What happened 1292 AD

Horemheb also died without surviving children, having appointed his vizier, Pa-ra-mes-su, as his heir. This vizier ascended the throne in 1292 BC as Ramesses I, and was the first pharaoh of the Nineteenth Dynasty.

The last two members of the Eighteenth Dynasty—Ay and Horemheb—became rulers from the ranks of officials in the royal court, although Ay might also have been the maternal uncle of Akhenaten as a fellow descendant of Yuya and Tjuyu. Ay may have married the widowed Great Royal Wife and young half-sister of Tutankhamun, Ankhesenamun, in order to obtain power; she did not live long afterward. Ay then married Tey, who was originally Nefertiti's wet-nurse. Ay's reign was short. His successor was Horemheb, a general during Tutankhamun's reign whom the pharaoh may have intended as his successor in the event that he had no surviving children, which came to pass. Horemheb may have taken the throne away from Ay in a coup d'état. Although Ay's son or stepson Nakhtmin was named as his father/stepfather's Crown Prince, Nakhtmin seems to have died during the reign of Ay, leaving the opportunity for Horemheb to claim the throne next.
