All of Armenia became a Roman province in AD 114 under Roman emperor Trajan, but Roman Armenia was soon after abandoned by the legions in 118 AD and became a vassal kingdom. Lesser Armenia, however, was generally incorporated by Trajan, together with Miletene and Cataonia into the province of Cappadocia. Lesser Armenia consisted of five districts: Orbalisene in the North; below that Aetulane (also, Ætulane); Aeretice (also Æretice); then Orsene; and finally Orbesine, the most southern. The more southern districts appended to Lesser Armenia were Miletene, so called from its capital (the modern Malatya) and the following four small districts of ancient Cataonia, namely, Aravene; Lavinianesine or Lavianesine; Cataonia, in the more restricted sense, or the country close upon Cilicia surrounded by mountains; finally, Muriane or Murianune, between Cataonia and Melitene, called likewise Bagadoania.
