Herihor
Herihor (flourished 11th century BCE) was an ancient Egyptian army officer and high priest of Amon at Karnak (Thebes), who founded a dynasty of priest-kings that ruled southern Egypt when the country became disunited in the last years of the 20th dynasty (1190–1075 BCE).
Stela of Herihor, High Priest of Amun at Thebes, c. 1090-1080 BCE. Rijksmuseum van Oudheden, Leiden. Herihor’s origins are altogether obscure. He is believed to have advanced through the military ranks during the troubled reign of Ramses XI, the last king of the 20th dynasty. It was probably Herihor who expelled the viceroy of Kush from Thebes around the 19th year of Ramses’ reign. At the same time, he began a new dating scheme, probably to mark his own rise to power.
