Idris was King of Libya from 24 December 1951 until his ouster in the 1 September 1969 coup d'état. He ruled over the United Kingdom of Libya from 1951 to 1963, after which the country became known as simply the Kingdom of Libya. Idris had served as Emir of Cyrenaica and Tripolitania from the 1920s until 1951. He was the chief of the Muslim Senussi Order.
The Provinces of Libya were prescribed in 1934, during the last period of colonial Italian Libya, and continued through post-independence Libya until 1963 when the Governorates system was instituted.
The Italian colonizationof Libya began in 1911 and it lasted until 1943. The country, which was previously an Ottoman possession, was occupied by Italy in 1911 after the Italo-Turkish War, which resulted in the establishment of two colonies: Italian Tripolitania and Italian Cyrenaica. In 1934, the two colonies were merged into one colony which was named the colony of Italian Libya. In 1937, this colony was divided into four provinces, and in 1939, the coastal provinces became a part of metropolitan Italy as the Fourth Shore. The colonization lasted until Libya's occupation by Allied forces in 1943, but it was not until the 1947 Paris Peace Treaty that Italy officially renounced all of its claims to Libya's territory.
The Kingdom of Libya, known as the United Kingdom of Libya from 1951 to 1963, was a constitutional monarchy in North Africa that came into existence upon independence on 24 December 1951 and lasted until a bloodless coup d'état on 1 September 1969. The coup, led by Muammar Gaddafi, overthrew King Idris and established the Libyan Arab Republic.
The Senussi campaign took place in North Africa from November 1915 to February 1917, during the First World War. The campaign was fought by the Kingdom of Italy and the British Empire against the Senussi, a religious order of Arabic nomads in Libya and Egypt. The Senussi were courted by the Ottoman Empire and the German Empire. Recognising French and Italian threats, the Ottoman Sultan Abdulhamid II had twice sent his aide-de-camp Azmzade Sadik El Mueyyed to meet Sheikh Muhammed El Mehdi El Senussi to cultivate positive relations and counter the west European scramble for Africa. In the summer of 1915, the Ottomans persuaded the Grand Senussi Ahmed Sharif as-Senussi to declare jihad, attack British-occupied Egypt from the west and to encourage insurrection in Egypt to divert British forces.
