Amenemhat III in Wikipedia
Amenemhat III, also spelled Amenemhet III was a pharaoh of the Twelfth Dynasty of Egypt. He ruled from c.1860 BC to c.1814 BC,
the latest known date being found in a papyrus dated to Regnal Year 46, I Akhet 22 of his rule. He is regarded as the greatest
monarch of the Middle Kingdom. He may have had a long coregency (of 20 years) with his father, Senusret III.
Towards the end of his reign he instituted a coregency with his successor Amenemhet IV, as recorded in a now damaged rock
inscription at Konosso in Nubia, which equates Year 1 of Amenemhet IV to either Year 46, 47 or 48 of his reign. His daughter,
Sobekneferu, later succeeded Amenemhat IV, as the last ruler of the 12th Dynasty. Amenemhat III's throne name, Nimaatre, means
"Belonging to the Justice of Re."
He built his first pyramid at Dahshur (the so-called "Black Pyramid") but there were construction problems and this was
abandoned. Around Year 15 of his reign the king decided to build a new pyramid at Hawara. The pyramid at Dahshur was used
as burial ground for several royal women.
His mortuary temple at Hawara (near the Fayum), is accompanied by a pyramid and was known to Herodotus and Diodorus Siculus as
the "Labyrinth". Strabo praised it as a wonder of the world. The king's pyramid at Hawara contained some of the most complex
security features of any found in Egypt and is perhaps the only one to come close to the sort of tricks Hollywood associates
with such structures. Nevertheless, the king's burial was robbed in antiquity. His daughter, Neferuptah, was buried in a
separate pyramid (discovered in 1956) 2 km southwest of the king's.
The vizier Kheti held this office around year 29 of king Amenemhet III's reign. The Rhind Mathematical Papyrus is thought to
have been originally composed during Amenemhat's time.
