Aulus Didius Gallus was a
Roman general and politician of the 1st century AD. He was governor of
Britain between 52 and 57
AD.
Career
The career of Aulus Didius Gallus up to 51 can be partly reconstructed from an inscription from
Olympia. He was
quaestor under
Tiberius, probably in 19. He served as a
legate of the
proconsul of
Asia, as
prefect of cavalry, and as proconsul of
Sicily, although the dates of these appointments are unknown. He was
curator aquarum (superintendent of
aqueducts) from 38 to 49,
consul in 39, and a member of the
XVviri. He received
triumphal regalia as an imperial legate under
Claudius, probably in
Bosporus:
Tacitus records that he commanded forces there that were withdrawn in 49. After this he appears to have taken up another proconsular appointment, possibly in Asia or
Africa.
His later career is described by Tacitus. In 52 he was made governor of
Britain, following the death in office of
Ostorius Scapula, at a time when the situation was deteriorating as a result of a string of rebellions. The south-east was securely held, but despite the defeat of
Caratacus the previous year, the tribes of what is now
Wales, particularly the
Silures, continued to hold out.
Venutius' first insurrection against Queen
Cartimandua of the
Brigantes occurred during Didius' rule and he despatched troops under
Caesius Nasica to aid her.
Didius acted to quell the rebels rather than enlarge the empire during his rule, which lasted until AD 57. Although criticised by
Tacitus as being reactive and defensive, he was probably acting on instructions from Claudius who did not consider the benefits of further conquest in difficult terrain to be great enough to warrant the risk. Instead, Didius built roads and forts at the borders such as those at
Usk to contain the barbarians. After five years in the post, covering the last two years of the reign of
Claudius and the first three of
Nero, Didius was replaced by
Quintus Veranius.
Quintilian tells us that, after several years of campaigning for a provincial governorship, Didius complained at the province he was offered, although whether this refers to Sicily or Britain is unknown. The orator
Domitius Afer sarcastically advised him to think of his country. The next governor of Britain,
Quintus Veranius, says on his tombstone that he took the job "although he did not seek it", which has been interpreted as a barbed comment on Didius.

Aulus Didius Gallus Fabricius Veiento, who was
praetor in 62, may have been his son or grandson.
