What happened 122 AD

A shrine was erected in York to Britannia as the divine personification of Britain; coins were struck, bearing her image, identified as BRITANNIA. By the end of 122, Hadrian had concluded his visit to Britannia. He never saw the finished wall that bears his name.

Coin legends of 119–120 attest that Quintus Pompeius Falco was sent to restore order. In 122 Hadrian initiated the construction of a wall, "to separate Romans from barbarians". The idea that the wall was built in order to deal with an actual threat or its resurgence, however, is probable but nevertheless conjectural.
