 ## Decline
 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.
