In the Ninth Dynasty of Egypt according to Haynes, Mreyibre Khety I was of no importance in the dynasty.
Because of the contrasting opinions of scholars, Meryibre's reign is difficult to account and date with reliability; if he really was the founder of the 9th Dynasty, his reign should have conventionally begun in c. 2160 BCE, while in the second case his reign should have started about a century later.
