He is thought to have reigned from 1186 to 1155 BC and is considered to be the last great monarch of the New Kingdom to wield any substantial authority over Egypt.
His long reign saw the decline of Egyptian political and economic power, linked to a series of invasions and internal economic problems that also plagued pharaohs before him.
He has also been described as "warrior Pharaoh" due to his strong military strategies.
He led the way by defeating the invaders known as "the Sea People", who had caused destruction in other civilizations and empires.

Duatentopet or Tentopet was an Ancient Egyptian queen of the 20th dynasty, the wife of Pharaoh Ramesses IV, and mother of Ramesses V. Even though the identity of Ramesses IV's wife has not been clearly stated in history, she is considered the most likely candidate by virtue of the titles she was given and which were found listed in her tomb (QV74).
In the Karnak temple complex, an Adoratrix named Tentopet is shown with Ramesses III in the Temple of Khonsu.
It is thought likely that Tentopet and Queen Duatentopet were the same person, and that she was a daughter of Ramesses III.
This would make her a sister, or a half-sister, of her husband.
