Marcus Aurelius Claudius Quintillus (died 270) was a short-lived Roman emperor. He took power after the death of his brother, Emperor Claudius Gothicus, in 270 CE. After reigning for a few weeks Quintillus was overthrown by Aurelian, who had been proclaimed rival emperor by the legions he commanded. The ancient sources variously report him to have killed himself, to have fallen in battle against Aurelian, or to have been murdered by his own soldiers.
Marcus Aurelius Claudius Quintillus' exact birthplace is unknown. An Illyrian, he was likely born in Pannonia Inferior, as is indicated by his coinage.[2] Originating from a low-born family, Quintillus came to prominence with the accession of his brother Claudius Gothicus to the imperial throne in 268 CE. Quintillus was possibly made Procurator of Sardinia during his brother's reign.
