The son of Shoshenq I and his chief consort, Karomat A, Osorkon I was the second king of Egypt's 22nd Dynasty and ruled around 922 BC – 887 BC. He succeeded his father Shoshenq I who probably died within a year of his successful 923 BC campaign against the kingdoms of Israel and Judah. Osorkon I's reign is known for many temple building projects and was a long and prosperous period of Egypt's History. His highest known date is a "Year 33 Second Heb Sed" inscription found on the bandage of Nakhtefmut's Mummy which held a bracellet inscribed with Osorkon I's praenomen: Sekhemkheperre. This date can only belong to Osorkon I since no other early Dynasty 22 king ruled for close to 30 years until the time of Osorkon II. Other mummy linens which belong to his reign include three separate bandages dating to his Regnal Years 11, 12, and 23 on the mummy of Khonsmaakheru in Berlin. The bandages are anonymously dated but definitely belong to his reign because Khonsmaakheru wore leather bands that contained a menat-tab naming Osorkon I. Secondly, no other king who ruled around Osorkon I's reign had a 23rd Regnal Year including Shoshenq I who died just before the beginning of his Year 22.

Osorkon I. war der 2. altägyptische Pharao (König) der 22. Dynastie (Dritte Zwischenzeit). Er regierte um 925 – 890 v. Chr. (als Indizien gelten eine Mumienbinde mit dem Jahr "33", Laufbahn des Iuwelot, Tod des Mitregenten Scheschonq II. mit ca. 50 Jahren, Amtszeiten der Amunpriester).

Manéthon l’appelle Osorkon et lui compte quinze ans de règne de -924 à -890 / -889. Il est le fils de Sheshonq  et Karoma . Il maintient l’ordre instauré par son père en composant avec le clergé d’Amon à Thèbes qui à du mal à reconnaître cette dynastie d’étrangers. Il créé une résidence près de El-Lahoun  et il orne d’or les temples d’Héliopolis.
