What happened 211 AD

Severus is famously said to have given the advice to his sons: "Be harmonious, enrich the soldiers, scorn all others" before he died on 4 February 211. On his death, Severus was deified by the Senate and succeeded by his sons, Caracalla and Geta, who were advised by his wife Julia Domna. Severus was buried in the Mausoleum of Hadrian in Rome. His remains are now lost.

Cao Cao defeated an alliance of anti-Han rebels in modern Tongguan County, securing his control over Guanzhong.

The current stability of their joint government was only through the mediation and leadership of their mother, Julia Domna, accompanied by other senior courtiers and generals in the military. The historian Herodian asserted that the brothers decided to split the empire into two halves, but with the strong opposition of their mother, the idea was rejected, when, by the end of 211, the situation had become unbearable. Caracalla tried unsuccessfully to murder Geta during the festival of Saturnalia (17 December).

Finally, the next week, Caracalla had his mother arrange a peace meeting with his brother in his mother's apartments, thus depriving Geta of his bodyguards, and then had him murdered in her arms by centurions.
