Why was the Hadrian wall built for and did it work?

Answer 1

The Hadrian's Wall was built by the Romans around AD 122 to defend the Roman frontier in Britain from invasions by the tribes in what is now Scotland and to control smuggling and Immigration. It served as a physical barrier and a symbol of Roman power, enabling the Romans to manage trade and troop movements effectively. While it did provide some level of defense and control, it was not wholly effective in preventing incursions, as tribes often bypassed or breached it. Ultimately, it marked the northern limit of Roman Britain but could not completely stop conflict in the region.
