In 498 in the settlement named Aghuen (in present-day Mardakert region of Nagorno-Karabakh), an Albanian church assembly was held, in the presence of the nobility and princes ("azgapetk") of Artsakh and the king Vachagan the Pious, to adopt the "Constitution of Aghven", which would arrange relations between the nobility (landlords), clergy and village people.
