History & Founding
Al-Qaeda was formally established in 1988 in Peshawar, Pakistan, by Osama bin Laden — the Saudi-born son of a billionaire construction magnate — and his associate Abdullah Azzam, during the final stages of the Soviet-Afghan War. Bin Laden had arrived in Afghanistan in 1980 to support the mujahideen resistance against Soviet occupation, using his personal wealth and family connections to fund fighters and infrastructure. The CIA and Saudi intelligence also channelled significant support to the broader mujahideen effort, though direct operational links to Al-Qaeda's formation remain disputed by historians.
Following the Soviet withdrawal in 1989, bin Laden returned to Saudi Arabia — only to be radicalised further by the 1990 stationing of US troops on Saudi soil ahead of the Gulf War. He considered the presence of non-Muslim military forces on the Arabian Peninsula — home to Mecca and Medina, Islam's two holiest sites — an intolerable religious desecration. Expelled from Saudi Arabia in 1991, he relocated to Sudan and then Afghanistan, where the Taliban provided him sanctuary from 1996 onward.
In August 1996, bin Laden issued his first formal declaration of war against the United States, and in February 1998 published a fatwa — signed jointly with Ayman al-Zawahiri of Egyptian Islamic Jihad — declaring it a religious duty for Muslims to kill Americans and their allies, civilian and military, anywhere in the world.
"The ruling to kill the Americans and their allies — civilians and military — is an individual duty for every Muslim who can do it in any country in which it is possible to do it."
Osama bin Laden & Ayman al-Zawahiri, fatwa, February 1998The 1998 East Africa embassy bombings — simultaneous truck bomb attacks on US embassies in Nairobi, Kenya, and Dar es Salaam, Tanzania, killing 224 people and wounding over 4,500 — announced Al-Qaeda's arrival as a global terrorist threat. The USS Cole bombing in 2000 (17 US sailors killed) followed. Then came September 11, 2001.
The 9/11 attacks — carried out by 19 Al-Qaeda operatives who hijacked four commercial airliners, crashing two into the World Trade Centre, one into the Pentagon, and one into a Pennsylvania field after passengers attempted to overpower the hijackers — killed 2,977 people and triggered the US-led invasion of Afghanistan and the global War on Terror. Bin Laden was ultimately tracked to a compound in Abbottabad, Pakistan, and killed by US Navy SEALs on 2 May 2011.

2022–PresentSaif al-Adel assumed to lead from Iran. Al-Qaeda affiliates remain most active jihadist forces across the Sahel and Horn of Africa, with JNIM and Al-Shabaab controlling significant territory.
Ideology & Strategy
Al-Qaeda's ideology is rooted in Salafi-jihadism — a fusion of the Salafi movement's literalist, puritanical interpretation of Islam with the concept of armed jihad as a personal religious obligation. Its intellectual foundations draw directly from Sayyid Qutb's Muslim Brotherhood writings, particularly the concept that contemporary Muslim societies have fallen into a state of pre-Islamic ignorance (jahiliyyah) and must be violently purified.
Al-Qaeda's strategic doctrine, as articulated by bin Laden and al-Zawahiri, targets the "far enemy" — the United States and its Western allies — on the theory that destroying Western support for Middle Eastern governments will cause those governments to collapse, enabling Islamic states to be established in their place. This distinguishes Al-Qaeda from groups like ISIS, which focused primarily on immediate territorial conquest.
Al-Qaeda views the entire world as divided into two camps: the House of Islam and the House of War. All non-Muslims and Muslims who collaborate with non-Muslim governments are legitimate targets. The organisation explicitly endorses mass civilian casualties as a legitimate tactic, arguing that Western citizens bear collective responsibility for their governments' actions in Muslim lands.
"We have the right to kill four million Americans — two million of them children — and to exile twice as many and wound and cripple hundreds of thousands."
Suleiman Abu Ghaith, Al-Qaeda spokesman, 2002 — cited in US federal court proceedingsUnlike ISIS's apocalyptic urgency, Al-Qaeda has historically taken a longer strategic view — prioritising the gradual weakening of Western will and the building of a global jihadist movement over immediate territorial gains. This patient, decentralised approach has proved remarkably resilient: despite losing its Afghan sanctuary, its founder, and most of its senior leadership to drone strikes, Al-Qaeda's affiliate network has expanded its territorial footprint significantly since 2011.
Affiliates & Regional Commands
Al-Qaeda operates through a franchise model of formally affiliated regional organisations, each with significant operational autonomy while maintaining ideological alignment with the core organisation. Since 2011, these affiliates have dramatically expanded Al-Qaeda's geographic footprint.
Affected Populations & IFC Desks
Al-Qaeda's global affiliate network touches every major IFC regional desk. Its long-term strategy of targeting secular governments and Western-aligned states has devastated communities across Africa, the Middle East, and Asia.
