Ramesses II was also called Ramesses the Great and he lived for 96 years. It is believed that he had as many as fifty sons and fifty daughters, though only a few of them are known to us. His chief, and most likely favorite wife was Nefertari. In the seventh year of his father's (Seti I) reign, Ramesses II became co-ruler of Egypt. Ramesses II and his father began many restoration and building projects. These included the building of several temples and the restoration of other shrines and complexes throughout Egypt. He built a mortuary complex at Abydos in honor of Osiris and the famed Ramesseum. Having outlived many of his older sons, his 13th son ascended to the throne upon his death in 1298 B.C.E.
