List of Famous people with last name Komnenos

Manuel I Komnenos, Latinized Comnenus, also called Porphyrogennetos, was a Byzantine emperor of the 12th century who reigned over a crucial turning point in the history of Byzantium and the Mediterranean. His reign saw the last flowering of the Komnenian restoration, during which the Byzantine Empire had seen a resurgence of its military and economic power, and had enjoyed a cultural revival.

Alexios I Komnenos, Latinized Alexius I Comnenus, was Byzantine emperor from 1081 to 1118. Although he was not the founder of the Komnenian dynasty, it was during his reign that the Komnenos family came to full power. Inheriting a collapsing empire and faced with constant warfare during his reign against both the Seljuq Turks in Asia Minor and the Normans in the western Balkans, Alexios was able to curb the Byzantine decline and begin the military, financial, and territorial recovery known as the Komnenian restoration. The basis for this recovery were various reforms initiated by Alexios. His appeals to Western Europe for help against the Turks were also the catalyst that likely contributed to the convoking of the Crusades.

John II Komnenos or Comnenus was Byzantine emperor from 1118 to 1143. Also known as "John the Beautiful" or "John the Good" (Kaloïōannēs), he was the eldest son of Emperor Alexios I Komnenos and Irene Doukaina and the second emperor to rule during the Komnenian restoration of the Byzantine Empire. John was a pious and dedicated monarch who was determined to undo the damage his empire had suffered following the Battle of Manzikert, half a century earlier.

Andronikos I Komnenos, usually Latinized as Andronicus I Comnenus, was Byzantine Emperor from 1183 to 1185. He was the son of Isaac Komnenos and the grandson of the emperor Alexios I.

Isaac I Komnenos or Comnenus was Byzantine Emperor from 1057 to 1059, the first reigning member of the Komnenian dynasty.

Alexios II Komnenos, Latinized Alexius II Comnenus, was Byzantine emperor from 1180 to 1183. He ascended to the throne as a minor. For the duration of his short reign, the imperial power was de facto held by regents.

Manuel Erotikos Komnenos was a Byzantine military leader under Basil II, and the first fully documented ancestor of the Komnenos dynasty. His origin and parentage is obscure. He is only mentioned in the sources as leading the defence of Nicaea in 978 against the rebel Bardas Skleros, and as an imperial envoy to him 11 years later. He had three children, late in life. The eldest, Isaac, became emperor in 1057–1059, and the youngest, John, was the progenitor of the Komnenian dynasty as the father of Alexios I Komnenos.

Isaac Komnenos or Comnenus, 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.

John Komnenos was a Byzantine aristocrat and military leader. The younger brother of Emperor Isaac I Komnenos, he served as Domestic of the Schools during Isaac's brief reign (1057–59). When Isaac I abdicated, Constantine X Doukas became emperor and John withdrew from public life until his death in 1067. Through his son Alexios I Komnenos, who became emperor in 1081, he was the progenitor of the Komnenian dynasty that ruled the Byzantine Empire from 1081 until 1185, and the Empire of Trebizond from 1204 until 1461.

Isaac Komnenos or Comnenus was the third son of Byzantine Emperor Alexios I Komnenos and Empress Irene Doukaina. He was raised to the high rank of sebastokrator by his older brother John II Komnenos in reward for his support, but they later fell out, as Isaac began to covet the throne.
