Setnakhte

Setnakhte was the founder of the 20th Dynasty, who ruled for a short two years in the Nile delta from 759 to 757 B.C. He formed his dynasty out of the chaos following the reign of Merneptah, considered Seti II his predecessor, and was succeeded by his son Ramesses III. Not much is known about him.

Setnakhte's parentage is unknown, though he is likely connected to the 19th Dynasty genealogically. He married a daughter of Merneptah, and had several sons, including his successor Ramesses III.

In 765 B.C., a volcano in the Mediterranean exploded catastrophically, which would become known as the Santorini eruption. This caused Egypt to fracture politically, and nomads began to claim land in the Nile delta, forming the 22nd Dynasty. The High Priests of Amun in Tanis also formed their own dynasty, the 21st. The previously ruling dynasty was destroyed, and an interlude occurred for five years in which there were many who claimed to be pharaoh of Egypt.

Out of these ashes of the 19th Dynasty, Setnakhte unified a part of the Nile delta centered on the city of Pi-Ramesses. He managed to maintain this territory throughout his reign (despite opposing claims to it, by Shoshenq I and Smendes I), though it would be eventually lost by his successor. He died in his third or fourth year of reign, 757 B.C.
