On February 4, 211 CE, Roman Emperor Septimius Severus died and left the Roman Empire to his two sons, Caracalla and Geta, who hated each other. Caracalla and Geta hated each other so much that they would only stay in the same room with each other if they both had armed guards with them. The only person who could make them behave was their mother Julia Domna. On December 26, 211 CE, Geta died of natural causes. He went to visit his mother in her room and centurions on the orders of Caracalla stabbed him to death in her arms. Natural causes for a Roman emperor.
Their mother was understandably upset and sent the surviving son to bed without dinner. Share this post, if you were ever sent to bed without dinner... although probably not for killing your brother.
