His mother, Vespasia Polla, also belonged to the equestrian order in society, with her father rising to the rank of prefect of the camp and her brother becoming a Senator. He was educated in the countryside, in Cosa, near what is today Ansedonia, Italy, under the guidance of his paternal grandmother, so much so that even when he became emperor, he often returned to the places of his childhood, having left the former villa exactly as it had been. Early in his life he was somewhat overshadowed by his older brother, Titus Flavius Sabinus, who had entered public life and pursued the cursus honorum, holding an important military command in the Danube. Vespasian served in the army as a military tribune in Thrace in 36 AD. He was elected quaestor the following year and then served in Creta et Cyrenaica. He rose through the ranks of Roman public office, being elected aedile on his second attempt in 39 and praetor on his first attempt in 40, taking the opportunity to ingratiate himself with the Emperor Caligula. Military and political career Early career 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 Thracia for about three years. On his return to Rome in about 30 AD, he obtained a post in the vigintivirate, the minor magistracies, most probably in one of the posts in charge of street cleaning. 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. 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. 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
