Vespasian, as a reward for its having taken his part, gave the town part of the territory of Capua, and installed more colonists there - whence it took the title Colonia Flavia, which it retained till the end of the empire.
It was not constructed before the reign of Vespasian, for inscriptions record that it was built by the Colonia Flavia.
In the 5th century there were five provinces, Britannia Prima and Secunda, Flavia and Maxima Caesariensis and (for a while) Valentia, ruled by praesides and consulares under a vicarius, but the only thing known of them is that Britannia Prima included Cirencester.
Having distinguished himself by his military ability and his able and gentle rule of Dalmatia, he was, on the 1 st of March 293, adopted and appointed Caesar by Maximian, whose step-daughter, Flavia Maximiana Theodora, he had married in 289 after renouncing his wife Helena (the mother of Constantine).
After having served with the army in Thrace and been quaestor in Crete and Cyrene, Vespasian rose to be aedile and praetor, having meanwhile married Flavia Domitilla, the daughter of a Roman knight, by whom he had two sons, Titus and Domitian, afterwards emperors.
