The 17th dynasty back to the 2nd intermediate period in the ancient Egyptian history. The kings ruled in upper Egypt at this period. Some mainstream scholars have suggested that the Seventeenth dynasty of Egypt had Nubian ancestry due to the expanded presence of Nubians in Egypt during that time and the craniofacial evidence from X-ray examinations of some members of this dynasty such as Seqenenre Tao and Tetisheri who displayed strong affinities with contemporary Nubians as the Hyksos ruled the lower Egypt in the same time. The last two kings of the dynasty opposed the Hyksos rule over Egypt and initiated a war that would rid Egypt of the Hyksos kings and began a period of unified rule, the New Kingdom of Egypt.
