Ramesses IX was the eighth king of the Twentieth Dynasty. He is thought to have reigned for about seventeen or more years. During his reign, there was a scandal in which the tombs in the Theban necropolis were being robbed. There were also campaigns by Libyan bandits. He had a son, Montuherkhopshef, who did not live to succeed Ramesses. His tomb was found in the Valley of the Kings.
