Azgapet is a leader of a tribe or clan in ancient and medieval Armenia, similar to chieftain. The term originates from the words azg (Armenian: ազգ), which means extended family or clan, and pet, which means chief. [1] The term azgapet had been used in addition to other similar terms for tribal collectivities, such as tanuter (Armenian: տանուտեր) and nahapet (Armenian: նահապետ). Patriarch Hayk, the legendary and eponymous progenitor of the Armenian people, is sometimes referred to as azgapet.[2] One prominent medieval work which mentions Armenian azgapets is The History of the Province of Aghvank by Movses Kaghankatvatsi,[3] which mentions several dignitaries, including azgapets, who signed the Constitution of Aghven, a 5th-century legal document commissioned by King Vachagan II the Pious of Aghvank. One family with origins in the village of Syghnakh in Artsakh claims descent from azgapet Marut, a chieftain from Varanda Valley and a consignee of the Constitution.[4]
