Armenians
Under Tigranes the Great, a member of this dynasty, during his reign, Kingdom of Armenia stretched from the Caspian Sea to the Mediterranean and the Kingdom of Armenia was called the "Armenian empire" during her reign. At one time, the domains of Tigranes the Great stretched from the shores of the Caspian Sea to the Mediterranean, from Mesopotamia up to the Pontic Alps. The vast empire, formed of a varied mixture of diverse tribes, with their own dialects and cultures, could hardly be turned over- night into a cohesive and durable political structure. Inner disunity aided the designs of the Romans, who launched a series of onslaughts on the Armenian dynast, beginning with the invasion by Lucullus in 69-68 B.C, and culminating in the campaigns of Pompey in Armenia, Iberia and Colchis in 66-65 B.C. The downfall of Tigranes the Great was precipitated by the flight of his son, Tigranes the Younger, to the court of the Parthian king Phraates III, who supplied him with an army with which to invade Armenia, and join forces with the victorious Romans.
