Nefertiti

Nefertiti was the wife of Akhenaten. Nefertiti, which means "the beautiful woman has come", is one of the most famous and beloved of all ancient Egyptian queens. One of the best known Egyptian treasures is a bust of her that is now placed in the Egyptian Museum in Berlin.
Nefertiti was married to Akhenaten and while living in Memphis gave birth to six daughters. Nefertiti moved with her husband to Akhetaten where, as shown on wall scenes, she participated in all the religious ceremonies. It was only through the combined royal pair that the full blessing of god Aten could be bestowed.
As compared to other ancient Egyptian queens, Nefertiti was displayed with an outstanding prominence. Her name was usually enclosed in a royal cartouche, and the number of her statues and drawings are more than those of Akhenaten. Some have even claimed that it was Nefertiti, not Akhenaten, who instigated the monotheistic religion of Aten. It was around the 15th regnal year of Akhenaten that Nefertiti mysteriously disappeared from the scene. It could be that she died, although, to this date, there are no existing indications of that. Some scholars believe that she was banished, and that she lived the rest of her life in the northern palace.
Two reasons could be used for explaining Nefertiti's banishment. First, it could be that she disapproved of the slow return to the worship of Amon, which was taking place at that time, with Smenkhkare becoming co-regent and the moving back to Thebes to re-open some temples. The second opinion is that perhaps she believed that Akhenaten was losing touch with his people and angering them by destroying all other gods besides his own, thus she could have been banished by Akhenaten for going against his religion. Whatever the case, she is replaced by her eldest daughter, Meritaten.
