The Annal stone gives absolutely no indication of a division of the Egyptian realm. Barta, TeVelde, Wilkinson and Edwards argue that the theory of state division is untenable. An administrative reorganization or split in the priesthood sects is more likely. During his time on the throne, Peribsen founded an administrative center called "The white house of treasury" as well as a new royal residence, called the "protection of Nubt", located near Ombos ("Nubt" being the Ancient Egyptian name of Naqada). The administrative titles of scribes, seal-bearers and overseers were adjusted to correspond to the divided bureaucratic state administration. For example, titles like "sealer of the king" were changed into "sealer of the king of Upper Egypt". This bureaucratic reform may indicate an attempt by Peribsen to limit the power of these officials, further evidence for a bloated and unwieldy state administration under Nynetjer. The administration system under Peribsen and Sekhemib had a clear and well-defined hierarchy; as an example, from highest to the lowest rank: Treasury house (royal and therefore highest in ranking) → pension office → property → vineyards → private vineyard (property of citizens and therefore lowest in ranking). King Khasekhemwy, the last ruler of the Second dynasty, was able to re-unify the state administration of Egypt and therefore unite the whole of Ancient Egypt. He brought the two treasury houses of Egypt under the control of the "House of the King", bringing them into a new, single administration centre. Peribsen also founded royal edifices such as "Per-nubt" ("house of Ombos") and "Per-Medjed" ("house of meetings") and created several cities of economic importance. Their names, "Afnut" ("city of the headdress-makers"), "Nebj" ("protector's city"), "Abet-desheret" ("city of the red granite jars") and "Huj-setjet" ("city of the Asians'), are mentioned on numerous clay seals alongside Peribsen's serekh, often preceded by the phrase "visit of the king at ...". Inscriptions on stone vessels also mention an "ini-setjet" ("tribute of the people of Sethroë"), which might indicate that Peribsen founded a cult centre for the deity Seth in the Nile Delta. This may suggest Peribsen ruled over the whole of Egypt, or, at least, that he was accepted as king across all of Egypt.
