The First Intermediate Period, described as a 'dark period' in ancient Egyptian history, spanned approximately 125 years, c. 2181–2055 BC, after the end of the Old Kingdom. It comprises the Seventh, Eighth, Ninth, Tenth, and part of the Eleventh Dynasties. The concept of a "First Intermediate Period" was coined in 1926 by Egyptologists Georg Steindorff and Henri Frankfort.

The Eleventh Dynasty of ancient Egypt is a well-attested group of rulers. Its earlier members before Pharaoh Mentuhotep II are grouped with the four preceding dynasties to form the First Intermediate Period, whereas the later members are considered part of the Middle Kingdom. They all ruled from Thebes in Upper Egypt.
