Queen Fawzia (the title of empress was not yet used in Iran at that time) moved to Cairo in May 1945[37] and obtained an Egyptian divorce. The reason for her return was that she viewed Tehran as underdeveloped in contrast to modern, cosmopolitan Cairo.[38][39] She consulted an American psychiatrist in Baghdad for her troubles shortly before she left Tehran.[37] On the other hand, CIA reports claim that Princess Fawzia ridiculed and humiliated the Shah due to his supposed impotence, leading to their separation.[39] In her book Ashraf Pahlavi, twin sister of the Shah, argues that it was the Princess not the Shah who asked for divorce.[19] Fawzia left Iran for Egypt, and despite numerous attempts on the part of the Shah to persuade her to return, she remained put in Cairo.[40] Mohammad Reza told the British ambassador in 1945 that his mother was "probably the main obstacle to the return of the Queen".[40]
