"The Battle of Edessa took place between the armies of the Roman Empire under the command of Emperor Valerian and Sassanid forces under Shahanshah (King of the Kings) Shapur I in 260. The Roman army was defeated and captured in its entirety by the Persian forces and for the first time in Rome's military history against a foreign enemy their emperor was taken prisoner. As such, the battle is generally viewed as one of the worst disasters in Roman military history."@en . "Unknown" . "70,000" . "Unknown" . . . . . "DecisiveSassanidvictory" .
