Libyan Army (1951–2011) in the context of "1969 Libyan revolution"

Muammar Gaddafi became the de facto leader of Libya on 1 September 1969 after leading a group of Libyan Army officers against King Idris I in a bloodless coup d'état. When Idris was in Turkey for medical treatment, the Revolutionary Command Council (RCC) headed by Gaddafi abolished the monarchy and the constitution and established the Libyan Arab Republic, with the motto "Unity, Freedom, Socialism". The name of Libya was changed several times during Gaddafi's tenure as leader. From 1969 to 1977, the name was the Libyan Arab Republic. In 1977, the name was changed to Socialist People's Libyan Arab Jamahiriya. Jamahiriya was a term coined by Gaddafi, usually translated as "state of the masses". The country was renamed again in 1986 as the Great Socialist People's Libyan Arab Jamahiriya, after the United States bombing that year.

After coming to power, with the oil price rise of the 1970s and consequential rise of the Libyan economy, the RCC government initiated a process of directing funds toward providing education, health care and housing for all. Public education in the country became free and primary education compulsory for both sexes. However, the quality of the education system was far below many other Arab states, even those with much less oil wealth, with 2 hours a week being dedicated to his Green Book. It was also illegal to learn a second language for more than a decade. There were instances of revolt, like the 1976 Libyan protests. There was some students who even faced public execution in the university, witnessed by many other students and broadcast on Libyan state television, such as the Execution of Al-Sadek Hamed Al-Shuwehdy. Medical care became available to the public at no cost, but the quality was far below those of some of its neighbours (Tunisia, Egypt & Malta) which prompted many Libyans to get medical treatments in those countries. Providing housing for all was a task the RCC government was unable to complete. Under Gaddafi, per capita income in the country rose to more than US$11,000 in nominal terms, and to over US$30,000 in PPP terms, the 5th highest in Africa. The increase in prosperity was accompanied by a foreign policy hostile to the other Arab states of the region, an anti-West foreign policy, and increased domestic political repression.

The 1969 Libyan revolution, also known as the al-Fateh Revolution or 1 September Revolution, was a coup d'état and revolution carried out by the Free Officers Movement, a group of Arab nationalist and Nasserist officers in the Libyan Army, which overthrew the Senussi monarchy of King Idris I and resulted in the formation of the Libyan Arab Republic. The Free Officers Movement was led by Colonel Muammar Gaddafi.

The government of Idris was increasingly unpopular by the late 1960s due to internal mismanagement, and the rise of Arab nationalist sentiment further weakened his regime. On 1 September 1969, while Idris was in Turkey, a group of Libyan Army officers under the leadership of Gaddafi launched a coup from Benghazi and quickly established control over the country. The coup was bloodless and received enthusiastic support from the public. Crown prince Hasan as-Senussi relinquished his claim to the throne, and Libya was declared a free and sovereign republic by the Revolutionary Command Council (RCC). Gaddafi, in his capacity as RCC chairman, became the de facto head of state.

The Free Officers movement (Arabic: حركة الضباط الأحرار) was a group of Arab nationalist and Nasserist officers in the Libyan Army that planned and carried out the 1969 Libyan revolution, which overthrew the Senussi monarchy of King Idris I, ending the Libyan monarchy. It was led by a twelve-member cabinet known as the Revolutionary Command Council, whose chairman was Muammar Gaddafi, which came to govern the Libyan Arab Republic.
