How did diocletian try to stop romes decline?

Diocletian sought to stop Rome's decline by instituting a series of reforms that aimed to stabilize the empire's economy and administration. He divided the empire into smaller, manageable provinces and established the Tetrarchy, which created four co-emperors to better govern and respond to local issues. Additionally, he enacted price controls and wage regulations to combat inflation and improve economic stability. These reforms helped temporarily restore order but did not ultimately prevent the empire's long-term decline.
