Rome's Northern Frontier AD 70-235

The Roman excursions north of the Tyne-Solway line, the route of Hadrian's Wall, can be roughly divided into three main periods. Firstly, Agricola advanced against the Caledonii for six campaigning seasons culminating in the decisive battle of Mons Graupius in AD 83. Secondly, the Antonine Wall was built 70 miles to the north of Hadrian's Wall along the Forth-Clyde isthmus, though it marked the northern frontier of the empire for little more than 20 years. Finally, at the beginning of the 3rd century AD L. Septimius Severus arrived to restore order along the northern frontier, briefly reoccupying and repairing sections of the Antonine Wall. This title describes the fortifications left behind by each of these three attempts to subdue Rome's northernmost frontier.
