 It is safer to recognize that we simply don't know the precise date on which the Whm Mswt was inaugurated.The exact nature of the Whm Mswt is still unknown.It is often believed to mark a final waning of the power of the centralised monarchy, with Ramesses XI still nominally pharaoh, but with Herihor as High Priest of Amun in Thebes and Smendes in Tanis ruling respectively Upper and Lower Egypt.
