The Armenian Church, with its structure and functions, has been an inseparable part of the Armenian statehood. The study of its history, the diocesan structure, the history and status of individual dioceses, the relations between the state and the church, the church and the nobility (princes), as well as the church's interactions with foreign states in the absence of an independent state, provides us with a more accurate understanding of the processes. Indeed, the diocesan structure of the marzpanate period has been addressed in one way or another, but, in the whole, the research conducted in this area was either one-sided or incomplete.
