Egyptologist Morris Bierbrier also dated Shoshenq I's accession "between 945–940 BC" in his 1975 book concerning the genealogies of Egyptian officials, who served during the late New Kingdom and Third Intermediate Period.

This development would also account for the mostly unfinished state of decorations of Shoshenq's building projects at the Great Temple of Karnak where only scenes of the king's Palestinian military campaign are fully carved.

[10][11] Ido Koch in his 2021 book considered Schneider's chronology of Egyptian kings as a valuable integrative study.

The egyptologist Kenneth Kitchen proposes that Shoshenq's successor, Osorkon I, lavished 383 tons of gold and silver on Egyptian temples during the first four years of his reign and correlate it directly to the looting,[16] while the archaeologist Israel Finkelstein claims that the looting narrative in question "should probably be seen as a theological construct rather than as historical references".

He also held his father's title of Great Chief of the Ma or Meshwesh, which is an Egyptian word for Ancient Libyans.

Significantly, his uncle Osorkon the Elder had already served on the throne for at least six years in the preceding 21st Dynasty; hence, Shoshenq I's rise to power was not wholly unexpected.

As king, Shoshenq chose his eldest son, Osorkon I, as his successor and consolidated his authority over Egypt through marriage alliances and appointments.

He assigned his second son, Iuput A, the prominent position of High Priest of Amun at Thebes as well as the title of Governor of Upper Egypt and Commander of the Army to consolidate his authority over the Thebaid.

This is attested, in part, by the discovery of a statue base bearing his name from the Lebanese city of Byblos, part of a monumental stela from Megiddo bearing his name, and a list of cities in the region comprising Syria, Philistia, Phoenicia, the Negev, and the Kingdom of Israel, among various topographical lists inscribed on the walls of temples of Amun at al-Hibah and Karnak.

The sole funerary object linked to Shoshenq I is a canopic chest of unknown provenance that was donated to the Egyptian Museum of Berlin (ÄMB 11000) by Julius Isaac in 1891.

However, Troy Sagrillo in a GM 205 (2005) paper observes that "there are only a bare handful of inscribed blocks from Tanis that might name the king (i.e. Shoshenq I) and none of these come from an in situ building complex contemporary with his reign.

The funerary cult surrounding his "House of Millions of Years of Shoshenq, Beloved of Amun" was functioning several generations after its establishment at the temple (Ibrahem Aly Sayed 1996, p. 14).

[31]Sagrillo concludes by observing that if Shoshenq I's burial place was located at Memphis, "it would go far in explaining why this king's funerary cult lasted for some time at the site after his death.

His mummy was discovered to contain various gold bracelets, amulets and precious carnelian objects, and give a small hint of the vast treasures that would have adorned Shoshenq I's tomb.
