Answer
Ramesses II, the third pharaoh of the 19th Dynasty of Ancient Egypt, was the only king whose monuments Horemheb, an Egyptian military leader and pharaoh of the 18th Dynasty, did not usurp. This act of respect was likely due to the great admiration and reverence Horemheb held for Ramesses II's achievements, military prowess, and contributions to Egypt's prosperity and grandeur during his reign.
