Peace of Nisibis

The Peace Treaty of Nisibis was concluded between the Roman and Sassanid Persian empires at Nisibis (now Nusaybin, Turkey) in 299. It ended the Roman–Sassanid war and enforced the Roman military exploits during the conflict. Rome was acknowledged its suzerain rights over Armenia and Georgian Kingdom of Iberia and received a part of Upper Mesopotamia that extended even beyond the Tigris -including the cities of Tigranokert, Saird, Martyropolis, Balalesa, Moxos, Daudia, and Arzan. Peace was thus assured for some decades until its collapse with the resurgence of Shapur II in the 330s.
