In 1940,
Prince Muhammad Abdel Moneim, son of Egypt's last
Khedive Abbas Hilmi II, proposed to Neslişah. Neslişah rejected the proposal, but accepted it following pressure from her father, despite her younger sister Hanzade, who later married another Egyptian prince a week before her sister, having volunteered to marry Moneim in her stead, an offer her father refused. The marriage took place on 26 September 1940 in
el-Orouba Palace, Cairo, and she was given the title
Sahibat-al Sumuw Al-Amira Neslishah (Her Highness Princess Neslishah). Two years earlier, Abdel Moneim, heir to a
US$50,000,000 fortune, had obtained permission from his second cousin King
Farouk of Egypt to marry Princess
Myzejen Zogu (1909–1969), sister of King
Zog I of Albania. However, the marriage never took place and Prince Abdel Moneim married Neslişah instead. On 16 October 1941, she gave birth to
Prince Abbas Hilmi. He was followed three years later by Princess Ikbal, born on 22 December 1944. In the absence of a
Queen consort, Neslişah
de facto served as such by virtue of her position as the wife of the Prince regent. Her few official appearances during her husband's regency focused on charity work. Like the royal consorts who preceded her, she attended sporting events such as polo matches and the international tennis tournament final. Around 1943, Neslişah's father, Ömer Faruk, developed an increased interest in his cousin
Mihrişah Sultan, the daughter of
Şehzade Yusuf Izzeddin. The turbulence of the relationship between Faruk and his wife Sabiha was also a public knowledge. She and her sisters sided with their mother. Faruk accused Sabiha of turning their daughters against him.
Murat Bardakçı opines that he had already fallen in love with Mihrişah and the issue of the council was merely an excuse. In 1948, after twenty-eight years of marriage, Faruk divorced Sabiha, and married Mihrişah, after which Sabiha moved to live near her. Neslişah never came to accept her father's second wife. Prince Abdel Moneim's regency lasted ten months. The
Egyptian Revolutionary Command Council formally abolished the monarchy on 18 June 1953. In 1957, Abdel Moneim and Neslişah were arrested. Again forced into exile, Neslişah was released from prison after the
President of the Republic of Turkey intervened and demanded her release. She subsequently lived for a short time in Europe, then returned to her native Turkey. In 1963, she reclaimed Turkish citizenship, and took the surname Osmanoğlu, which had been assigned to members of the Ottoman former imperial family. Prince Abdel Moneim died in 1979 in
Istanbul, where Princess Neslişah continued to live with her unmarried daughter Ikbal. ==Death==
