Quizplus · Accepted Answer

All of these factors contributed to the Roman army falling out of control in the third century. The debasement of coinage led to inflation, making soldiers' pay worthless. This economic instability, combined with political ambitions, encouraged soldiers to overthrow emperors in hopes of receiving a donative from the new emperor. Additionally, the practice of declaring their commanders as emperors and marching on Rome to influence the Senate's decisions further destabilized the empire and undermined central authority.
