Answer
Septimius Severus was the father of Geta. Severus was a notable Roman Emperor and military leader of the late 2nd century AD, remembered for expanding and consolidating the Roman Empire. Geta, on the other hand, became co-emperor alongside his brother Caracalla upon Severus' death in 211 AD, but their reign was short-lived due to Caracalla's jealousy and subsequent assassination of Geta.
