|Dies imperii||September/October 268|
|Born||Marcus Aurelius Claudius|
10 May 214
Claudius (Latin: Marcus Aurelius Claudius) may have come from Illyricum in the Balkans, part of the Roman Empire. Latin historians (the authors of the Epitome de Caesaribus and the Historia Augusta) wrote that Claudius was the son of the emperor Gordian III, or was related to the emperor Probus. These claims are not true.
The Historia Augusta says that Claudius was a military tribune (Latin: tribunus militum) in the army of the emperor Decius. After that, the Historia Augusta says that Claudius was leader of a Roman legion (Latin: tribunus legionis) in the time of the emperor Valerian. Next, the Historia Augusta says that Claudius was governor of all Illyricum (Latin: dux totius Illyrici) when Gallienus was emperor. The Latin historian Aurelius Victor and the Greek historian Zonaras wrote that Claudius was a tribune (Latin: tribunus) at Ticinum (Pavia, Italy) in 268.
Claudius became emperor in September or October 268. Soon afterwards his armies overcame the Alemanni in a battle at Lake Garda on the Italian Peninsula. Claudius got the title Germanicus maximus because of this success over the Germanic peoples. For the first winter of his reign (268–269) he may have been in Rome. In 269, Claudius was Roman consul. He and his armies overcame the Goths in a battle at Naissus (Niš, Serbia). After this, Claudius got the name Gothicus maximus, because of his victory over the Goths.
In the time of the later emperor Constantine the Great, the Historia Augusta says that Claudius Gothicus had another brother with the name Crispus and a sister with the name Constantina. The Historia Augusta also says that Claudius had a daughter with the name Claudia. This is not true.
