Diocletian was a Roman Emperor who ruled from 284 to 305 AD and is best known for his significant reforms that transformed the structure of the Roman Empire. He established the Tetrarchy, dividing the empire into four regions governed by two senior emperors (Augusti) and two junior emperors (Caesares) to improve administrative efficiency and stabilize the empire amid crisis. Diocletian also initiated the last and most severe persecution of Christians, aiming to reinforce traditional Roman religious practices. After abdicating in 305 AD, he retired to his palace in Split (modern-day Croatia), where he spent his remaining years in relative obscurity.
