2340 BC
Akkadian Empire
The king Sargon beat at Ur has a name only because of a caption attached to the victory monuments: Lu-Nanna.

Original prompt & settings (JSON) ↗Uruk, then Ur
c. 2340 BCE conventionally marks the beginning of Sargon's reign — it is the Metropolitan Museum's working date — and the surviving evidence does not date the Uruk campaign to a particular year or day. What the inscriptions preserve is a sequence.
Sargon defeated Uruk and its king Lugalzagesi, who had controlled several Sumerian cities. His victory inscription says the captive king was taken in a neck stock to Enlil's gate at Nippur.
The same campaign text moves on to Ur, whose wall Sargon's forces destroyed. Douglas Frayne identifies its defeated ruler as Lu-Nanna from a caption associated with the conquest monuments.
One date range, two chronologies
The listed span pairs dates from two different systems. The Metropolitan Museum's working dates for Sargon are ca. 2340–2285 BCE, while the alternative conventional chronology gives 2334–2279 BCE.
Neither is a date for the conquest. Both are approximate placements of a reign, and the listed endpoint 2279 belongs to the second scheme rather than to the Met's ca. 2340 start.
No evidence confines the campaign to one year, much less one day.
What the label gets wrong
"Semitic chieftain" is imprecise. Akkadian was a Semitic language, but the inscriptions present Sargon as king of Agade and king of the land, and Hideaki Maeda rejects reading the conflict as a racial confrontation between Sumerians and Akkadians.
"First empire" is a modern classification rather than an ancient title. Lugalzagesi's own rule had already spanned several Sumerian cities before Sargon defeated him.
What the inscriptions do establish is narrower and firmer: Lugalzagesi's rule ended, Ur's wall came down, and the cities that had spent generations fighting each other answered to Agade.

Date disputed. Sources disagree; the research places it at ~-2340.
What the sources leave uncertain
- The Met's ca. 2340–2285 BCE and Brinkman's 2334–2279 BCE are alternative approximate placements, not dates for two different conquests.
- The listed endpoint 2279 BCE belongs to the 2334-based chronology and should not be combined uncritically with the Met's ca. 2340 start and ca. 2285 end.
- No evidence confines the conquest to one year, much less one day.
