Pedubast I declares himself king of Egypt, founding the Twenty-third Dynasty in either 835 or 824 BCE.

This local Pharaoh, who is recorded as being of Libyan ancestry, will rule Egypt for twenty-five years according to the redaction of Manetho done by Eusebius.

He first became king at Thebes in Year Eight of Shoshenq III and his highest dated Year is his Twenty-third Year according to Nile Level Text No. 29.

This year is equivalent to Year Thirty-One of Shoshenq III of the Tanis based Twenty-second Dynasty of Egypt; however, since Shoshenq II only controlled Lower Egypt in Memphis and the Delta region, Pedubast and Shoshenq III were not political rivals and may even have established a relationship.
