Diocletian: A Military and Administrative Biography in 10 Minutes

Introduction

Introduction

Diocletian was a Roman emperor who ruled from 284 to 305 AD during a time of great political and economic turmoil in the Roman Empire. His reign is often considered a crucial period in Roman history, as he implemented significant reforms that helped stabilize the empire and laid the groundwork for the Byzantine Empire.

One of Diocletian's most notable achievements was the division of the Roman Empire into the Eastern and Western halves, with each half having its own co-emperor. This division helped to decentralize power and make the empire easier to govern.
