Overview
Psusennes I (; Greek Ψουσέννης) was the third pharaoh of the 21st Dynasty who ruled from Tanis between 1047 and 1001 BC. Psusennes is the Greek version of his original name Pasibkhanu or Pasebakhaenniut (in reconstructed Late Egyptian: /pəsiwʃeʕənneːʔə/), which means "The Star Appearing in the City" while his throne name, Akheperre Setepenamun, translates as "Great are the Manifestations of Ra, chosen of Amun." He was the son of Pinedjem I and Henuttawy, Ramesses XI's daughter by Tentamun. He married his sister Mutnedjmet.
Psusennes's tomb, discovered in 1940, is notable for the condition in which it was found. Almost all pharaonic tombs were entirely graverobbed but Psuennes's tomb was one of only two royal tombs discovered in fully intact condition, the other being the tomb of Pharaoh Amenemope. However, the humid climate of Lower Egypt meant only the metal objects had survived.
Reign
Psusennes I's precise reign length is unknown because different copies of Manetho's records credit him with a reign of either 41 or 46 years. Some Egyptologists have proposed raising the 41 year figure by a decade to 51 years to more closely match certain anonymous Year 48 and Year 49 dates in Upper Egypt. However, the German Egyptologist Karl Jansen-Winkeln has suggested that all these dates should be attributed to the serving High Priest of Amun, Menkheperre instead who is explicitly documented in a Year 48 record. Jansen-Winkeln notes that "in the first half of Dyn. 21, [the] HP Herihor, Pinedjem I and Menkheperre have royal attributes and [royal] titles to differing extents" whereas the first three Tanite kings (Smendes, Amenemnisu and Psusennes I) are almost never referred to by name in Upper Egypt with the exception of one graffito and rock stela for Smendes. In contrast, the name of Psusennes I's Twenty-first Dynasty successors such as Amenemope, Osorkon the Elder, and Siamun appear frequently in various documents from Upper Egypt while the Theban High Priest Pinedjem II who was a contemporary of the latter three kings never adopted any royal attributes or titles in his career.
Hence, two separate Year 49 dates from Thebes and Kom Ombo could be attributed to the ruling High Priest Menkheperre in Thebes instead of Psusennes I but this remains uncertain. Psusennes I's reign has been estimated at 46 years by the editors of the Handbook to Ancient Egyptian Chronology.
