After ruling over Babylonia for three years and eight months, Neriglissar died. His son Lâbâši-Marduk, whose name means "O Marduk, may I not come to shame" (Akk. Lā-abâš-Marduk), ascended the throne.[[14]] The royal court did not approve of him becoming king since he was still a young child and inexperienced and, therefore, had him removed and killed shortly after he assumed power.[[15]] Nabonidus, who was placed on the throne in his stead, states that Lâbâši-Marduk "was untutored in proper behavior (and) ascended the royal throne against the will of the gods"; this biased statement about the impiety of his immediate predecessor, undoubtedly, sought to legitimize Nabonidus' own claim to the throne.[[16]] Lâbâši-Marduk was not in power long enough for him to accomplish anything and, therefore, it does not come as any surprise that no royal inscription recording his deeds has yet come to light.
14 For studies on his reign, see, for example, Da Riva, GMTR 4 p. 16; and Röllig, RLA 6/5–6 (1983) p. 409.
15 Da Riva, GMTR 4 p. 16. The classical authors Josephus and Berossos erroneously state that Lâbâši-Marduk was king for nine months. Economic and administrative records from Uruk and Sippar support the Uruk King List's statement that he ruled over Babylonia for about three months. His short reign is omitted in the Ptolemaic Canon. Nabonidus' personal involvement in Lâbâši-Marduk's assassination is assumed, although there is no direct evidence to prove it with certainty.
