The Longest Wars In History Of The World
Spanning 681 years, the Roman-Persian Wars were a series of battles fought between the Roman Empire and the Persian Empire from 54 BCE to 628. Similar to Reconquista, religious differences did play a minor role, but with each empire determined to expand its borders, the dispute was largely territorial. The Mithridatic Wars marked the beginning of the conflict. Both sides experienced several victories and defeats, gaining and losing territory over the course of the 681 years. Regardless, the borders between both empires remained largely unchanged. Such a period of violence left both sides exhausted and weakened, leaving them vulnerable to the newly united Arab army. The Persian Empire crumbled quickly and completely collapsed. During the ensuing Byzantine-Arab Wars, most of the Roman Empire’s territories were lost, leaving them Anatolia, parts of the Balkans, and Italy.
