Wikipedia names at least two "battles of Bagrevand",
- In 371 between Persia and allied Roman-Armenian forces
- In 775 between the Abbasid Caliphate and rebelling Armenian princes
both occuring in the "plains of Bagrevand", but it did not name the modern day location of these battles. "Bagrevand" itself has a Wikipedia entry, but it is only described as "a region of the old kingdom Greater Armenia" without mentioning any specific location. Where approximately is the historical plains of Bagrevand?
