From Shoshenq III's eighth regnal year, his reign was marked by the loss of Egypt's political unity, with the appearance of Pedubast I at Thebes. Henceforth, the kings of the 22nd Dynasty only controlled Lower Egypt. The Theban High Priest Osorkon B (the future Osorkon III) did date his activities at Thebes and (Upper Egypt) to Shoshenq III's reign, but this was solely for administrative reasons since Osorkon did not declare himself king after the death of his father, Takelot II. On the basis of Osorkon B's well known Chronicle, most Egyptologists today accept that Takelot II's 25th regnal year is equivalent to Shoshenq III's 22nd year.
