Seti I [SEP] Reign
After the enormous social upheavals generated by Akhenaten's religious reform, Horemheb, Ramesses I and Seti I's main priority was to re-establish order in the kingdom and to reaffirm Egypt's sovereignty over Canaan and Syria, which had been compromised by the increasing external pressures from the Hittite state. Seti, with energy and determination, confronted the Hittites several times in battle. Without succeeding in destroying the Hittites as a potential danger to Egypt, he reconquered most of the disputed territories for Egypt and generally concluded his military campaigns with victories. The memory of Seti I's military successes was recorded in some large scenes placed on the front of the temple of Amun, situated in Karnak.
