On July 22–23, 1952, the Free Officers Movement, led by Muhammad Naguib and Gamal Abdel Nasser, launched a coup d'état (Egyptian Revolution of 1952) against the king. Farouk I abdicated the throne to his son Fouad II, who was, at the time, a seven month old baby. The Royal Family left Egypt some days later and the Council of Regency, led by Prince Muhammad Abdel Moneim was formed, The council, however, held only nominal authority and the real power was actually in the hands of the Revolutionary Command Council, led by Naguib and Nasser.
