Roman–Iranian relations

Relations between the Rome and Iranian states were established c. 96 BCE. It was in 69 BCE that the two states clashed for the first time; the political rivalry between the two empires would dominate all of Western Asia and Europe until 628. Initially commencing as arch-rivalry between the Parthians and Rome, from the 3rd to mid-7th centuries, the Byzantine Empire and its arch rival Sassanid Persia were recognized as the leading powers in the world.
