Lucius Verus (130 - 169). Lucius Verus was the co-emperor of Rome with his adoptive brother Marcus Aurelius from 161 until his own death in 169. He was a member of the Nerva-Antonine dynasty. Verus' succession together with Marcus Aurelius marked the first time that the Roman Empire was ruled by multiple emperors, an increasingly common occurrence in the later history of the Empire. The eldest son of Lucius Aelius Caesar, first adopted son and heir to Hadrian, Verus was born and educated in Rome where he held several political offices prior to taking the throne. After his biological father's death in 138, he was adopted by Antoninus Pius, who was himself adopted by Hadrian. Hadrian died later that year, and Antoninus Pius succeeded to the throne. Antoninus Pius ruled until 161 and was succeeded by Lucius Verus and Marcus Aurelius. The majority of Verus's reign was occupied by his direction of the war with Parthia which ended in Roman victory and some territorial gains. After initial involvement in the Marcomannic Wars, he fell ill and died in 169. He was deified by the Roman Senate as the Divine Verus. Born Lucius Ceionius Commodus on 15 December 130, Verus was the first-born son of Avidia Plautia and Lucius Aelius Caesar, the first adopted son and heir of Emperor Hadrian. He was born and raised in Rome. Verus had another brother, Gaius Avidius Ceionius Commodus, and two sisters, Ceionia Fabia and Ceionia Plautia. His maternal grandparents were the senator Gaius Avidius Nigrinus and the unattested noblewoman Ignota Plautia. Although Hadrian was his adoptive paternal grandfather, his biological paternal grandparents were the consul Lucius Ceionius Commodus and either Aelia or Fundania Plautia. When his father died in early 138, Hadrian chose Antoninus Pius as his successor. Antoninus was adopted by Hadrian on the condition that Verus and Hadrian's great-nephew Marcus Aurelius be adopted by Antoninus as his sons and heirs. By this scheme, Verus, who was already Hadrian's adoptive grandson through his natural father, remained as such through his new father, Antoninus. The adoption of Marcus Aurelius was probably a suggestion of Antoninus himself, since Marcus was the nephew of Antoninus' wife. 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. As a prince and future emperor, Verus received careful education from the famous grammaticus Marcus Cornelius Fronto. He was reported to have been an excellent student, fond of writing poetry and delivering speeches. Verus started his political career as a quaestor in 153, became consul in 154, and in 161 was consul again with Marcus Aurelius as his senior partner. Antoninus died on 7 March 161, and was succeeded by Marcus Aurelius. Marcus Aurelius bore deep affection for Antoninus, as evidenced by the first book of Meditations. Although the senate planned to confirm Marcus alone, he refused to take office unless Lucius received equal powers. The senate accepted, granting Lucius the imperium, the tribunician power, and the name Augustus. Marcus became, in official titulature, Imperator Caesar Marcus Aurelius Antoninus Augustus; Lucius, forgoing his name Commodus and taking Marcus's family name, Verus, became Imperator Caesar Lucius Aurelius Verus Augustus. It was the first time that Rome was ruled by two emperors. In spite of their nominal equality, Marcus held more auctoritas, or authority, than Verus. He had been consul once more than Lucius, he had shared in Pius' administration, and he alone was Pontifex maximus. It would have been clear to the public which emperor was the more senior. As the biographer wrote, Verus obeyed Marcus.as a lieutenant obeys a proconsul or a governor obeys the emperor. Immediately after their senate confirmation, the emperors proceeded to the Castra Praetoria, the camp of the praetorian guard. Lucius addressed the assembled troops, which then acclaimed the pair as imperatores. Then, like every new emperor since Claudius, Lucius promised the troops a special donative. This donative, however, was twice the size of those past: 20,000 sesterces per capita, more to officers. In return for this bounty, equivalent to several years' pay, the troops swore an oath to protect the emperors. The ceremony was perhaps not entirely necessary, given that Marcus' accession had been peaceful and unopposed, but it was good insurance against later military troubles.
