After the destruction of the Hurrian kingdom of Mitanni by the Hittites in the third quarter of the 14th century BC, the term Shubaru was used to refer to the remnants of the Mitanni in the upper Tigris valley. The
Middle Assyrian kings
Adad-nirari I,
Shalmaneser I, and
Tukulti-Ninurta I claimed to have defeated the Shubaru/Subarians. The Subarian peoples continued to revolt against Assyrian rule; for example, the Assyrian king
Tiglath-Pileser I () fought against the "unsubmissive Shubaru" early in his reign. Assyrian letters indicate that Shubria was under Urartian rule during the reign of
Rusa I (). It likely acquired its independence after the Urartians under Rusa were defeated by Assyria under
Sargon II in 714 BC. From the late 8th century BC, Shubria successfully preserved its independence, disregarding the interests of Urartu and Assyria. The Shubrian king frequently received refugees and fugitives from Urartu and Assyria and refused to extradite them. This included commoners escaping military or labor obligations. During the reign of
Esarhaddon of Assyria, high-ranking military and civil officials, as well as criminals, also found refuge in Shubria. This conquest is recorded in a letter from Esarhaddon to the god
Ashur, which is partially preserved on two tablets. According to the letter, the Shubrian ruler Ik-Teshub rejected Esarhaddon's demand to extradite Assyrian fugitives (possibly conspirators involved in the assassination of Esarhaddon's father
Sennacherib), Esarhaddon rebuilt the Shubrian cities, giving them Assyrian names, and populated them with people resettled from elsewhere. In 657 BC, the Urartians made an unsuccessful attempt to conquer Shubria. According to Diakonoff, it is "quite probable" that Shubria was settled by speakers of Proto-Armenian—who he believes were known as the (eastern)
Mushki and possibly also the Urumeans—from the time of Esarhaddon's conquest and deportations. Shubria likely regained its independence towards the end of the 7th century BC, like other fringe territories of the Assyrian Empire. Based on the Armenian legend about the first Armenian king
Paroyr Skayordi, some scholars have hypothesized that an Armenian-populated kingdom emerged in or near Shubria, possibly ruled by a dynasty of
Scythian origin, which allied with the
Medes to defeat the Assyrian Empire .
Suren Yeremian argues that the Armenian ruler of Shubria was recognized as king by the Median king
Cyaxares after participating in the victory over the Assyrians.
Boris Piotrovsky, who identified Arme and Shubria with each other, places this polity ruled by "Paroyr" "in the immediate vicinity of Arme, if it did not constitute it [Arme]" and also suggests that its ruler received Median recognition after participating in the victory over Assyria. Diakonoff writes that Shubria "undoubtedly played a great role in the emergence of the later Armenian state and nation," although he considers the kingdom of
Melid to be a better candidate for the nucleus of the Armenian people and kingdom. == Population ==
