Western Armenia (Armenian: Արևմտյան Հայաստան), also referred to as Byzantine Armenia, later Turkish Armenia, or Ottoman Armenia is a term coined following the division of Greater Armenia between Byzantine Empire (Western Armenia) and Persia (Eastern Armenia) in 387 AC. Today, it is mostly a term used for eastern parts of Turkey (formerly the Ottoman Empire) that were part of the historical homeland of Armenians.[1][2]
