Militarily he repelled an invasion by the barbarian [[Alemanni]] in southern Germany in 213, and drove back back invading [[Goths]] in 214. He reconquered [[Armenia]] and [[Mesopotamia]] from [[Parthia|Parthian]] control. While preparing to invade Parthia, he was murdered by an officer of the imperial bodyguard while he was relieving himself, either because Caracalla had recently had the officer's brother murdered or because he didn't promote him to centurion as he desired. In any case the killer was shot dead as he tried to escape by trained archers. | Militarily he repelled an invasion by the barbarian [[Alemanni]] in southern Germany in 213, and drove back back invading [[Goths]] in 214.
