Verus's sister, on the grounds of protecting his children from a stepmother, and took a concubine instead.) Favour with Hadrian Having filled the offices of quaestor and praetor with more than usual success, he obtained the consulship in 120 having as his colleague Lucius Catilius Severus. He was next appointed by the Emperor Hadrian as one of the four proconsuls to administer Italia, his district including Etruria, where he had estates. He then greatly increased his reputation by his conduct as proconsul of Asia, probably during 134–135. He acquired much favor with Hadrian, who adopted him as his son and successor on 25 February 138, after the death of his first adopted son Lucius Aelius, on the condition that Antoninus would in turn adopt Marcus Annius Verus, the son of his wife's brother, and Lucius, son of Lucius Aelius, who afterwards became the emperors Marcus Aurelius and Lucius Verus. He also adopted (briefly) the name Imperator Titus Aelius Caesar Antoninus, in preparation for his rule. There seems to have been some opposition to Antoninus' appointment on the part of other potential claimants, among them his former consular colleague Lucius Catilius Severus, then prefect of the city. Nevertheless, Antoninus assumed power without opposition. Emperor On his accession, Antoninus' name and style became Imperator Caesar Titus Aelius Hadrianus Antoninus Augustus Pontifex Maximus. One of his first acts as Emperor was to persuade the Senate to grant divine honours to Hadrian, which they had at first refused; his efforts to persuade the Senate to grant these honours is the most likely reason given for his title of Pius (dutiful in affection; compare pietas). Two other reasons for this title are that he would support his aged father-in-law with his hand at Senate meetings, and that he had saved those men that Hadrian, during his period of ill-health, had condemned to death. Immediately after Hadrian's death, Antoninus approached Marcus and requested that his marriage arrangements be amended: Marcus' betrothal to Ceionia Fabia would be annulled, and he would be betrothed to Faustina, Antoninus' daughter, instead. Faustina's betrothal to Ceionia's brother Lucius Commodus would also have to be annulled. Marcus consented to Antoninus' proposal. Antoninus built temples, theaters, and mausoleums, promoted the arts and sciences, and bestowed honours and financial rewards upon the teachers of rhetoric and philosophy. Antoninus made few initial changes when he became emperor, leaving intact as far as possible the arrangements
