The Ninth Dynasty of ancient Egypt is often combined with the 7th, 8th, 10th and early 11th Dynasties under the group title First Intermediate Period. The dynasty that seems to have supplanted the 8th Dynasty is extremely obscure. The takeover by the rulers of Herakleopolis was violent and is reflected in Manetho's description of Achthoes, the founder of the dynasty, as 'more terrible than his predecessors', who 'wrought evil things for those in all Egypt".

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.

Heracleopolis Magna or Heracleopolis, is the Roman name of the capital of the 20th nome of ancient Upper Egypt, known in Ancient Egyptian as Het-Nesut. The site is located approximately 15 km (9.3 mi) west of the modern city of Beni Suef, in the Beni Suef Governorate of Egypt.

Mentuhotep II, also known under his prenomen Nephepetre, was an ancient Egyptian pharaoh circa 2061–2010 BCE, the sixth ruler of the Eleventh Dynasty. He is credited with reuniting Egypt, thus ending the turbulent First Intermediate Period and becoming the first pharaoh of the Middle Kingdom. He reigned for 51 years, according to the Turin King List. Mentuhotep II succeeded his father Intef III on the throne and was in turn succeeded by his son Mentuhotep III.

Sankhkare Mentuhotep III of the Eleventh Dynasty was Pharaoh of Egypt during the Middle Kingdom. He was assigned a reign of 12 years in the Turin Canon.

Merikare was an ancient Egyptian pharaoh of the 10th Dynasty who lived toward the end of the First Intermediate Period. Purportedly inspired by the teaching of his father, he embarked on a semi-peaceful coexistence policy with his southern rivals of the 11th Dynasty, focusing on improving the prosperity of his realm centered on Herakleopolis instead of waging an open war with Thebes. His policy was not rewarded, and shortly after his death his kingdom was conquered by the Theban Mentuhotep II, marking the beginning of the Middle Kingdom. The existence of his pyramid has historically been ascertained, although it has not yet been discovered.

The Middle Kingdom of Egypt is the period in the history of ancient Egypt following a period of political division known as the First Intermediate Period. The Middle Kingdom lasted from approximately 2050 to 1710 BC, stretching from the reunification of Egypt under the reign of Mentuhotep II in the Eleventh Dynasty to the end of the Twelfth Dynasty. The kings of the Eleventh Dynasty ruled from Thebes and the kings of the Twelfth Dynasty ruled from el-Lisht.
