The Twenty-Fourth Dynasty was a short-lived group of pharaohs who had their capital at Sais in the western Nile Delta.

Tefnakht I formed an alliance of the Delta kinglets, with whose support he attempted to conquer Upper Egypt; his campaign attracted the attention of the Nubian king, Piye, who recorded his conquest and subjection of Tefnakhte of Sais and his peers in a well-known inscription.

However, Olivier Perdu[1] has now argued that a certain Shepsesre Tefnakhte of Sais was not, in fact, Piye's famous nemesis.

Perdu published a recently discovered donation stela which came from a private collection; the document is dated to Year 2 of Necho I of Sais and is similar in style, epigraphy and text with the donation stela of Shepsesre.

Both Tefnakht II and Necho I ruled as local Saite kings during the Nubian era under Taharqa.
