 His reign falls over the last six years of Warad-Sin and the first five of Rim-Sin I, the sons of Kudur-Mabuk and successive kings of Larsa, and wholly within the reign of the Babylonian monarch Apil-Sin.There are currently six extant royal inscriptions, including brick palace inscriptions, seals for his devoted servants, such as Iddin-damu, his “chief builder,” and Imgur-Sîn, his administrator, and a cone which records the construction of a storehouse for the goddess Aktuppītum of Kiritab in his honor commissioned by Nupṭuptum, the "lukur" priestess or concubine, “his beloved traveling escort, mother of his first-born.”

An inscription marks the construction of a defensive wall, called "Dūr-Suen-magir", “Suen-magir makes the foundation of his land firm,” at Dunnum, a city northeast of Nippur.Control of Nippur itself however may have shifted to Larsa, under the rule of Warad-Sîn and his father, Kudur-Mabuk, the power behind the throne, as his sixth year-name celebrates that he “had (14 copper statues brought into Nippur and) 3 thrones adorned with gold brought into the temples of Nanna, Ningal and Utu.” Larsa was to retain Nippur until year nine of Rīm-Sîn when it was lost to Damiq-ilišu.
