Osorkon I

Osorkon I was the second pharaoh of the 22nd Dynasty, who ruled a large section of the Nile delta centered on Bubastis for an uncertain period of time ending before 740 B.C. His rule may have been as long as 23 years, but this is unlikely. He succeeded the founder of the dynasty, Shoshenq I, and was succeeded by his son Takelot I.

Osorkon was the son of Shoshenq I, who founded the 22nd Dynasty following the upheaval of the Santorini eruption. The only son of note of his was Takelot I, who succeeded him.

Some time between 765 and 740 B.C., Osorkon I became pharaoh (how is not known, though given the short time scale involved, he was likely coregent with Shoshenq I). The events of his reign are largely unknown, because his rule closely followed the catastrophic Santorini eruption of 765 B.C. He died some time before 740 B.C.
