Commodus bankrupted Rome
For Commodus, progress and peace were nothing. He only desired to lead a lavish life within the castle. Commodus would squander the resources of the Empire on his personal preferences. Even if murder isn't a common pastime, it has harmed the economy. Commodus billed the state a million sesterces each time he appeared in the gladiatorial arena. As a result, Commodus had to spend a lot of money on his pleasure, depleting the country's resources. His obsession with murder took lives, but it also contributed to the utter collapse of the Roman economy.
The Roman Empire's economic decline wasn't just a result of Commodus' amusement. He had caused a domino effect by devaluing the Roman money. Roman money devaluation was not a novel idea. Emperor Nero had done it before Commodus. However, under Commodus' rule, there was a significantly greater degree of monetary devaluation. Devaluing money was a far more direct procedure in Roman times than it is now. Commodus decreased the quantity of gold and silver in Roman coins, making them lighter and thus less valuable. Commodus depreciated Roman coinage more than any other emperor after him. The nation was devastated by it even throughout his lifetime. Commodus, according to one Roman who lived during his rule, turned Rome "from a realm of gold to one of iron and rust."
