Gagik Bagratouni was a Vaspurakaner general who led a contingent of his countrymen alongside Avtokrator Mavrikios Gavras during the Maragha campaign and the whole of the War Against the Yezda. He had a commanding presence, as Marcus Scaurus of the Ronams noted when Bagratouni reviewed the Videssian army outside the town of Amorion in the west of Videssos; the Roman likened Bagratouni to a lion and compared him to Julius Caesar and the Roman general's resemblance to an eagle.
