Theophylact Dalassenos

Theophylact Dalassenos (Greek: Θεοφύλακτος Δαλασσηνός; born before ca. 990 – after 1039) was a Byzantine aristocrat who occupied a series of senior military positions in the 11th century.

Theophylact was the son of Damian Dalassenos, the first attested member of the distinguished Dalassenos aristocratic clan. He first appears in 998, when he accompanied his father, then holding the post of doux of Antioch, in battle against the Fatimids. In the resulting Battle of Apamea Damian was killed and Theophylact, along with his brother Constantine, were taken prisoner. They were then sold on to the Fatimid general Jaysh al-Samsama for 6,000 gold dinars, spending the next ten years in captivity in the Fatimid capital of Cairo.

Following his release he continued his military career, but his life is obscure until 1021/22, by which time, according to Yahya of Antioch, he held the rank of protospatharios and droungarios (most likely the post of droungarios tes viglas). In August 1022, Emperor Basil II (reigned 976–1025) appointed him strategos (military governor) of the Anatolic Theme and gave him money to raise troops, with the task of suppressing the rebellion of Nikephoros Xiphias and Nikephoros Phokas Barytrachelos. In the end, the two rebels fell out and Xiphias had Phokas assassinated; as the rebellion collapsed, Dalassenos took Xiphias prisoner and brought him for trial to Constantinople.
