In 130 AD, the Roman Empire was at its height, experiencing a period of relative peace and prosperity known as the Pax Romana. This era allowed for advancements in architecture, trade, and culture across the empire, which stretched from Britain to the Middle East. During this time, the emperor was Hadrian, who is known for his efforts to consolidate and strengthen the empire's borders. He famously ordered the construction of Hadrian's Wall in Britain, marking the northern limit of Roman territory and serving as a defense against tribes from the north.
