أمنمحات الأول
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.
