Claudius became emperor at the age of 50. He was a descendant of the Roman aristocracy. However, for years he was kept in isolation from the Roman society. Unfortunately, the associations with his name are mostly connected with his physical disabilities and marriage with Messalina, whose name has become a byword for depravity and debauchery.

For years, the emperor was engaged in historical researches related to the culture of the Etruscans. During his reign, he sought to consolidate the centralised power. Claudius is known for promoting construction. He built two of the aqueducts of Rome and one of the new ports near Ostia.
