Nebtawyre Mentuhotep IV was the last king of the 11th Dynasty.

Despite being obscure (he is lacking in the official king lists in Abydos), the inscriptions show the organization and makeup of a large expedition.

MentuhotepIV is credited with founding the city of Kuser on the shore of the Red Sea as a harbor for shipbuilding -- all in preparation for his journeys to Punt.
The fact that MentuhotepIV is missing from some king lists and that his vizier came to the throne as Amenemhet I leads to the idea that his vizier may have usurped the throne.
This means, possibly, that Mentuhotep was considered illegitimate, or that the pharaohs of the 12th Dynasty decided to rewrite history to better support their claim to the throne.
