Amenemhat I also Amenemhet I and the hellenized form Ammenemes, was the first ruler of the Twelfth Dynasty, the dynasty considered to be the golden-age of the Middle Kingdom of Egypt. He ruled from 1991 BC to 1962 BC.
Amenemhat I was probably the same as the vizier named Amenemhat who led an expedition to Wadi Hammamat under his predecessor Mentuhotep IV, and possibly overthrew him from power. Scholars differ as to whether Mentuhotep IV was killed by Amenemhat I, but there is no independent evidence to suggest this and there may even have been a period of co-regency between their reigns.
Amenemhet I was not of royal lineage, born to Senusret and Nefert who were Nomarchs of one of Egypt's many provinces. The composition of some literary works and, in architecture, the reversion to the pyramid-style complexes of the 6th dynasty rulers are often considered to have been attempts at legitimizing his rule. Amenemhat I moved the capital from Thebes to Itjtawy and was buried in el-Lisht.
