Ramesses XI (also written Ramses and Rameses) reigned from 1107 BC to 1078 BC or 1077 BC and was the tenth and final king of the Twentieth dynasty of Egypt. He ruled Egypt for at least 29 years although some Egyptologists think he could have ruled for as long as 30 years. The latter figure would be up to 2 years beyond this king's highest known date of Year 10 of the Whm-Mswt era or Year 28 of his reign. One scholar, Ad Thijs, has even suggested that Ramesses XI reigned as long as 33 years—such is the degree of uncertainty surrounding the end of his long reign. He was, perhaps, the son of Ramesses X by Queen Tyti who was a King's Mother. He married both Baketwernel a King's Sister, and Tentamun, the daughter of Nebseny, with whom he fathered Henuttawy--the future wife of the high priest Pinedjem I.
