Theodore Rshtuni

Theodore or Theodoros Rshtuni, equated with Pasagnathes (Πασαγνάθης), the "patrikios of the Armenians" from the chronicle of Theophanes the Confessor, was an Armenian nakharar (magnate), famous for resisting the first Arab invasions of Armenia. After the previous ishkhan (prince) David Saharuni was overthrown by other nakharars in 638 or 640, Theodore Rshtuni became the leading prince of Byzantine Armenia under the same title as his predecessor, "Prince of Armenia".
