The settlement shifted the regional balance of power decisively toward [Rome](https://www.worldhistory.org/Rome/). Five eastern frontier districts: Ingilene, Sophene, Arzanene, Corduene, and Zabdicene were ceded to Roman control, while the Arsacid monarchy in Armenia was restored under Roman suzerainty and Caucasian [Iberia](https://www.worldhistory.org/disambiguation/iberia/) (Kartli) became a Roman protectorate. Nisibis became the regulated center of commercial and diplomatic exchange between the two empires, while Caucasian Albania remained within the [Sasanian Empire](https://www.worldhistory.org/Sasanian_Empire/). The treaty therefore created a frontier defined not simply by imperial borders but by kingdoms and territories positioned between Roman and Sasanian power. The settlement brought several decades of relative stability and marked a high point of Roman influence in the Caucasus, but it did not end the region's role as a contested frontier. Armenia, Iberia, Lazica, and Albania retained distinct political identities while navigating the competing influence of Rome and Sasanian [Persia](https://www.worldhistory.org/Persia/), and [trade](https://www.worldhistory.org/disambiguation/trade/), diplomacy, and religious change continued across their borders. Renewed Roman–Sasanian [warfare](https://www.worldhistory.org/warfare/) under [Shapur II](https://www.worldhistory.org/Shapur_II/) eventually overturned much of the settlement: the peace of 363 reversed major Roman gains, and the later 4th century saw Armenia divided between Roman and Sasanian spheres. #### Editorial Review This human-authored image has been reviewed by our editorial team before publication to ensure accuracy, reliability and adherence to academic standards in accordance with our [editorial policy](https://www.worldhistory.org/static/editorial-policy/). ## About the Author Simeon is a freelance visual designer and history educator, passionate about the human stories that shape the past. - [Linkedin Profile](https://www.linkedin.com/in/simeon-netchev/) ## Cite This Work ### APA Netchev, S.
