Merneptah
This dynasty declined as internal fighting between the heirs of Merneptah for the throne increased. Amenmesse apparently usurped the throne from Merneptah's son and successor, Seti II, but he ruled Egypt for only 4 years. After his death, Seti regained power and destroyed most of Amenmesse's monuments. Seti was served at Court by Chancellor Bay, who was originally just a 'royal scribe' but quickly became one of the most powerful men in Egypt gaining the unprecedented privilege of constructing his own tomb in the Valley of the Kings (KV17). Both Bay and Seti's chief wife Twosret had a sinister reputation in Ancient Egyptian folklore. After Siptah's death Twosret ruled Egypt for two more years, but she proved unable to maintain her hold on power amid the conspiracies and powerplays being hatched at the royal court. She was likely ousted in a revolt led by Setnakhte, founder of the Twentieth Dynasty.
