Marcus Aurelius Carus had an extensive and successful military career under the Emperor Probus. In 282 AD, when he was inspecting troops in preparation for Probus’ campaign against the Persians, the discontent of the soldiers with their emperor boiled over, and they hailed Carus the new ruler.

              During his short reign, Carus fought the Germanic tribes and Samaritans along the Danube frontier with success. He campaigned against the Sassanid Empire and sacked their capital, but died shortly thereafter.
