Takelot I was the son of Osorkon I and Queen Tashedkhons who ruled Egypt for thirteen years according to Manetho. Takelot married Queen Kapes who bore him Osorkon II. Initially, Takelot was believed to be an ephemeral Dynasty 22 Pharaoh since no monuments at Tanis or Lower Egypt could be conclusively linked to his reign, or mentioned his existence, except for the famous Stela of Pasenhor, which dates to Year 37 of Shoshenq V. However, since the late 1980s, Egyptologists have assigned several documents mentioning a king Takelot in Lower Egypt to him rather than Takelot II. Takelot I's reign was relatively short when compared to the three decades-long reigns of his father Osorkon I and son, Osorkon II. Takelot I, rather than Takelot II, was the kingHedjkheperre Setepenre Takelot who is attested by a Year 9 stela from Bubastis as well as the owner of a partly robbed Royal Tomb at Tanis which belonged to this ruler as the German Egyptologist Karl Jansen-Winkeln reported in a 1987 Varia Aegyptiaca 3, pp. 253–258 paper. Evidently, both king Takelots used the same royal prenomen: Hedjkheperre Setepenre. The main difference between Takelot I and II is that Takelot I never employed the Theban-inspired epithet 'Si-Ese' "Son of Isis" in his titulary, unlike Takelot II. As Kenneth Kitchen writes in the third edition of his book on The Third Intermediate Period in Egypt:
Tomb
The evidence that the royal Tanitetomb belonged to Takelot I was suggested long ago by the presence of grave goods found within the burial which mentioned his known parents: "namely a Gold Bracelet and an alabaster Jar of Osorkon I, and an Ushabti figure of Queen Tashedkhons." In addition, a heart scarab found in the king's burial gave his name simply as "Takelot Meryamun" without the Si-Ese epithet used by Takelot II. Recent confirmation of this circumstantial evidence was published by the German scholar :de:Karl Jansen-Winkeln|Jansen-Winkeln in 1987. His examination of several inscriptions written on the tomb's walls proved beyond doubt that the person buried here could only be Takelot I, Osorkon II's father. Jansen-Winkeln's conclusions have been accepted by Egyptologists today including Professor Kenneth Kitchen. Osorkon II arranged for this aforementioned inscription to be carved on a scene in his tomb where Osorkon is depicted adoring Osiris and Udjo. Above the inscription was carved the cartouche of Osorkon II and the following text: "A Son, furbishing the one who created him." This text establishes that Osorkon II honoured his father by reburying him in the Tanite royal tomb complex. Takelot I's final resting place forms the third chamber of Osorkon II's tomb which means that Osorkon II interred his father within the walls of his own tomb. Takelot I was buried in a usurped Middle Kingdom sarcophagus that was inscribed with his own cartouche.
Authority
Takelot I's authority was not fully recognised in Upper Egypt, and Harsiese A, or another local Theban king, challenged his power there. Several Nile Level Texts at Thebes mention two sons of Osorkon I—namely, the High Priests of AmunIuwelot and Smendes III in Years 5, 8 and 14 of an anonymous king who can only be Takelot I, since Takelot I was their brother. Uniquely, however, the Quay Texts specifically omit any reference to the identity of the king himself. This might suggest that there was a dispute in the royal succession following Osorkon I's death in Upper Egypt, which seriously impaired Takelot I's control there. Harsiese A, as the son of the High PriestShoshenq C and grandson of Osorkon I, or a hypothetical king named Maatkheperre Shoshenq must have appeared as a rival. The Theban priests henceforth chose to avoid any involvement in this dispute by deliberately leaving the name of the king in the Quay Texts 'Blank' rather than choosing sides, as G. Broekman notes in his study of the Karnak Quay Texts. This situation was ultimately later resolved by Osorkon II who is clearly attested as Pharaoh at Thebes by his 12th Regnal Year, according to Nile Level Texts No.8 and No.9.
