The Battle of Carrhae, also known as the Battle of Callinicum, took place in 296 or 297,[1] after the invasion of Mesopotamia and Armenia by the Sasanian king Narseh. The battle took place between Carrhae (Harran) and Callinicum (al-Raqqah) and was a victory for the Sasanians. Narseh attacked with forces recruited from the Euphrates frontier. He managed to defeat his opponent by good timing.[5]
