-- Period: ~2334–2154 BCE @t[2334 BCE..2154 BCE]
-- Capital: Akkad (location still undiscovered)
+- Period: ~2334–2154 BCE @t[~2334 BCE..~2154 BCE]

 ## Achievements
-- First multi-ethnic empire in recorded history
-- Standardized weights and measures across Mesopotamia
-- Akkadian became the lingua franca of the ancient Near East
-- Produced significant art including the Victory Stele of Naram-Sin
+- First multi-ethnic empire in recorded history [^1]
+- Standardized weights and measures across Mesopotamia, including the Akkad-gur metric system used to measure quantities of resources such as grain and flour [^4]
+- Akkadian became the lingua franca of the ancient Near East [^1]
+- Produced significant art including the Victory Stele of Naram-Sin [^1]
+- Maintained a sophisticated imperial bureaucracy: scribal schools trained state administrators, and appointed governors reported directly to the king [^4]
 
 ## Decline
-Collapsed ~2154 BCE due to internal revolts, Gutian invasions, and possibly severe drought linked to the 4.2-kiloyear climate event [^2]. @t[~2154 BCE]
+Collapsed ~2154 BCE due to internal revolts, Gutian invasions, and severe drought linked to the 4.2-kiloyear climate event. @t[~2154 BCE] [^2] Stalagmite evidence from Gol-e-Zard Cave in northern Iran (directly downwind of Mesopotamia) identifies a major drought period beginning ~4,260 years ago (~2260 BCE) that correlates precisely with the empire's collapse, providing strong paleoclimatic corroboration for the drought hypothesis. [^3] The collapse was followed by mass migration from north to south; a 180 km wall known as the "Repeller of the Amorites" was constructed between the Tigris and Euphrates rivers to control the movement of displaced populations.

+## Recent Discoveries
+In autumn 2024, the British Museum's Girsu Project (led by Sebastian Rey, in partnership with Iraq's State Board of Antiquities and Heritage) uncovered more than 200 cuneiform tablets and 60 clay sealings at Tello in southern Iraq (ancient Girsu). @t[~2300 BCE..~2150 BCE] The tablets include scribal training texts and administrative records dating to the Akkadian period. Among the sealings is a reconstructed seal of Lugal-ushumgal, governor of Lagash, appointed directly by Naram-Sin, bearing the inscription: "Naram-Sin, the mighty, god of Akkad, king of the four quarters (of the world): Lugal-ushumgal, the scribe, governor, your servant." The finds illuminate Akkadian imperial administration and Naram-Sin's cult of personality. [^4]
