It is a bit surprising the two empires never came into direct contact. At one time they each had outposts in southwest Asia that were less than a hundred miles apart. The explanation is that the Parthians, who were key intermediaries of the Rome-China trade, successfully kept Rome and China from directly communicating with each other for hundreds of years, to Parthia's own profit.
Hello @Solomon2 ,
It is amazing that these two civilizations never a contiguous boundary, i agree with you. The Romans showed interest in expanding further into Asia as seen in their campaigns against the Parthian Empire, in fact I do remember reading the Roman Emperor Septimus Severus who had lead the Roman Army to seized the cities of Seleucia and Babylon, and sacking the great Parthian city of Ctesiphon. The Romans showed great earnest in returning to status quo ante , and never going into deep into Asia. I wonder what acted as an inhibitor for the Roman gall for conquest? Perhaps it was the issue of frontier defense in Europa? Perhaps it was the cost in maintaining the legions throughout the Empire ? For me, however, I think the Romans could have conquered Parthia , but they preferred to keep and retain her as a boundary state. Sometimes I do wonder how it would have been like had Rome expanded deep into Asia and had a contiguous boundary with the Han Dynasty.
Your insight?
