Amar-Sin

Amar-Sin (Akkadian: 𒀭𒀫𒀭𒂗𒍪: DAmarDSîn, "calf of Sîn", the "𒀭" being a silent honorific for "Divine"; died c. 2037 BC) initially misread as Bur-Sin (c. 2046–2037 BC middle chronology), was the third ruler of the Third Dynasty of Ur. He succeeded Shulgi, who might have been his father. His name translates to 'bull calf of the moon-god'. The name Amar-Sin was not recorded before his ascension and is a "throne name". His original name, and whether he was actually the son of Shulgi, is unknown. It has been proposed that Amar-Sin, Shu-Sin, and Ibbi-Sin were all brothers and sons of Shulgi. Alternatively, it has been suggested that Amar-Sin was a nephew of Shulgi, explaining his difficulties at the beginning and ending of his reign.
