Mentuhotep IV (Nebtawyre)

Mentuhotep IV (throne-name Nebtawyre) was the last king of Dynasty 11, omitted from some king-lists. A major quarrying expedition of his reign into the Wadi Hammamat was led by his vizier Amenemhat, very probably the future Amenemhat I and founder of Dynasty 12; the nature of the dynastic transition, possibly a usurpation, is debated.
