How did King Idris I become Libya’s first king?

King Idris I became the first king of Libya following the country's transition to independence after World War II. After years of international deliberation regarding the future of the region, the United Nations General Assembly resolved in November 1949 that representatives from the three provinces of Cyrenaica, Fezzan, and Tripolitania should determine the nation's future.12

A national assembly was subsequently formed, which established a constitutional monarchy and offered the throne to Idris, the head of the Sanūsiyyah order. He was chosen as king by this assembly in 1950, and he officially declared Libya an independent kingdom on December 24, 1951.12
