Usermaatre Setepenamun Takelot III Si-Ese (reigned 774–759 BC) was Osorkon III's eldest son and successor. Takelot III ruled the first five years of his reign in a coregency with his father, according to the evidence from Nile Quay Text No.13 (which equates Year 28 of Osorkon III to Year 5 of Takelot III), and succeeded his father as king the following year. He 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.[1]
