Persia (various factions) and the Roman Empire, even pre the east-west split, had numerous wars.

Buwaya, as usual, you're full of shit. There were conflicts and skirmishes, but there was never a major war between Persia and the Roman Empire from the beginning of the Roman Empire (27 BC) to the end of the Roman Empire (286 AD).

You won't be able to provide the dates of that war because it never happened.

The Roman empire lasted until the mid fifth century. So if you got that part wrong I have to question your whole premise.

Trajan took Ctesiphon in 114 or 115. After defeating the Persian (Parthian) armies in Armenia, the Romans marched through Mesopotamia and took the Parthian capital.

Look it up. There are more BTW.

Some other minor wars

- the Romans again took (and sacked) Ctesiphon in 165 or 166

- And Septimus Severus did so again in @ 198.

Among other wars, I’m just counting those where the Romans got all the way to the Parthian capital.

Armenia seems to have worked more as a generator of pretexts for wars than a peacekeeping buffer.
