.
- 02
Urbanism at scale — walled cities with temple institutions and specialised labour — is documented in the material record.
- 03
Sumerian is a language isolate, deciphered through bilingual texts with Akkadian.
Each row states the method, what is actually measured, and — the part usually skipped — what the result does not settle.
| Method | Material | What it constrains |
|---|---|---|
| Epigraphy and archival analysis | Administrative and literary cuneiform tablets | Gives direct testimony from the period. Archives record what institutions chose to record. |
| Stratigraphic excavation | Tell sequences at southern Mesopotamian city sites | Establishes phasing and destruction events; absolute dates need external anchors. |
| Astronomical and king-list synchronisms | Dated observations and regnal lists cross-checked against other archives | Builds the chronology framework. Competing high, middle and low chronologies still coexist. |
Which absolute chronology is correct?
High, middle and low schemes differ by roughly a century for the third and second millennia.
How centralised were early temple economies?
The 'temple city' model has been substantially revised toward mixed household and institutional economies.
“The Sumerian King List is a straight history.”
It is a political document with reigns of implausible length; it mixes tradition with legitimation.
“Sumer is the single origin of all civilisation.”
It is the earliest well-documented urban literate society, which is not the same claim.
- How did the earliest proto-writing tokens become a full script?
- What was the demographic scale of the largest cities?
- How much of the archive record survives versus what was written on perishable media?
