Prince Abbas Hilmi (; born 16 October 1941) is an Egyptian and Imperial Ottoman prince and financial manager. A member of the Muhammad Ali Dynasty, he is the only son of Prince Muhammad Abdel Moneim and his Ottoman wife Princess Neslişah, and grandson of Khedive Abbas Hilmi II Bey. Early life Born in Cairo in 1941, Prince Abbas Hilmi was named after his paternal grandfather Abbas Hilmi II, the last khedive of Egypt. Theirs was the most senior male branch descended from Isma'il Pasha, and thus first in the line of succession to the Egyptian throne by virtue of the 1866 rules of succession. However, those rules were suspended by the British upon their proclamation of a protectorate over Egypt in 1914. Abbas Hilmi II was deposed, and his son Muhammad Abdel Moneim lost his place as heir apparent. The throne passed to Abbas Hilmi II's uncles Hussein Kamel and Fuad I. The Royal Edict of 13 April 1922 specifically excluded Abbas Hilmi II from the succession, although it stated that "this exception shall not apply to his sons and their progeny." This meant that Prince Muhammad Abdel Moneim and his son Prince Abbas Hilmi remained eligible for the throne and retained a senior position in the order of precedence of the Kingdom of Egypt. Prince Abbas Hilmi's two great-grandfathers on his mother's side were Mehmed VI, the last Ottoman sultan, and Abdülmecid II, the last Ottoman caliph. Had the Ottoman monarchy not been abolished in 1922, Prince Abbas Hilmi would have received, in addition to his Egyptian princely title (), the Ottoman title of sultanzade, which was given to the sons of imperial princesses. In July 1952, the Free Officers launched a revolution that led to the forced abdication of King Farouk of Egypt in favour of his infant son King Fuad II. Due to Fuad II's minority, Prince Muhammad Abdel Moneim was chosen by the new military rulers to serve as regent, first as head of a temporary regency body and later as sole prince regent. However, he did not last long in the position, as the Egyptian monarchy was officially abolished on 18 June 1953. Prince Muhammad Abdel Moneim and his wife Neslişah were arrested in 1957 and accused of taking part in an anti-Nasser plot. Their souring relations with the new revolutionary regime forced them into exile. As a result, their son Prince Abbas Hilmi spent
