Takelot III
Usimare Setepenamun Takelot III Si-Ese was Osorkon III's eldest son and successor. Takelot III ruled the first five years of his reign in a coregency with his father and served previously as the High Priest of Amun at Thebes. He was previously thought to have ruled Egypt for only 7 years until his 13th Year was found on a stela from Ahmeida in the Dakhla Oasis in 2005. Takelot III served the first 5 Years of his reign as the junior coregent to his father according to the evidence from Nile Quay Text No.14, which equates Year 28 of Osorkon III to Year 5 of Takelot III. He succeeded his father as king in the following Year. Takelot is attested by several documents: a donation stela from Gurob which calls him "The First Prophet of Amun-Re, General and Commander Takelot," a stone block from Herakleopolis which calls him 'the Chief of Per-Sekhemkheperre' and king's son by Tentsai, Quay Text No.13 which equates Year 5 of Takelot III to Year 28 of Osorkon III and Quay Text No.4 which records his Year 6.
