Overview
Menpehtyre Ramesses I (or Ramses) was the founding pharaoh of ancient Egypt's 19th Dynasty. The dates for his short reign are not completely known but the timeline of late 1292–1290 BC is frequently cited as well as 1295–1294 BC. While Ramesses I was the founder of the 19th Dynasty, his brief reign mainly serves to mark the transition between the reign of Horemheb, who had stabilized Egypt in the late 18th Dynasty, and the rule of the powerful pharaohs of his own dynasty, in particular his son Seti I, and grandson Ramesses II.
Origins
Originally called Pa-ra-mes-su, Ramesses I was of non-royal birth, being born into a noble military family from the Nile Delta region, perhaps near the former Hyksos capital of Avaris. He was a son of a troop commander called Seti. His uncle Khaemwaset, an army officer, married Tamwadjesy, the matron of Tutankhamun's Harem of Amun, who was a relative of Huy, the viceroy of Kush, an important state post. This shows the high status of Ramesses' family. Ramesses I found favor with Horemheb, the last pharaoh of the tumultuous Eighteenth Dynasty, who appointed the former as his vizier. Ramesses also served as the High Priest of Set – as such, he would have played an important role in the restoration of the old religion following the Amarna heresy of a generation earlier, under Akhenaten.
Horemheb himself had been a nobleman from outside the immediate royal family, who rose through the ranks of the Egyptian army to serve as the royal advisor to Tutankhamun and Ay and, ultimately, pharaoh. Since Horemheb had no surviving children, he ultimately chose Ramesses to be his heir in the final years of his reign presumably because Ramesses I was both an able administrator and had a son (Seti I) and a grandson (the future Ramesses II) to succeed him and thus avoid any succession difficulties.
