What were Marcus aurelius's downfalls?

Answer 1

Marcus Aurelius was a successful emperor. His generals won a war with Persia (161-166). He fought the Marcomannic War (166-173) against Germanic peoples who had crossed the river Danube. During that campaign he fell ill and there were rumours that he had died. A rebellion broke out in most of the eastern part of the empire. However, when he became clear that he was not dead, the rebellion ended and the leader of the rebellion was killed by the troops. During a further military campaign in the north (174-180) he fell ill again and died.
