LE-39 Armenia Prima

This province belonged to a western frontier landscape long connected with Cappadocian command. It was not the unchanged survival of Trajan’s temporary Greater Armenian annexation. Routes, garrisons, productive valleys, towns, and contacts with Armenian communities gave it both civil and strategic significance.
Christian institutions developed within this varied regional world. Justinian’s later Armenian reforms changed names, combinations, and responsibilities, so the numbered designation requires a date. The province’s enduring identity lay in its Anatolian-Armenian frontier setting rather than a fixed outline shared by every Roman province ever called Armenia Prima.
