Diocletian was responsible for ending the Crisis of the Third Century. He divided the empire, and made himself the emperor of the Eastern Empire, while Maximian reigned in the Western Empire. He eventually appointed another two "junior" emperors. By dividing power in this way, he hoped the empire would be easier to manage. He also established the largest and most bureaucratic of Roman governments.

in all honesty, it really hasn't. except that hitler killed himself.
