In 134 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 the expansion of trade, culture, and infrastructure across the empire, which included regions in Europe, North Africa, and the Middle East. During this time, the emperor was Hadrian, who is known for consolidating and fortifying the empire's borders. One of his significant projects was the construction of Hadrian's Wall in Britain, which marked the northern limit of Roman territory and served to protect against invasions from tribes in the north.
