Regencies in Egypt

Regencies in Egypt date back to Pharaonic times. Throughout Egypt's long history, there have been several instances of regents assuming power due to the reigning monarch's minority, physical illness or poor mental health. There have also been several cases of coregencies where two monarchs ruled simultaneously.
Ancient Egypt.
Female Regents
Regencies were very frequent during the Pharaonic era, particularly in cases where the new king was too young to rule. In such instances, it was usually the young king's mother (or sometimes step-mother) who would act as regent until the king was old enough to rule by himself. The most famous Ancient Egyptian regent is probably Hatshepsut, who initially served as regent for her young nephew Thutmose III before taking the throne herself and reigning for more than twenty years.
Male Regents
While less common, male regents are known to have taken power during the Pharaonic era.
Co-rule
Coregencies were also very common, and aging monarchs often appointed their sons and heirs as coregents towards the end of their reigns. Most Pharaohs of the Twelfth Dynasty until Amenemhat III had a period of co-rule with their eventual successors.
Ptolemaic Egypt.
The Ptolemaic Dynasty implemented a policy of co-rule starting with Ptolemy II and Arsinoe II. It was common during this dynasty to have husband-wife and sibling pairings ruling over Egypt. Co-rule could also happen between unmarried siblings or parents and children. In at least one case, Egypt had three reigning Pharaohs at the same time with Ptolemy VI, Cleopatra II and Ptolemy VIII.

Medieval Egypt.
During the Middle Ages, Egypt was ruled by a succession of Islamic dynasties, and regencies were not uncommon. A famous example of a female regent is that of the Fatimid Sitt al-Mulk.

Modern Egypt.
The Muhammad Ali Dynasty, which ruled Egypt from 1805 until 1953, witnessed three different regencies.
Regency during Muhammad Ali's illness.
Ibrahim Pasha presided the Regency Council that was formed on 15 April 1848 to run Egypt due to Muhammad Ali Pasha's declining physical and mental health. Legal documents were still written in the latter's name; however, Ibrahim Pasha became the "de facto" ruler of the country from this moment on. On 20 July of the same year, an extraordinary envoy of Ottoman Sultan Abdülmecid I arrived in Alexandria with the "firman" by which the Porte recognized Ibrahim Pasha as Egypt's new "wāli". The latter then travelled to Istanbul, where his investiture took place on 25 August in the presence of the Ottoman Sultan. However, his reign was very brief, and his death occurred shortly after his return to Cairo. He died on 10 November 1848 due to ill health, thus predeceasing his father.
Regency during Farouk I's minority.
A Regency Council was established following the death of King Fuad I, since his son Farouk was still a minor. Prior to his death, Fuad I had named in a formal document the three members who were to serve on the Regency Council: Adli Yakan Pasha (a former Prime Minister who had already died by the time Farouk I became King), Tawfiq Nasim Pasha (another former Prime Minister) and Mahmoud Fakhri Pasha (a former Foreign Minister married to Fuad I's eldest daughter Princess Fawkia). However, Parliament rejected King Fuad I's choices, and appointed three totally different regents: Prince Muhammad Ali (son of the late Khedive Tawfiq Pasha and thus first cousin of King Farouk I), Aziz Ezzat Pasha (a former Foreign Minister married to Behiye Yakan Hanem, another cousin of Farouk I) and Sherif Sabri Pasha (Farouk I's maternal uncle). The Regency Council was formally sworn in on 8 May 1936 in front of a joint session of Parliament. King Farouk I assumed his full constitutional powers upon reaching his age of majority (fixed at 18 years and calculated according to the Islamic calendar) on 29 July 1937.
Regency during Fuad II's minority.
The Revolution of July 1952 did not immediately lead to the abolition of the monarchy. King Farouk I abdicated in favour of his six-month-old son Ahmad Fuad, who ascended the throne as King Fuad II. However, the latter only reigned as a nominal king-in-exile. Initially, his powers were assumed during a week by the Cabinet, headed at the time by Ali Maher Pasha. On 2 August 1952, a temporary regency "body" (not a formal Regency Council) was created. Headed by Prince Muhammad Abdel Moneim (son of the late Khedive Abbas Helmi II and Fuad II's second cousin), the three-member Regency Body also included Bahey El Din Barakat Pasha (a former Minister of Education and Speaker of Parliament) and Rashad Mehanna (a colonel appointed as representative of the Army). The Regency Body was dissolved on 7 September 1952, and Prince Muhammad Abdel Moneim was appointed as sole Prince regent. However, throughout this period, real powers lay in the hands of the Revolutionary Command Council. The monarchy was formally abolished on 18 June 1953: Egypt was declared a republic for the first time in its history, and Muhammad Naguib became its first ever President.
