The wars were ended by the Arab Muslim Conquests, which led to the fall of the Sasanian Empire and huge territorial losses for the Byzantine Empire.

About Roman–Persian Wars in brief
Battles between the Parthian Empire and the Roman Republic began in 54 BC; wars began under the late Republic, and continued through the Roman and Sasanian empires. The wars were ended by the Arab Muslim Conquests, which led to the fall of the Sasanian Empire and huge territorial losses for the Byzantine Empire. Although warfare between the Romans and Persians continued over seven centuries, the frontier, aside from shifts in the north, remained largely stable. Neither side had the logistical strength or manpower to maintain such lengthy campaigns far from their borders, and thus neither could advance too far without risking stretching its frontiers too thin. Both sides did make conquests beyond the border, but in time the balance was almost always restored. The Romans and Parthians came into contact through their respective conquests of parts of the Seleucid Empire. According to James Howard-Johnston, \”from the third century BC to the early seventh century AD, the rival players were grand polities with imperial pretensions, which had been able to establish and secure stable territories transcending regional divides\”. The Roman–Persian Wars ultimately proved catastrophic for both empires, leaving them exhausted and vulnerable in the face of the sudden emergence and expansion of the Caliphate, whose forces invaded both empires only a few years after the end of the last Roman-Persian war.

Roman–Iranian Wars, also known as the Roman-Parthians Wars, were a series of conflicts between states of the Greco-Roman world and two successive Iranian empires: the ParTHian and the Sasian. The last of these wars was the Battle of Araus in 53 BC, which ended in a defeat for the Romanians under General Licinius Crassus. The battle was the worst defeat since the battle of Surena in 53BC; the Romanian defeat was catastrophic with catastrophic results; he and his son Publius were killed at the battle. Roman Empire, except for the western district of Osroene, which became a Roman dependency, became a dependency of Parthia in the 2nd century BC. Roman Republic, followed by Eastern Roman empire later. Roman Sasanians, were succeeded by Byzantine Empire, which was later succeeded by the Roman Empire. Roman Roman Wars, or Roman-Iranian wars, ended in 7th century AD. Roman and Sasanians were enemies for most of the time; they fought each other over territory in the Levant, the Caucasus, Egypt, and the rest of North Africa. Roman Romans were defeated by the Sasanias in the Battle of Araus, but the Romans were able to regain control of Mesopotamia in the 1st century BC. The Roman Roman Wars ended in 64 BC when Pompey conquered Syria, extinguishing their state and advancing the Roman eastern frontier to the Euphrates.
