What buffer zone between Rome and Persia?

The buffer zone between Rome and Persia, particularly during the conflict of the Roman Empire and the Sassanian Empire, consisted of various client states and territories that served as a buffer against direct confrontation. This region included areas like Armenia, which was often contested and served as a strategic point for both empires. The presence of these buffer states allowed for a degree of geopolitical stability, although tensions frequently flared into conflict. Ultimately, this zone played a crucial role in the power dynamics of the ancient Near East.
