Lucius Aelius Caesar was the father of Emperor Lucius Verus. In 136, he was adopted by the reigning emperor Hadrian and named heir to the throne. He died before Hadrian and thus never became emperor. After Lucius' death, he was replaced by Antoninus Pius, who succeeded Hadrian the same year.

Lucius Aurelius Verus was Roman emperor from 161 until his death in 169, alongside his adoptive brother Marcus Aurelius. 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 more than one emperor simultaneously, an increasingly common occurrence in the later history of the Empire.
