While it was commonly believed that she ruled Egypt with the aid of Chancellor Bay, a recently published document by Pierre Grandet in a BIFAO 100 (2000) paper shows that Bay was executed on Siptah's orders during Year 5 of this king's reign. The document is a hieratic ostracon or inscribed potshard and contains an announcement to the workmen of Deir El-Medina of the king's actions. No immediate reason was given to show what caused Siptah to turn against "the great enemy Bay," as the ostracon states. The recto of the document reads thus: Year 5 III Shemu the 27th. On this day, the scribe of the tomb Paser came announcing 'Pharaoh, life, prosperity, and health!, has killed the great enemy Bay'. This date accords well with Bay's last known public appearance in Year 4 of Siptah. The ostracon's information was essentially a royal order for the workmen to stop all further work on Bay's tomb since the latter had now been deemed a traitor to the state. Meanwhile, Egyptian territories in Canaan seem to have become effectively independent under the overlordship of a man called Irsu. Papyrus Harris I, the main source on these events, seems to claim that Irsu and Twosret had allied themselves, leaving Irsu free to plunder and neglect the land. End of Twosret's reign Twosret's reign ended in a civil war, which is documented in the Elephantine stela of her successor Setnakhte, who became the founder of the Twentieth dynasty. It is not known if she was overthrown by Setnakhte or whether she died peacefully in her own reign; if the latter is the case, then a struggle may have ensued among various factions at court for the throne in which Setnakhte emerged victorious. However, Setnakhte and his son Ramesses III described the late 19th dynasty as a time of chaos. Setnakhte usurped the joint KV14 tomb of Seti II and Twosret but reburied Seti II in tomb KV15, while deliberately replastering and redrawing all images of Twosret in tomb KV14 with those of himself. Setnakhte's decisions here may demonstrate his dislike and presumably hatred for Twosret since he chose to reinter Seti II but not Twosret. Setnakhte's son, Ramesses III, later excluded Twosret and even Siptah of the 19th dynasty from his Medinet Habu list of Egyptian kings thereby delegitimizing them in the eyes of the citizenry. It appears more likely that Setnakhte overthrew
