The Roman Empire was divided into east and west in 376 AD. The Roman emperor Theodosius was the first to share the empire by his sons, Honorius received the western part and Arcadius the eastern part of the empire. The Roman Empire, at that moment, had a vast surface area. In the opinion of many historians, the effort to divide the empire was the result of the desire to control and hold such a massive space more comfortable to manage.

However, after the division of the empire into east and west, there was a weakening. The new young rulers did not prove successful, leading to a weakening. The continuity of the empire's decline will continue throughout the fifth century. Poor politics, hiring troops, the economic change will eventually lead to the fall of the 476th empire. The last Roman emperor Romulus Augustus was removed from power by the barbarian warlord Odoakarus and declared himself emperor.
