Domitian was the younger brother of Titus and son of Vespasian, and the last member of the Flavian dynasty. As emperor, Domitian strengthened the economy by revaluing the Roman coinage, expanded the border defenses of the empire, and initiated a massive building program to restore the damaged city of Rome. Significant wars were fought in Britain, where his general Agricola attempted to conquer Caledonia (Scotland). However, his authoritarian rule put him at sharp odds with the Senate, whose powers he drastically curtailed. Ultimately, he was assassinated by court officials and his memory condemned to oblivion by the Roman Senate.
