Menmaatre Seti I (or Sethos I in Greek) was the second pharaoh of the Nineteenth Dynasty of Egypt during the New Kingdom period, ruling c. 1294 or 1290 BC to 1279 BC. He was the son of Ramesses I and Sitre, and the father of Ramesses II (commonly known as Ramesses the Great).The name 'Seti' means "of Set", which indicates that he was consecrated to the god Set (also termed "Sutekh" or "Seth"). As with most pharaohs, Seti had several names. Upon his ascension, he took the prenomen "mn-m3't-r' ", usually vocalized in Egyptian as Menmaatre (Established is the Justice of Re). His better known nomen, or birth name, is transliterated as "sty mry-n-ptḥ" or Sety Merenptah, meaning "Man of Set, beloved of Ptah". Manetho incorrectly considered him to be the founder of the 19th Dynasty, and gave him a reign length of 55 years, though no evidence has ever been found for so long a reign.
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.
