Roman army never conquered Parthia.
The Persian Empire is the name generally given to the great Empire of Antiquity. The article as written seemed to mirror the wikipedia article and blurred distinctions between the Persian Empire and all Empires that ever existed in the land that would be considered modern day Persia, Iran. I included the Persian Empire in the Roman period as that also used the same name, at least in the Encylopedia of Military History. I'm not even sure I should have done this and I'm open to having other editors remove that section and put it in a different topic if they feel it is appropriate.
