Together with Marcus Aurelius he was adopted by Antoninus Pius on 25th February 138, changing his name from Lucius Ceionius Commodus to Lucius Aelius Aurelius Commodus. In contrast to Marcus he was not made Caesar under Antoninus Pius, but on Marcus’ accession on 7th March 161 he was made joint emperor. On that occasion he again changed his name, to Imperator Caesar Lucius Aurelius Verus Augustus. In 164 (or possibly 163) he married Marcus’ eldest surviving daughter Lucilla at Ephesus. During the wars against the Parthians from 162 to 166, Verus was the nominal commander-in-chief of the Roman armies. He adopted the military titles of Armeniacus (163), Parthicus Maximus (165) and Medicus (166). A joint triumph was held on 12 October 166. He died early in 169 and was deified.
