Step-by-step explanation:
Empire of the Romans From 27 BC to 476 AD, the post-republican period of ancient Rome was ruled by emperors in North America, Europe, and West Asia. During this period, for the first two centuries, Rome saw a period of stability that reached its largest territorial spread. During this period the absolute rule of monarchy has been used. However, after the Palmyrene empire broke up and Gallic empire broke out of Rome and a small empire ruled the empire, the existence of the empire was threatened.
However, the empire was reunited under Aurelian, establishing two imperial courts. Finally, the Western Roman Empire would collapse and the Eastern Roman Empire would survive.
The Roman Republic was ruled by the constitutional style of republic governance between 509BC and 27BC. The Roman Kingdom preceded the regime and the Roman Empire succeeded it. In contrast, from 27 BC to 476 AD, the Roman Empire ruled and used the absolute style of monarchy governance. The Roman Republic was preceded and the West and East Roman Empire were replaced.
