Muammar al-Qaddafi, the young Libyan army captain who deposed King Idris in September 1969, is proclaimed premier of Libya by the so-called General People’s Congress.

Born in a tent in the Libyan desert, Qaddafi was the son of a Bedouin farmer. He attended university and the Libyan military academy and steadily rose in the ranks of the Libyan army. An ardent Arab nationalist, he plotted with a group of fellow officers to overthrow the Libyan monarchy, which they accomplished on September 1, 1969.

Blending Islamic orthodoxy, revolutionary socialism, and Arab nationalism, Qaddafi established a fervently anti-Western dictatorship. In 1970, he removed U.S. and British military bases and expelled Italian and Jewish Libyans. In 1973, he nationalized foreign-owned oil fields. He reinstated traditional Islamic laws, such as prohibition of alcoholic beverages and gambling, but liberated women and launched social programs that improved the standard of living in Libya. As part of his stated ambition to unite the Arab world, he sought closer relations with his Arab neighbors, especially Egypt. However, when Egypt and then other Arab nations began a peace process with Israel, Libya was increasingly isolated.

Qaddafi’s government financed a wide variety of terrorist groups worldwide, from Palestinian guerrillas and Philippine Muslim rebels to the Irish Republican Army. During the 1980s, the West blamed him for numerous terrorist attacks in Europe, and in April 1986 U.S. war planes bombed Tripoli in retaliation for a bombing of a West German dance hall. Qaddafi was reportedly injured and his infant daughter killed in the U.S. attack.

In the late 1990s, Qaddafi sought to lead Libya out of its long international isolation by turning over to the West two suspects wanted for the 1988 explosion of an airliner over Lockerbie, Scotland. In response, Europe lifted sanctions against Libya. After years of rejection in the Arab world, Qaddafi also sought to forge stronger relations with non-Islamic African nations such as South Africa, remodeling himself as an elder African statesman.

Qaddafi surprised many around the world when he became one of the first Muslim heads of state to denounce al-Qaida after the attacks of September 11, 2001. The next year, he offered a public apology for the Lockerbie bombing, later agreeing to pay nearly $3 billion in compensation to the victims’ families. In 2003, he gained favor with the administration of George W. Bush when he announced the existence of a program to build weapons of mass destruction in Libya and that he would allow an international agency to inspect and dismantle them. Though some in the U.S. government pointed to this as a direct and positive consequence of the ongoing war in Iraq, others pointed out that Qaddafi had essentially been making the same offer since 1999, but had been ignored. In 2004, U.K. Prime Minister Tony Blair visited Libya, one of the first western heads of state to do so in recent memory; he praised Libya during the visit as a strong ally in the international war on terror.

In February 2011, as unrest spread through much of the Arab world, massive political protests against the Qaddafi regime sparked a civil war between revolutionaries and loyalists. In March, an international coalition began conducting airstrikes against Qaddafi strongholds under the auspices of a U.N. Security Council resolution. On October 20, Libya’s interim government announced that Qaddafi had died after being captured near his hometown of Sirte.
