Marcus Aurelius spouse Faustina the Younger
Heir to Antoninus Pius (138–145)
Immediately after Hadrian's death, Antoninus approached Marcus and requested that his marriage arrangements be amended: Marcus's 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's proposal. He was made consul for 140 with Antoninus as his colleague, and was appointed as a seviri, one of the knights' six commanders, at the order's annual parade on 15 July 139. As the heir apparent, Marcus became princeps iuventutis, head of the equestrian order. He now took the name Marcus Aelius Aurelius Verus Caesar. Marcus would later caution himself against taking the name too seriously: 'See that you do not turn into a Caesar; do not be dipped into the purple dye – for that can happen'. At the senate's request, Marcus joined all the priestly colleges (pontifices, augures, quindecimviri sacris faciundis, septemviri epulonum, etc.); direct evidence for membership, however, is available only for the Arval Brethren.Antoninus demanded that Marcus reside in the House of Tiberius, the imperial palace on the Palatine, and take up the habits of his new station, the aulicum fastigium or 'pomp of the court', against Marcus' objections. Marcus would struggle to reconcile the life of the court with his philosophic yearnings. He told himself it was an attainable goal – 'Where life is possible, then it is possible to live the right life; life is possible in a palace, so it is possible to live the right life in a palace' – but he found it difficult nonetheless. He would criticize himself in the Meditations for 'abusing court life' in front of company.As quaestor, Marcus would have had little real administrative work to do. He would read imperial letters to the senate when Antoninus was absent and would do secretarial work for the senators. But he felt drowned in paperwork and complained to his tutor, Marcus Cornelius Fronto: 'I am so out of breath from dictating nearly thirty letters'. He was being 'fitted for ruling the state', in the words of his biographer. He was required to make a speech to the assembled senators as well, making oratorical training essential for the job.On 1 January 145, Marcus was made consul a second time. Fronto urged him in a letter to have plenty of sleep 'so that you may come into the Senate with a good colour and read your speech with a strong voice'. Marcus had complained of an illness in an earlier letter: 'As far as my strength is concerned, I am beginning to get it back; and there is no trace of the pain in my chest. But that ulcer [...] I am having treatment and taking care not to do anything that interferes with it'. Never particularly healthy or strong, Marcus was praised by Cassius Dio, writing of his later years, for behaving dutifully in spite of his various illnesses. In April 145, Marcus married Faustina, legally his sister, as had been planned since 138. Little is specifically known of the ceremony, but the biographer calls it 'noteworthy'. Coins were issued with the heads of the couple, and Antoninus, as Pontifex Maximus, would have officiated. Marcus makes no apparent reference to the marriage in his surviving letters, and only sparing references to Faustina.Marriage and children
Marcus and his cousin-wife Faustina had at least 14 children during their 30-year marriage, including two sets of twins. One son and four daughters outlived their father. Their children included:
