Education and political activism: 1950–1963

Gaddafi's earliest education was of a religious nature, imparted by a local Islamic teacher. Subsequently, moving to nearby Sirte to attend elementary school, he progressed through six grades in four years. Education in Libya was not free, but his father thought it would greatly benefit his son despite the financial strain. During the week Gaddafi slept in a mosque, and only at weekends and holidays walked 20 miles (32 km) to visit his parents. Even though Gaddafi's father was not educated, he made great sacrifices to send his son to school. As an impoverished Bedouin, he faced bullying and discrimination from his city-dwelling classmates. However, he had many Egyptian teachers who informed him of the dramatic events occurring in their homeland. From Sirte, he and his family moved to the market town of Sabha in Fezzan, south-central Libya, where his father worked as a caretaker for a tribal leader while Muammar attended secondary school, something neither parent had done. Gaddafi was popular at this school; some friends made there received significant jobs in his later administration, most notably his best friend, Abdul Salam Jalloud.

Many teachers at Sabha were Egyptian, and for the first time, Gaddafi had access to pan-Arab newspapers and radio broadcasts, especially the Cairo -based Voice of the Arabs. Growing up, Gaddafi witnessed significant events rock the Arab world, including the 1948 Arab–Israeli War, the Egyptian Revolution of 1952, the Suez Crisis of 1956, and the short-lived existence of the United Arab Republic (UAR) between 1958 and 1961. Gaddafi admired the political changes implemented in the Arab Republic of Egypt under his hero, President Gamal Abdel Nasser. Nasser argued for Arab nationalism; the rejection of Western colonialism, neo-colonialism, and Zionism; and a transition from capitalism to socialism. Gaddafi was influenced by Nasser's book, Philosophy of the Revolution, which outlined how to initiate a coup. One of Gaddafi's Egyptian teachers, Mahmoud Efay, was reportedly sympathetic towards the youth's political ideas, and advised him that a successful revolution would need the support of the army.

Gaddafi organized demonstrations and distributed posters criticizing the monarchy. In October 1961, he led a demonstration protesting against Syria's secession from the UAR and raised funds to send cables of support to Nasser. Twenty students were arrested as a result of the disorder. Gaddafi and his companions also broke windows in a local hotel that was accused of serving alcohol. To punish Gaddafi, the authorities expelled him and his family from Sabha. Gaddafi moved to Misrata, there attending Misrata Secondary School. Maintaining his interest in Arab nationalist activism, he refused to join any of the banned political parties active in the city—including the Arab Nationalist Movement, the Arab Socialist Ba'ath Party, and the Muslim Brotherhood —claiming that he rejected factionalism. He read voraciously on the subjects of Nasser and the French Revolution of 1789, as well as the works of the Syrian political theorist Michel Aflaq and biographies of Abraham Lincoln, Sun Yat-sen, and Mustafa Kemal Atatürk.
