The new Roman emperor is named to be Claudius. This refers to Tiberius Claudius Caesar Augustus Germanicus, or Claudius I, who took over after his nephew Caligula's death in 41 CE. He was the only adult male survivor of the family at that point (Roman emperors had the habit of killing those who might be a threat to their rule), but had been viewed as a non-threat due to some physical, and possibly mental, disability. After rising to power, however, Claudius claimed that he had exaggerated his ailments to avoid assassination. He proved to have some skills as a leader, as the empire expanded during his reign, including the conquest of Britain.
