text: The Eleventh Dynasty of ancient Egypt (notated Dynasty XI; ) 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.
  Characteristics
  The relative chronology of the 11th Dynasty is well established by contemporary attestations and, except for count Intef and Mentuhotep IV, by the Turin canon.
  Manetho's statement that the 11th Dynasty consisted of 16 kings, who reigned for 43 years is contradicted by contemporary inscriptions and the evidence of the Turin King List, whose combined testimony establishes that this kingdom consisted of seven kings who ruled for a total of 143 years. However, his testimony that this dynasty was based at Thebes is verified by the contemporary evidence. It was during this dynasty that all of ancient Egypt was united under the Middle Kingdom.
  This dynasty traces its origins to a nomarch of Thebes, "Intef the Great, son of Iku", who is mentioned in a number of contemporary inscriptions. However, his immediate successor Mentuhotep I is considered the first king of this dynasty.
