Muṣaṣir (Assyrian cuneiform: Mu-ṣa-ṣir and variants, including Mutsatsir, Akkadian for Exit of the Serpent/Snake), in Urartian Ardini was an ancient city of Urartu, attested in Assyrian sources of the 9th and 8th centuries BC.
It was acquired by the Urartian King Ishpuini ca. 800 BC (see the Kelashin Stele). The city's tutelary deity was Ḫaldi.
Mannaea (/məˈniːə/, sometimes written as Mannea; Akkadian: Mannai, Biblical Hebrew: Minni (מנּי)) was an ancient kingdom that flourished in northwestern Iran, primarily south and southeast of Lake Urmia, during the early first millennium BCE, roughly from the 10th to the 7th century BCE. It developed into a prominent regional power along the northeastern frontier of the Neo-Assyrian Empire, situated between major neighbors like Urartu and a constellation of smaller buffer states, such as Zikirta and Musasir. The capital of Mannaea was likely at Izirtu, near modern-day Saqqez.
Mannaea played a key role in the shifting alliances between the Assyrian and Urartian empires, acting alternately as ally and adversary. Archaeological and textual evidence points to a complex society with fortified cities, regional governors, and a tributary economy. Although its exact ethno-linguistic identity remains uncertain, Assyrian sources suggest the Mannaeans spoke an unidentified language. Some scholars link it to the Hurro-Urartian family, while others, based on recent genetic evidence from Hasanlu Tepe, propose ties to Armenian or a distinct non-Indo-Iranian language.
Ishpuini (also Ishpuinis) (r. 828 – 810 BCE) was king of Urartu. He succeeded his father, Sarduri I, who moved the capital to Tushpa (Van). Ishpuini conquered the Mannaean city of Musasir, which was then made the religious center of the empire. The main temple for the war god Haldi was in Musasir. Ishpuini's kingdom was then attacked by the forces of the Assyrian King Shamshi-Adad V. Ishpuini fought and defeated Shamshi-Adad. Ishpuini was so confident in his power that he began using names meaning everlasting glory, including, "King of the land of Nairi", "Glorious King", and "King of the Universe".
Ishpuini was succeeded by his son, Menua.
The Kelashin Stele (Kurdish: کێلەشین) (also Kelishin or Keli-Shin; from Kurdish Language: Blue Stone) found in Kelashin, Iraq, bears an important Urartian-Akkadian bilingual text dating to c. 800 BC, first described by Friedrich Eduard Schulz in 1827. Part of Schulz's notes were lost when he was killed by Kurdish "bandits", and later expeditions were either prevented by weather conditions or Kurdish brigands, so that a copy (latex squeeze) of the inscription could only be made in 1951 by G. Cameron, and again in 1976 by an Italian party under heavy military protection.
The inscription describes the acquisition of the city of Musasir (Ardini) by the Urartian king Ishpuini.
