Started in 142 C.E, the new wall would not be finished until 154 C.E. The Caledonian tribe, immediately to the north, proved to be a constant thorn in the side of those constructing the wall, and their recalcitrance would not be ended by its completion. The garrisons in the forts to its north, as well as those manning the wall, would be under constant pressure from this adversarial tribe.
After the death of Antoninus in 161 C.E. his successors (Marcus Aurelius and Lucius Verus) ordered the abandonment of the Antonine Wall. The Roman legions fell back to Hadrian’s Wall, leaving the previously conquered tribes to act as a buffer against the Caledonians. Though additional forays in 197 would lead to a brief reoccupation of the wall, Hadrian’s Wall would remain as the northern border of the Roman Empire until sometime around the turn of the 5th century.
