During the 2nd the 3rd centuries B.C. Armenia Minor continued to exist side by side with Armenia Major and developed at the same pace. Among its kings we can mention Mithradates (not to be confused with Mithradates VI Eupator, king of Pontos). King Mithradates allied himself with Pharnas I, king of Pontos, and helped him to his victory at Sinope, on the shores of the Black Sea. Mithradates wanted to conquer Cappadocia (Caesarea), but had to stand down because of Rome’s claim of this region.
Later Armenia Minor was conquered by Tigran II and Mithradates VI who divided the region between them, so that the southern part of this area (the Kharpout region) would be annexed to Armenia Major.
