After the 5 good emperors, a time of violence and conflict followed. The emperor became whoever had the military strength to capture the title. Many emperors met violent deaths because of this. The empire was also beginning to be invaded by tribes in the north.
Many economic and military problems invasion, civil war, and plague almost caused an economic collapse. The plague affected the population and caused the military to become smaller. The empire could also not pay for any soldiers. Empire started getting soldiers from different places that weren’t loyal to the empire.
Divided the empire into four units. Emperor Diocletian reformed and divided the empire into four units, with their own ruler easier to control. After him, Constantine kept the reforms and expanded them
The eastern empire’s capital was in Constantinople; which Constantine called his “New Rome”. It became the center of the Eastern Roman Empire and one of the greatest cities in the world. After Constantine, the empire continued to be divided into West and East but it was never fully restored. The western part kept getting attacked by Germanic tribes from the North.
Already weak, the Western Empire kept getting invaded. The Huns (from Asia) came in and pushed other tribes into the Roman empire. The Visigoths moved into the Roman areas, attacked and sacked the Rome (410 AD) Other tribes like the Vandals moved all over the Roman Empire and defeated them. In 476, the emperor was killed by the German tribes (an attack was seen as the fall of the Western Roman Empire). Germanic tribes took over the Western Empire over the years.
The Western Empire was defeated, and completely destroyed. The Eastern Roman Empire (Byzantine Empire) continued in Constantinople.
