Claudius
Claudius (1 August 10 BC – 13 October AD 54) was a Roman emperor from AD 41 to 54.
Born to Drusus and Antonia Minor at Lugdunum in Roman Gaul, where his father was stationed as a military legate, he was the first Roman emperor to be born outside Italy.
Nonetheless, Claudius was an Italic of Sabine origins and a member of the Julio-Claudian dynasty.
Because he was afflicted with a limp and slight deafness due to sickness at a young age, his family ostracized him and excluded him from public office until his consulship, shared with his nephew Caligula in 37.
Claudius's infirmity probably saved him from the fate of many other nobles during the purges of Tiberius' and Caligula's reigns; potential enemies did not see him as a serious threat.
His survival led to his being declared emperor by the Praetorian Guard after Caligula's assassination, at which point he was the last man of his family.
Despite his lack of experience, Claudius proved to be an able and efficient administrator.
He expanded the imperial bureaucracy to include freedmen, and helped to restore the empire's finances after the excess of Caligula's reign.
He was also an ambitious builder, constructing many new roads, aqueducts, and canals across the Empire.
During his reign the Empire started its successful conquest of Britain.
Having a personal interest in law, he presided at public trials, and issued up to twenty edicts a day.
He was seen as vulnerable throughout his reign, particularly by elements of the nobility.
Claudius was constantly forced to shore up his position; this resulted in the deaths of many senators.
These events damaged his reputation among the ancient writers, though more recent historians have revised this opinion.
Many authors contend that he was murdered by his own wife.
After his death in 54 (at the age of 63), his grand-nephew, step-son, and adopted son Nero succeeded him as emperor.
His 13-year reign (slightly longer than Nero's) would not be surpassed by any successors until that of Domitian, who reigned for 15 years.
He was a descendant of the Octavii Rufi (through Gaius Octavius), Julii Caesares (through Julia Minor and Julia Antonia), and the Claudii Nerones (through Nero Claudius Drusus).
He was a step-grandson (through his father Drusus) and great-nephew (through his mother Antonia Minor) of Augustus.
He was a nephew of Tiberius through his father, Tiberius's brother.
Through his brother Germanicus, Claudius was an uncle of Caligula and a great uncle of Nero.
Through his mother Antonia Minor he was a grandson of Mark Antony and Octavia Minor.
