Basic facts about Libya:
— 1951: Libya wins independence after three decades of Italian colonial rule and eight years of U.N. trusteeship.
— 1969: Moammar Gadhafi, a 27-year-old army captain, leads a largely peaceful coup that overthrows the monarchy, quickly becoming Libya's undisputed ruler. He moves to establish a socialist system, including nationalizing businesses, and supports groups considered by the West to be terrorists.
— April 1986: U.S. jets bomb a Gadhafi compound in Tripoli after Libya is found responsible for a bomb blast at a Berlin discotheque frequented by U.S. troops. The U.S. airstrikes kill Gadhafi's adopted baby daughter.
— 1988: Suspected Libyan agents plant a bomb that blows up Pan Am Flight 103 over the Scottish town of Lockerbie, killing 270 people, mostly Americans. In the wake of the bombing, Libya becomes increasingly isolated, including the subject of U.N. sanctions.
— 2003: Libya accepts responsibility for the Lockerbie bombing and says it will end efforts to develop weapons of mass destruction. In following years, it makes progress toward normalizing relations with the West.
— January 2009: The U.S. and Libya exchange ambassadors for the first time in 35 years, after Libya pays compensation to the families of the Lockerbie victims.
— 2009: Gadhafi marks 40 years of rule with lavish celebrations. He is elected chairman of the African Union for one year.
