The Roman empire was located in Europe and Africa
An empire is a sovereign state functioning as an aggregate of nations or people that are ruled over by an emperor or another kind of monarch. The territory and population of an empire is commonly of greater extent than the one of a kingdom.[1]
An empire can be made solely of contiguous territories, such as the Austro-Hungarian Empire or the Russian Empire, or of territories far remote from the homeland, such as a colonial empire. Aside from the more formal usage, the word empire can also refer colloquially to a large-scale business enterprise (e.g. a transnational corporation), a political organisation controlled by a single individual (a political boss), or a group (political bosses).[2] The word empire is associated with such other words as imperialism, colonialism, and globalization. Empire is often used to describe a displeasure to overpowering situations.[3]
Answer:
Ancient Rome had a large influence on the modern world. Though it has been thousands of years since the Roman Empire flourished, we can still see evidence of it in our art, architecture, technology, literature, language, and law.
Hadrian focused his reign in establishing frontiers of the roman empire that were easy to defend. In the ones that were harder to defend, he focused on building several kind of fortifications like pits, embankments, watchtowers, and palisades.
The most famous one was a wall in the province of Britain, nowadays known as "The Hadrian's wall", which prevented northern invasions from barbarians.
