Menmaatre Seti I (also called Sethos I after the Greeks) was a Pharaoh of Ancient Egypt (Nineteenth dynasty of Egypt), the son of Ramesses I and Queen Sitre, and the father of Ramesses II. As with all dates in Ancient Egypt, the actual dates of his reign are unclear, and various historians claim different dates, with 1294 BC – 1279 BC and 1290 BC to 1279 BC being the most commonly used by scholars today. These two dates are dependent on the chronological system used by a particular Egyptologist. The ancient Egyptians counted time from a king’s accession day as Year One of a Pharaoh’s reign. When a Pharaoh died or fell from power, the following day immediately became Year number 1 of his successor’s reign. To identify Seti I’s Year 1 with a specific BC year, a chronologist must not only take into account the existing evidence from various sources, but which set of interpretations that he/she finds valid, so different chronologists and historians can have different views on the subject.
The name Seti means “of Set”, which indicates that he was consecrated to the god Set (commonly “Seth”). As with most Pharaohs, Seti had a number of names. Upon his ascension, he took the prenomen mn-m3‘t-r‘, which translates as Menmaatre in Egyptian, meaning “Eternal is the Justice of Re.” His better known nomen or birth name is technically 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.
