In preparation for a praetorship, Vespasian needed two periods of service in the minor magistracies, one military and the other public. Vespasian served in the military in Thrace for about 3 years. On his return to Rome in about AD 30, he obtained a post in the vigintivirate, the minor magistracies, most probably in one of the posts in charge of street cleaning.[9] His early performance was so unsuccessful that Emperor Caligula reportedly stuffed handfuls of muck down his toga to correct the uncleaned Roman streets, formally his responsibility.[7]
During the period of the ascendancy of Sejanus, there is no record of Vespasian’s significant activity in political events. After completion of a term in the vigintivirate, Vespasian was entitled to stand for election as quaestor; a senatorial office. But his lack of political or family influence meant that Vespasian served as quaestor in one of the provincial posts in Crete, rather than as assistant to important men in Rome.[9]
Next he needed to gain a praetorship, carrying the Imperium, but non-patricians and the less well-connected had to serve in at least one intermediary post as an aedile or tribune. Vespasian failed at his first attempt to gain an aedileship but was successful in his second attempt, becoming an aedile in 38. Despite his lack of significant family connections or success in office, he achieved praetorship in either 39 or 40, at the youngest age permitted (30), during a period of political upheaval in the organisation of elections. His longstanding relationship with freedwoman Antonia Caenis, confidential secretary to the Emperor’s grandmother and part of the circle of courtiers and servants around the Emperor, may have contributed to his success.[9]
Invasion of Britannia (43)[edit]
Upon the accession of Claudius as emperor in 41, Vespasian was appointed legate of Legio II Augusta, stationed in Germania, thanks to the influence of the Imperial freedman Narcissus. In 43, Vespasian and the II Augusta participated in the Roman invasion of Britain, and he distinguished himself under the overall command of Aulus Plautius. After participating in crucial early battles on the rivers Medway and Thames, he was sent to reduce the south west, penetrating through the modern counties of Hampshire, Wiltshire, Dorset, Somerset, Devon and Cornwall with the probable objectives of securing the south coast ports and harbours along with the tin mines of Cornwall and the silver and lead mines of Somerset.
Vespasian marched from Noviomagus Reginorum (Chichester) to subdue the hostile Durotriges and Dumnonii tribes,[10] captured twenty oppida (towns, or more probably hill forts, including Hod Hill and Maiden Castle in Dorset). He also invaded Vectis (now the Isle of Wight), finally setting up a fortress and legionary headquarters at Isca Dumnoniorum (Exeter). During this time he injured himself and had not fully recovered until he went to Egypt. These successes earned him triumphal regalia (ornamenta triumphalia) on his return to Rome.
