Commodus had 300 concubines for his extramarital affair
One of the most corrupt and careless Roman rulers was Commodus. He never finished any of his obligations as emperor. Perennis and Cleander were put in charge by Commodus to handle state affairs and complete the majority of the Emperor's duties. At the arena, he was either competing with gladiators or watching them compete. He also frequented the brothel, where his men had constructed a harem for him to house 300 concubines.
Marcia was Commodus' preferred mistress out of the 300. He never remained devoted to his wife since, at the time, Roman polygyny was common practice. The most attractive ladies would be gathered by his warriors. He also gave orders for his soldiers to pull ladies by force into his castle. He took advantage of women to satisfy his sexual need, but he continued. A small child was taken by Commodus to his home and relatives. He gave the young lad the command to share a bare bed with him. Additionally, he had the kid formally embrace the moniker "The Boy Who Loves Commodus." There were also rumors that Commodus had his sister join his harem and had given the name of his mother to one of his concubines.
