Арташес I
The Seleucid Empire's influence over Armenia had weakened after it was defeated by the Romans in the Battle of Magnesia in 190 BC. A Hellenistic Armenian state was thus founded in the same year by Artaxias I alongside the Armenian kingdom of Sophene led by Zariadres. Artaxias seized Yervandashat, united the Armenian Highlands at the expense of neighboring tribes and founded the new royal capital of Artaxata near the Araxes River. According to Strabo and Plutarch, Hannibal received hospitality at the Armenian court of Artaxias I. The authors add an apocryphal story of how Hannibal planned and supervised the building of Artaxata. The new city was laid on a strategic position at the juncture of trade routes that connected the Ancient Greek world with Bactria, India and the Black Sea which permitted the Armenians to prosper. Tigranes the Great saw an opportunity for expansion in the constant civil strife to the south. In 83 BC, at the invitation of one of the factions in the interminable civil wars, he entered Syria, and soon established himself as ruler of Syria—putting the Seleucid Empire virtually at an end—and ruled peacefully for 17 years. During the zenith of his rule, Tigranes the Great extended Armenia's territory outside of the Armenian Highland over parts of the Caucasus and the area that is now south-eastern Turkey, Iran, Syria and Lebanon, becoming one of the most powerful states in the Roman East.
