On 24 January 138, Hadrian selected Aurelius Antoninus, the husband of Marcus's aunt Faustina the Elder, as his new successor. As part of Hadrian's terms, Antoninus, in turn, adopted Marcus and Lucius Commodus, the son of Lucius Aelius. Marcus became M. Aelius Aurelius Verus, and Lucius became L. Aelius Aurelius Commodus. At Hadrian's request, Antoninus's daughter Faustina was betrothed to Lucius. Marcus reportedly greeted the news that Hadrian had become his adoptive grandfather with sadness, instead of joy. Only with reluctance did he move from his mother's house on the Caelian to Hadrian's private home.
