The Kourkouas family or Curcuas (Medieval Greek: Κουρκούας, from Armenian: Գուրգեն, Gurgen) was, allegedly, one of the many nakharar families from Armenia that migrated to the Byzantine Empire during the period of Arab rule over Armenia (7th–9th centuries) although the latter is mostly speculative.^[1] They rose to prominence as part of the Anatolian military aristocracy in the 10th century, providing several high-ranking generals and an emperor. They intermarried extensively with the aristocratic families of Phokas and Skleros. In the 11th and 12th centuries, they shifted to the civilian bureaucracy.
