Following the unification, Mentuhotep II reformed Egypt's government. To reverse the decentralization of power, which contributed to the collapse of the Old Kingdom and marked the First Intermediate Period, he centralized the state in Thebes to strip nomarchs of some of their power over the regions. Mentuhotep II also created new governmental posts whose occupants were Theban men loyal to him, giving the pharaoh more control over his country. Officials from the capital travelled the country regularly to control regional leaders.
