Osama bin Mohammed bin Awad bin Laden (10 March 1957 – 2 May 2011) was the founder and first general emir of al-Qaeda. Ideologically a pan-Islamist, Bin Laden participated in the Afghan mujahideen during the Soviet–Afghan War of the 1980s, and supported the Bosnian mujahideen during the Bosnian War of the 1990s. Opposed to American foreign policy in the Middle East, Bin Laden declared war on the United States in 1996 and supervised numerous terrorist attacks in various countries, including the September 11 attacks in 2001 in the U.S.
Born in Riyadh to the aristocratic bin Laden family, he studied at Saudi and foreign universities until 1979, when he joined the mujahideen fighting against the Soviet invasion of Afghanistan. In 1984, he co-founded Maktab al-Khidamat, which recruited foreign mujahideen into the war. As the Soviet war in Afghanistan came to an end, Bin Laden founded al-Qaeda in 1988 to carry out worldwide jihad. In the Gulf War, Bin Laden's offer of support to Saudi Arabia against Iraq was rejected by the Saudi royal family, which instead sought American aid.
