King Hedjkheperre Setepenamun Harsiese or Harsiese A, is viewed by the Egyptologist Kenneth Kitchen in his Third Intermediate Period in Egypt, to be both a "High Priest of Amun" and the son of the High Priest of Amun Shoshenq C.
One of the most important of these people was the High Priest of Amun Shoshenq C, son of Osorkon I, who served in office during his father's reign at Thebes.
Harsiese A, as the son of the High Priest Shoshenq C and grandson of Osorkon I, or a hypothethical king named Maatkheperre Shoshenq must have appeared as a rival.
Kenneth Kitchen, in his latest 1996 edition of '’The Third Intermediate Period in Egypt (c.1100–650 BC)’', maintains that Shoshenq II was the High Priest of Amun Shoshenq C, son of Osorkon I and Queen Maatkare, who was appointed as the junior coregent to the throne but predeceased his father.
