Horemheb (sometimes spelled Horemhab or Haremhab and meaning Horus is in Jubilation) was the last Pharaoh of the 18th Dynasty from either 1319 BC to late 1292 BC, or 1306 to late 1292 BC (if he ruled for 14 years) although he was not related to the preceding royal family and is believed to have been of common birth.
Before he became pharaoh, Horemheb was the commander in chief of the army under the reigns of Tutankamun and Ay. After his accession to the throne, he reformed the state and it was under his reign that official action against the preceding Amarna rulers began.
Horemheb demolished monuments of Akhenaten, reusing their remains in his own building projects, and usurped monuments of Tutankhamun and Ay. Horemheb presumably remained childless since he appointed his vizier Paramesse as his successor, who would assume the throne as Ramesses I.
