Mamikonian
Mamikonian or Mamikonean (Old Armenian: Մամիկոնեան) was an Armenian aristocratic dynasty which dominated Armenia between the 4th and 8th centuries—through the late antique kingdom, Sasanian, Byzantine, and Arab dominations. They were the most notable noble house in early Christian Armenia after the ruling Arsacids and held the hereditary positions of sparapet (supreme commander of the army) and dayeak (royal tutor), allowing them to play the role of kingmaker for the later Armenian kings.
