Under the independent Armenian Kingdom ( 2nd century BC – 4th century AD ) , Arzanene was divided into 11 cantons with their main town-castles : Arzanene had a warm climate , and was famous for its rivers and springs , as well as its iron and lead mines . Cattle-breeding , grape cultivation and wine making were well-developed . In 298 AD , part of Arzanene was conquered by the Roman Empire , while the 387 Peace of Acilisene gave the rest of the region , except for the Aghdzn district , to the Romans as well . By 591 , all of Arzanene had been annexed by the East Roman or Byzantine Empire . In the place of destroyed Tigranakert , the Romans built a new city named Martyropolis or Nprkert . During the Arab conquest of Armenia , many Arab tribes settled in Arzanene . The Armenian population remained in the mountainous parts until the Armenian Genocide in 1915
