Osama bin Laden founded al-Qaeda during the latter stages of the Soviet-Afghan War with the goal of waging global jihad. Since its founding in 1988, al-Qaeda has played a role in innumerable terrorist attacks, and is most notoriously responsible for the multiple attacks on the United States on September 11, 2001. The 9/11 terror attacks—the deadliest ever on American soil—left nearly 3,000 people dead and provoked the United States to wage war against al-Qaeda in the group’s home bases in Afghanistan, Pakistan, and other sanctuaries worldwide. Since then, the group has established five major regional affiliates pledging their official allegiance to al-Qaeda: in the Arabian Peninsula, North Africa, East Africa, Syria, and the Indian subcontinent.
