Derr was Penne. The dynasty of Ramessesnakht In Thebes, the high-priesthood came under the control of Ramessesnakht and his family at the time of Ramesses IV, possibly owing to Ramessesnakht's father Merybaste's high control over the country's financial institutions. Ramessesnakht was officially Ramesses VI's Vizier of the South and his power grew at the expense of that of the pharaoh in spite of the fact that Iset was connected to the Amun priesthood as well "in her role as God's Wife of Amun or Divine Adoratice". If fact, Ramessesnakht most likely oversaw the construction of the funerary building of Iset in the tomb complex K93.12, and while, as the Egyptologist Daniel Polz puts it, "he and his relatives were the most powerful individuals in Egypt at the end of the Twentieth Dynasty", his activities were not directed against royal interests. Ramessesnakht often attended the distribution of supplies to workmen and controlled much of the activity connected with the construction of the king's tomb, possibly because the treasury of the high-priest of Amun was now at least partially funding these works. Ramessesnakht's son Usermarenakhte was made into the Steward of Amun and became administrator of large swaths of land in Middle Egypt. He also inherited the role of Merybaste as controller of the country's taxes, ensuring that Ramessesnakht's family was in full control of both the royal treasury and the treasury of Amun. Further high offices such as those of the second and third priests and of "god's father of Amun" were given to people who entered Ramesesnakht's family by marriage. Ramessesnakht was powerful enough to build for himself one of the largest funerary establishments of the entire Theban necropolis at the end of the New Kingdom, when royal building projects including Ramesses VI's usurped mortuary temple had been abandoned. Ramessesnakht's monument, in Dra' Abu el-Naga', reused an earlier building dating back to the Seventeenth or Eighteenth Dynasty and was refurbished to show the political and economic standing of its owner. Overall, Egyptologists now estimate that Ramessesnakht and his dynasty essentially established a second centre of power in Upper Egypt, seemingly on the behalf of the Twentieth Dynasty kings who ruled from Memphis and Pi-Ramesses in Lower Egypt. This effectively made Thebes into the religious capital of Egypt as well as an administrative one on a par with its northern counterpart, laying the foundations for the rise of the Twenty-first Dynasty
