On September 1, 1969, in a daring coup d'état, a group of about seventy young army officers and enlisted men, mostly assigned to the Signal Corps, seized control of the government and in a stroke abolished the Libyan monarchy. The coup was launched at Benghazi, and within two hours the takeover was completed. Army units quickly rallied in support of the coup, and within a few days firmly established military control in Tripoli and elsewhere throughout the country. Popular reception of the coup, especially by younger people in the urban areas, was enthusiastic. Fears of resistance in Cyrenaica and Fezzan proved unfounded. No deaths or violent incidents related to the coup were reported.
The Free Officers Movement, which claimed credit for carrying out the coup, was headed by a twelve-member directorate that designated itself the Revolutionary Command Council (RCC). This body constituted the Libyan government after the coup. In its initial proclamation on September 1, the RCC declared the country to be a free and sovereign state called the Libyan Arab Republic, which would proceed, with the help of God, "in the path of freedom, unity, and social justice, guaranteeing the right of equality to its citizens, and opening before them the doors of honorable work." The rule of the Turks and Italians and the "reactionary" regime just overthrown were characterized as belonging to "dark ages," from which the Libyan people were called to move forward as "free brothers" to a new age of prosperity, equality, and honor.
The RCC advised diplomatic representatives in Libya that the revolutionary changes had not been directed from outside the country, that existing treaties and agreements would remain in effect, and that foreign lives and property would be protected. Diplomatic recognition of the new regime came quickly from countries throughout the world. United States recognition was officially extended on September 6.
In view of the lack of internal resistance, it appeared that the chief danger to the new regime lay in the possibility of a reaction inspired by the absent King Idris or his designated heir, Hasan ar Rida, who had been taken into custody at the time of the coup along with other senior civil and military officials of the royal government.
Within days of the coup, however, Hasan publicly renounced all rights to the throne, stated his support for the new regime, and called on the people to accept it without violence. Idris, in an exchange of messages with the RCC through Egypt's President Nasser, dissociated himself from reported attempts to secure British intervention and disclaimed any intention of coming back to Libya. In return, he was assured by the RCC of the safety of his family still in the country. At his own request and with Nasser's approval, Idris took up residence once again in Egypt, where he had spent his first exile and where he remained until his death in 1983.
On September 7, 1969, the RCC announced that it had appointed a cabinet to conduct the government of the new republic. An American-educated technician, Mahmud Sulayman al Maghrabi, who had been imprisoned since 1967 for his political activities, was designated prime minister. He presided over the eight-member Council of Ministers, of whom six, like Maghrabi, were civilians and two--Adam Said Hawwaz and Musa Ahmad--were military officers. Neither of the officers was a member of the RCC. The Council of Ministers was instructed to "implement the state's general policy as drawn up by the RCC," leaving no doubt where ultimate authority rested. The next day the RCC decided to promote Captain Muammar al-Qaddafi to colonel and to appoint him commander in chief of the Libyan Armed Forces. Although RCC spokesmen declined until January 1970 to reveal any other names of RCC members, it was apparent from that date onward that the head of the RCC and new de facto head of state was the ascetic, deeply religious, twenty-seven-year-old Colonel Qaddafi.
