Ramses had many children
Ramses II had almost 200 concubines and wives. Nefertari, his first Royal Wife, was most certainly his favorite queen. Her tomb QV66 is the most impressive in the Valley of the Queens, with superb wall painting décor that is considered one of ancient Egypt's best achievements.
Not just for the number of wives and concubines he had, but also for the number of offspring he fathered, this great pharaoh is remembered. Historians can't be certain of the actual number, although it's probably close to 100. (between 48 to 50 sons, and 40 to 53 daughters). However, just a few of these lived, and his immediate successor was his third son, not his first. He outlived many of his offspring due to his long reign, and his 13th son eventually succeeded him.
Unlike many other pharaohs, his family is commemorated through monuments such as Nefertari's tiny temple at Abu Simbel and her large tomb in the Valley of the Queens. He also erected one of Egypt's most distinctive and largest tombs for a number of his sons near his tomb in the Valley of the Kings on the West Bank at Luxor (ancient Thebes). He had sculptures or images of his sons and daughters inscribed on a number of his construction projects around Egypt. These monuments and carvings were made to suggest his children to the gods' clemency, not to brag about his progeny's fertility. The majority of these also mentioned the name of the son or daughter.
