Komnenos

The House of Komnenos ( Komnenoi; , , ), Latinized as Comnenus ( Comneni), was a Byzantine Greek noble family who ruled the Byzantine Empire in the 11th and 12th centuries. The first reigning member, Isaac I Komnenos, ruled from 1057 to 1059. The family returned to power under Alexios I Komnenos in 1081 who established their rule for the following 104 years until it ended with Andronikos I Komnenos in 1185. In the 13th century, they founded the Empire of Trebizond, a Byzantine rump state which they ruled from 1204 to 1461. At that time, they were commonly referred to as Grand Komnenoi (, ), a style that was officially adopted and used by George Komnenos and his successors. Through intermarriages with other noble families, notably the Doukas, Angelos, and Palaiologos, the Komnenos name appears among most of the major noble houses of the late Byzantine world.

==Origins== The 11th-century Byzantine historian Michael Psellos reported that the Komnenos family originated from the village of Komne, in southern Thrace—usually identified with the "Fields of Komnene" () near Adrianople mentioned in the 14th century by John Kantakouzenos, or further south at Komniana () according to Varzos—a view commonly accepted by modern scholarship. The first known member of the family, Manuel Erotikos Komnenos, acquired extensive estates at Kastamon in Paphlagonia, which became the stronghold of the family in the 11th century. The family thereby quickly became associated with the powerful and prestigious military aristocracy () of Asia Minor, so that despite coming from Thrace it came to be considered "eastern". Aside from deriving legitimacy as rulers from familial links to the prominent Doukai (emperors Constantine X and Michael VII in particular), they also had a tradition linking them to Claudius Gothicus, the supposed grandfather of Constantine the Great. Many classical monuments dedicated to Claudius stood in the vicinity of Kastra Komnenon, which according to historian Maximilian C. G. Lau may have increased his appeal in the eyes of the Komnenoi.
