During his reign, Claudius revived the rumor that his father Drusus was actually the illegitimate son of Augustus, to give the appearance that Augustus was Claudius' paternal grandfather.
In 9 BC, his father Drusus unexpectedly died on campaign in Germania, possibly from illness.
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.
Despite his lack of experience, Claudius proved to be an able and efficient administrator.
