Events

Possible date of the Battle of Mons Graupius (83 or 84), in which Gnaeus Julius Agricola defeats the Caledonians.
Emperor Domitian recalls Agricola back to Rome, where he is rewarded with a triumph and the governorship of the Roman province Africa, but he declines it.
Pliny the Younger is sevir equitum Romanorum (commander of a cavalry squadron).
The construction of the Limes, a line of Roman fortifications from the Rhine to the Danube, is begun.
Through his election as consul for ten years and censor for life, Domitian openly subordinates the republican aspect of the state to the monarchical.
Domitian increases the troops' pay by one third, thus securing their loyalty.
