Explanation:

Diocletian was emperor of Rome from November 20, 284 to May 1, 305. He became emperor at the end of what he called the third-century crisis. In this period there were 19 emperors in a period of 50 years, many only reigning for a few months. Diocletian made major changes in the rule of empire. He tried to revive the economy and divided the empire into 96 provinces which were divided into 12 diocesan regions. He also sought to revive the ancient religion of Rome, and many Christians were persecuted during his conversion.  

The most important change made by Diocletian was the beginning of the Tetrarchism, which divided the empire into four. These parts were ruled by two "Augustus", Diocletian himself and Maximinus, and two "Caesar", Galerius and Constantius Chlorus. Diocletian, like Augustus of the east, was in charge of Thracia, Asia and Egypt; Galerius in charge of the Balkans except Thracia, Maximinus as Augustus in the west controlling Italia, Hispania and Africa, and Caesar Constantius Chlorus in charge of Gaul and Britain. Each Augustus was supposed to retire after 20 years, with the two Caesars replacing them as Augustus.  But all this reform of the Roman state did nothing but generate a greater bureaucracy in the internal processes of the government, as well as a notable increase in cases of corruption, since a greater amount of power was given to a large number of people within of the government.

On 1 May 305 Dioclecian and Maximianus retired according to his plan; the first time a Roman emperor had voluntarily retired. He died in his palace in the year 313.
