Nikephoros Phokas Barytrachelos

Nikephoros Phokas (Νικηφόρος Φωκᾶς), surnamed Barytrachelos (Βαρυτράχηλος, "heavy-neck"; Armenian: Cṙ[a]viz, Georgian: Carvezi, "wry-neck"), was a Byzantine aristocrat and magnate, the last major member of the Phokas family to try and claim the imperial throne. He was a son of the general Bardas Phokas the Younger and great-nephew of Emperor Nikephoros II Phokas, and played an active role in his father's failed rebellion against Basil II in 987–989. After the death of his father, he sought and received Basil's pardon. Nothing further is known of him until 1022 when, along with the general Nikephoros Xiphias, he launched another rebellion. The revolt gathered widespread support, but mistrust between the two leaders led to Phokas' assassination by Xiphias on 15 August 1022. The rebellion collapsed quickly after that.

Life
He was a son of the general Bardas Phokas the Younger, and had one older brother, Leo. In spring 970, following the murder of his great-uncle Emperor Nikephoros II Phokas by John I Tzimiskes, Bardas Phokas tried to raise a rebellion against the new regime in the family's base at Cappadocia, but Tzimiskes dispatched Bardas Skleros against him. The latter was able to lure away many of Phokas' supporters, until he was forced to surrender. Bardas Phokas, along with his family, was exiled to the Aegean island of Chios.

Role in the revolts of Bardas Phokas and Bardas Skleros
In 978, after Tzimiskes' death and the rise of Basil II to the throne, Bardas Phokas was recalled to lead the imperial forces against his old rival Bardas Skleros, who had rebelled and seized much of Asia Minor. After early reverses, the loyalist forces under Phokas proved victorious in spring 979, forcing Skleros to flee to the Muslims. In 987, however, Bardas Skleros was released from Baghdad and tried to raise another revolt. He contacted Bardas Phokas for a common undertaking against Basil II, but Phokas tricked and imprisoned Skleros, before finally launching his own uprising by proclaiming himself emperor in August/September 987. It is here that Nikephoros is named for the first time in the sources, as his father sent him to David III of Tao to secure military aid and confront the loyalist general Gregory Taronites, who had landed in the Phokades' rear at Trebizond and had raised an army of Armenians in the eastern province. Nikephoros secured 1,000 Georgian soldiers from David, and defeated Taronites, but soon after, news reached him of the death of his father at the Battle of Abydos on 13 April 989, which led to the collapse of the rebellion: the Georgians returned to their country, and Nikephoros' troops dispersed to their homes. Nikephoros fled to the fortress of Tyropoion, where his mother resided and the imprisoned Bardas Skleros was held. Along with his brother Leo, he now supported Skleros' candidacy as emperor, but the latter, old and tired, preferred to give up the struggle and submit to the emperor in exchange for leniency. Leo tried to resist from Antioch, but the city's inhabitants surrendered him to Basil. Like Bardas Skleros, Nikephoros received a pardon, and was allowed to retain his privileges.

Rebellion with Nikephoros Xiphias and death
Nothing is heard of him until the summer of 1022, when he conspired with the general Nikephoros Xiphias against Basil II, who since spring had been engaged in a campaign against the Georgian king George I. The two conspirators aimed to overthrow Basil and have one of them replace him, but the issue of who would have precedence was unresolved, and would lead to the rebellion's quick downfall. Although Xiphias held the prestigious post of strategos of the Anatolic Theme, and Phokas held no office but the title of patrikios, according to the report of the contemporary Christian Arab historian Yahya of Antioch, great numbers of aristocrats flocked to him due to his family's influence, provoking Xiphias' envy.

The rebellion of the two men was particularly threatening to the emperor, as it took control over Cappadocia and threatened to cut off his rear and leave him stranded between two enemies. Indeed, the conspirators are said to have been in contact with George I for that purpose. Basil first withdrew to the safety of the fortress of Mazdat, and sent an envoy to the rebel leaders—according to Yahya this was Theophylact Dalassenos, appointed as the new governor of the Anatolic Theme—aiming to sow distrust between them. This proved an easy task, and on 15 August 1022, Xiphias arranged a meeting with Phokas, where the latter was murdered by one of Xiphias' servants. Armenian sources however report, rather dubiously, that Phokas was killed by the former king of Vaspurakan, Senekerim-Hovhannes or his son David or one of their followers. The severed head was sent to Basil, who mounted it on a stake at Mazdat and put it on public display.

Following the death of Phokas, the rebellion collapsed, and Xiphias was arrested and forced to become a monk. Released from the threat to his rear, Basil II swiftly and decisively defeated George I, and imposed his terms on him. The other supporters of the uprising were imprisoned and released in 1025, after the death of Basil II and the succession of his younger brother, Constantine VIII. In 1026, however, Constantine VIII accused the last surviving member of the once great family, Bardas Phokas (possibly a son or nephew of Nikephoros Barytrachelos) of plotting against the throne, and had him blinded.
