Isaac Komnenos (son of John II)

Isaac Komnenos or Comnenus (Greek: Ἰσαάκιος Κομνηνός, romanizedIsaakios Komnēnos; c. 1113 – after 1146), was the third son of Byzantine Emperor John II Komnenos by Irene of Hungary. He was bypassed by his father in favour of his younger brother Manuel I Komnenos for the succession, leading to a tense relationship between the two brothers after. He participated in the campaigns of his father and brother in Asia Minor, and was a fervent adherent of Patriarch Cosmas II of Constantinople, but little else is known about his life.

Early lifeEdit

Isaac Komnenos was born c. 1113 as the third son of John II Komnenos, emperor of the Eastern Roman Empire (r. 1118–1143), and Irene of Hungary.[1] When his oldest brother Alexios was crowned co-emperor in 1122, Isaac, along with his other brothers, was awarded the rank of sebastokrator by his father.[1] He was a tall and imposing man, but, according to the Byzantine sources—who are admittedly partial to his youngest brother and eventual successor to John II, Manuel I Komnenos (r. 1143–1180)—prone to sudden outbursts of anger and harsh punishments, so that he was not much loved.[2]

According to John Kinnamos, Isaac participated in the 1136 campaign against Armenian Cilicia, where, during the siege of Anazarbos, he counselled his father to dress the wooden siege engines with bricks, so as to thwart the defenders, who were throwing heated irons to set them on fire. This stratagem allowed the Byzantines to capture the city.[3] In 1142, while taking part in another campaign by John II in southern Anatolia, both Alexios and then the second brother, Andronikos, unexpectedly died.[1] Isaac, who had also taken part in the campaign and sent to escort Alexios' corpse along with Andronikos, accompanied the bodies of his brothers back to Constantinople.[4]

SuccessionEdit

The deaths of his older brothers left Isaac as the obvious candidate for the succession, but shortly before his death on campaign in Cilicia in April 1143, John II Komnenos designated his fourth son Manuel as his heir, bypassing Isaac.[1] The background for this nomination is unclear; contemporary Byzantine historians suggest that Manuel was more qualified, and stress that primogeniture was not decisive in Byzantine tradition.[5] The contemporary Latin historian William of Tyre, on the other hand, plainly states that the main factor was Manuel's presence with the army and his ability to lead them safely home, while Isaac was away in Constantinople.[5] According to William, the powerful megas domestikos (commander-in-chief of the army), John Axouch, John II's closest friend and aide, tried hard to persuade the emperor to nominate Isaac rather than Manuel, but once John made his decision, he steadfastly supported Manuel's claim.[5]

Isaac's presence in Constantinople, with his access to the imperial palace and its treasures, including the regalia, posed a considerable threat to Manuel's position. According to Niketas Choniates, Manuel sent Axouch in all haste to assume control in Constantinople. Indeed, Axouch managed to arrive in the capital before news of John's death arrived, seized the palace, and prevented Isaac from making his own bid for the throne by shutting him up in the Pantokrator Monastery (founded by Isaac's parents).[6][7][a] Although many in the capital thought that Isaac was better fit to rule that his younger brother, he had to resign himself to Manuel's accession.[5] After Manuel arrived in the city on 27 June, he felt himself secure enough to release his brother.[9] The relationship between the brothers remained uneasy, however, as seen in the case of Patriarch Cosmas II of Constantinople. Isaac was a fervent admirer of the patriarch, and the latter was in turn accused in 1146/47 of conspiring to raise Isaac on the throne, which contributed to Manuel's decision to depose him in February 1147.[10][11]

ConflictEdit

In 1145–1146, Isaac accompanied his brother on campaign against the Sultanate of Rum's capital, Ikonion, as one of the senior commanders of the army, along with John Axouch.[10][12] According to John Kinnamos, at the emperor's table during that campaign a heated debate occurred, with comparisons being made between the martial qualities of Manuel and his father. John Axouch offensively extolled John II to the detriment of Manuel, and was vociferously supported by Manuel's brother Isaac. Tempers became inflamed and Isaac attacked his cousin, the future emperor Andronikos, with a sword. The blow was deflected by the emperor with the aid of another kinsman, leaving Manuel himself with a minor flesh wound. Isaac was punished by being banished from Manuel's presence for a few days, while Axouch lost the right to use the imperial seals, used to seal charters conferring imperial grants.[13][b] Isaac is no longer mentioned after this, and his ultimate fate is unknown.[17]

FamilyEdit

Isaac's first wife was named Theodora, but her family or life are unknown. She probably died c. 1142/43, leaving him free to marry a second time, to Irene Diplosynadene (meaning that both her parents hailed from the Synadenos family).[18] From his first marriage Isaac had five children:[19]

By his second wife, Isaac had two daughters:

NotesEdit

  1. ^ Paul Magdalino notes that of the major historians of the period, John Kinnamos is silent about Axouch's role, and William of Tyre credits an unnamed mystikos with preventing Isaac from seizing the throne. While it is plausible that Axouch obeyed the dying wish of his friend John II and acted to prevent civil strife, his relationship with Isaac was clearly closer and more complex than that portrayed in the Byzantine accounts. Hints of this can be also seen in their common stance during the brawl in 1146 (cf. last section).[8]
  2. ^ The surviving text of Kinnamos is in poor state, and some earlier translators, including Ferdinand Chalandon and Charles M. Brand, preferred a different interpretation of the passage, placing this episode in 1154, omitting Axouch, and considering Isaac as the megas stratarches ("grand master of the army") mentioned by Kinnamos; in this emendation, furthermore, Isaac stole the imperial seals from Manuel.[14][15] This passage has since been emended differently by Paul Magdalino to the version above.[16]
