Although the maps presented below were drawn in the 16th century, they all feature Armenia, which hasn’t yet existed as an autonomous state. Before the 16th century, the last independent Armenian country was the Armenian Kingdom of Cilicia, which fell in 1375.
Why not “Ottoman Empire”, which would be the truth from a geographical standpoint? Was the name of Armenia still important in the international circles?
Well, considering that the Armenians have been rather active and powerful even without a sovereign state, it is quite possible that their influence spread far beyond the borders of their historical homeland.
Regardless of the background of such decision, we will probably never find it out. The only thing we know is that for some reason, European cartographers considered Armenia so significant that they even depicted it on their maps, despite the state not being independent and not existing itself!
