He was proclaimed co-emperor in his youth, before 1313, and in April 1321 he rebelled in opposition to his grandfather, Andronikos II Palaiologos. He was formally crowned co-emperor in February 1325, before ousting his grandfather outright and becoming sole emperor on 24 May 1328.

Artavasdos or Artabasdos, Latinized as Artabasdus, was a Byzantine general of Armenian descent who seized the throne from June 741 or 742 until November 743. His reign constitutes a usurpation against Constantine V, who had retained control of several themes in Asia Minor.

Symbatios, variously also Sabbatios (Σαββάτιος) or Sambates (Σαμβάτης) in some sources, was the eldest son of the Byzantine emperor Leo V the Armenian.

He reigned nominally along with his father until the latter's deposition in 820, after which he was exiled to Prote, one of the Princes Islands, as a monk.

Heraclius the Elder was a Byzantine general and the father of Byzantine emperor Heraclius. Of possible Armenian origin, Heraclius the Elder distinguished himself in the war against the Sassanid Persians in the 580s. As a subordinate general, Heraclius served under the command of Philippicus during the Battle of Solachon and possibly served under Comentiolus during the Battle of Sisarbanon. In circa 595, Heraclius the Elder is mentioned as a magister militum per Armeniam sent by Emperor Maurice to quell an Armenian rebellion led by Samuel Vahewuni and Atat Khorkhoruni. In circa 600, he was appointed as the Exarch of Africa and in 608, Heraclius the Elder rebelled with his son against the usurper Phocas. Using North Africa as a base, the younger Heraclius managed to overthrow Phocas, beginning the Heraclian dynasty, which would rule Byzantium for a century. Heraclius the Elder died soon after receiving news of his son's accession to the Byzantine throne.

He was assassinated by supporters of Michael the Amorian, one of his most trusted generals, who succeeded him on the throne.

Maurice was Byzantine emperor from 582 to 602. A prominent general, Maurice fought with success against the Sasanian Empire. After he became Emperor, he brought the war with Sasanian Persia to a victorious conclusion.

In 1072, he was blinded and sent to a monastery, where he died of his wounds.
