Mentuhotep II commanded petty campaigns south as far as the Second Cataract in Nubia, which had gained its independence during the First Intermediate Period. He also restored Egyptian hegemony over the Sinai region, which had been lost to Egypt since the end of the Old Kingdom.[7] To consolidate his authority, he restored the cult of the ruler, depicting himself as a god in his own lifetime, wearing the headdresses of Amun and Min.[8] He died after a reign of 51 years and passed the throne to his son, Mentuhotep III.[7]
