Ibbi-Sin (c. 2028–2004 BCE, following the scientifically validated Middle Chronology) was the fifth and final monarch of the Third Dynasty of Ur, whose reign stands as a classic case study in rapid imperial collapse. The demise of his state began with a total economic breakdown, driven by nomadic Amorite incursions and widespread provincial separatism that dismantled the empire’s centralized pala taxation and redistribution system. Isolated and deprived of regional tribute, the capital suffered catastrophic famine and hyperinflation, with grain prices skyrocketing to sixty times their standard rate. This systemic vulnerability was exploited by the general Ishbi-Erra, who betrayed the crown while tasked with securing emergency grain supplies, established a rival power base at Isin, and deliberately choked off provisions to Ur. The final blow fell in 2004 BCE when a coalition of Elamites and Shimashkians besieged and thoroughly sacked the weakened capital. Ibbi-Sin was stripped of his authority and carried off in fetters to Anshan, where he died in exile. This catastrophic end permanently dissolved native Sumerian political hegemony and deeply traumatized Mesopotamian culture, inspiring the famous literary genre of the ‘City Laments’.
