Gaius Caesar
Under the threat of an impending war between the two powers, Gaius Caesar and Phraataces worked out a rough compromise between the two powers in 1 AD. According to the agreement, Parthia undertook to withdraw its forces from Armenia, and to recognize a "de facto" Roman protectorate over the country. Nonetheless, Roman-Parthian rivalry over control and influence in Armenia continued unabated for the next several decades.
