Manishtushu, whose name translates to "Who is with him?", was a prominent figure in the ancient Akkadian Empire, serving as its third king. He reigned for a period of fifteen years, approximately from two thousand two hundred seventy BC until his death around two thousand two hundred fifty-five BC. As the son of the illustrious Sargon the Great, the founder of the Akkadian Empire, Manishtushu inherited a legacy of power and influence.
Upon his passing, Manishtushu was succeeded by his son, Naram-Sin, who honored his father's memory by deifying him posthumously. This act of reverence is evidenced by a cylinder seal, likely from the reign of Naram-Sin or later, which refers to Manishtushu as the divine figure, indicating the lasting impact of his rule.
Further texts from the Ur III period reveal that offerings were made to the deified Manishtushu, showcasing the continued veneration of his legacy. The name of a town associated with him, spelled as ᵈMa-an-iš-ti₂-su, is mentioned in these texts, highlighting the existence of a temple dedicated to him. This temple, known during the Sargonic period as Ma-an-iš-t[i-s]uki, served as a significant site of worship and remembrance.
