Osama bin Laden was a Saudi citizen and co-founder and leader of al-Qaeda, notorious for orchestrating the September 11, 2001, attacks that killed nearly 3,000 people. Throughout his three-decade-long jihadist career, bin Laden oversaw the planning of numerous largescale terrorist attacks, established a network of al-Qaeda-linked businesses and operatives, and united terrorist groups from the Middle East, Africa, Eastern Europe, and Asia. Between 1996 and 2001, he lived in Afghanistan under the protection of the ruling Taliban and its leader Mullah Mohammed Omar. Bin Laden was killed on May 2, 2011, in a shootout with U.S. Navy SEALS at a compound in Abbottabad, Pakistan. Bin Laden was succeeded as al-Qaeda's emir by Ayman al-Zawahiri.
Born in Riyadh, Saudi Arabia, in 1957, Osama bin Laden was the 17th of 54 children fathered by Saudi billionaire Mohammed bin Laden. The elder bin Laden, an immigrant from Yemen, was the head of a successful construction firm—building many of the palaces and major roads in the kingdom as well as renovating Jerusalem’s Al Aqsa Mosque. Osama’s mother, Hamida al-Attas, came from a prominent Syrian Alawite family and was Mohammed bin Laden’s tenth wife. Osama’s parents divorced soon after he was born, and his father died in a plane crash when he was five years old. Nevertheless, Osama would later work for and inherit millions from his father’s business empire.
In high school bin Laden joined the Saudi branch of the Muslim Brotherhood and read the extremist texts of influential Brotherhood ideologue Sayyid Qutb. Bin Laden’s friend at the time, Jamal Khalifa, later said that Qutb “was the one who most affected [his and bin Laden’s] generation.” In his books, Qutb called for an Islamic “vanguard” to take up jihad against secular governments and eventually resurrect the caliphate. Qutb also re-popularized the Islamic concept of takfir, which permits the labeling of fellow Muslims as apostates, thus justifying their persecution and murder.
In 1974, bin Laden—then a deeply pious 18-year-old—married his 14-year-old Syrian cousin. Bin Laden would go on to marry two more women and father at least 23 children. Between 1976 and 1979, bin Laden studied economics at the King Abdul Aziz University in Jeddah. There, he formed a religious charity on campus, whose members “devoted a lot of time to interpreting the Quran and jihad,” according to bin Laden’s own account. It was also at that university that bin Laden met Abdullah Azzam, a renowned Palestinian scholar and a professor at the school. Azzam, often referred to as the father of modern jihad, would serve as a spiritual mentor to bin Laden and eventually become a co-founder of al-Qaeda.
Bin Laden reportedly traveled to the Afghanistan-Pakistan border within two weeks of the Soviet invasion of Afghanistan in December 1979. Bin Laden acted as a visiting envoy, meeting various militant leaders and devising ways to raise funds for the mujahideen (“holy warriors”). In the early-mid 1980s, he traveled back and forth to Saudi Arabia, where he implored wealthy family members to financially support the Afghan jihad. Bin Laden also brought construction machinery and Arab recruits into Afghanistan, and provided the fighters with logistical and humanitarian aid. Bin Laden’s former professor, Abdullah Azzam, arrived in Peshawar in late 1981, and the two men worked closely to recruit, train, and equip Arab fighters for the jihad.
In September 1984, bin Laden and Azzam decided to create a formal role for Arabs and other foreign (including Western) fighters in Afghanistan. The pair soon established the Services Bureau (Makhtab al-Khadamat)—an office, printing center, funds repository, and hostel for foreign mujahideen. Bin Laden also began to offer plane tickets, residences, and living expenses for the men, and by 1986 was believed to be paying $25,000 per month to subsidize the fighters.
In 1987, bin Laden met Ayman al-Zawahiri for the first time, in Pakistan. At the time, Zawahiri, an Egyptian doctor, was a key leader of Egyptian Islamic Jihad (EIJ)—a jihadist group responsible for the 1981 assassination of Egyptian President Anwar Sadat.
Bin Laden and Zawahiri quickly developed a close working relationship, and co-founded al-Qaeda (“the base”) in August 1988 alongside several other Islamist operatives, including Azzam. The secretary at the meeting noted that “al-Qaeda is basically an organized Islamic faction, its goal is to lift the word of God, to make His religion victorious.”
Within a year, however, disagreements arose between bin Laden and Azzam on al-Qaeda’s trajectory. While Azzam envisioned bringing the fight to Israel after Afghanistan, bin Laden preferred to prioritize targeting of the United States and Arab regimes such as the Saudi government. The disagreement ended when Azzam was killed in Peshawar on November 24, 1989. Zawahiri continued to direct EIJ until it finally merged with al-Qaeda in 2001.
After the Soviet withdrawal from Afghanistan in February 1989, bin Laden returned to Saudi Arabia emboldened by the perceived triumph of the mujahideen over the Soviets. While working at his father’s construction firm in Saudi Arabia, bin Laden was approached about moving his nascent al-Qaeda to Sudan by Hassan al-Turabi—the then-secretary general of the Sudanese Muslim Brotherhood. Turabi proposed allowing bin Laden use Sudan as al-Qaeda’s base in exchange for the building of roads and support in the ongoing war against Christian separatists in Southern Sudan. Bin Laden would not relocate to Sudan until late 1991.
In August 1990, as U.S. forces arrived in Saudi Arabia to prepare for the first Gulf War, bin Laden urged Saudi King Fahd to expel the Americans and instead allow the veterans of the Afghan war to defend the Arabian Peninsula. King Fahd declined bin Laden’s offer in favor of U.S. and allied forces. Enraged, bin Laden began to publicly rebuke the monarchy for its alliance with the United States, prompting Saudi Arabia to expel him in April 1991. Bin Laden fled to Afghanistan, and then accepted Sudanese leader Hassan al-Turabi’s offer—arriving in Sudan by 1992. There, he established legitimate businesses and began to build out the al-Qaeda network.
The first attack orchestrated by bin Laden and his associates occurred on December 19, 1992, when a bomb exploded in a hotel room in Aden, Yemen, killing two Australian tourists. Bin Laden had intended for the explosion to kill a unit of U.S. soldiers, but those troops had already left the premises. Attacks perpetrated by al-Qaeda operatives and like-minded jihadist increased in the following years. On February 26, 1993, Ramzi Yousef—a Pakistani terrorist not directly linked to al-Qaeda—carried out the Word Trade Center bombing, killing six people and injuring over 1,000 others. While bin Laden praised Yousef’s bombing, he is not believed to have played a role in the attack.
In April 1994, the Saudi government revoked bin Laden’s citizenship and froze his assets. Undeterred, bin Laden continued to grow his operations, establishing training camps for foreign fighters in Yemen near the Saudi border, according to U.S. intelligence sources. Meanwhile, the United States and Saudi Arabia began to pressure Sudan to expel bin Laden, citing his danger to the international community. In May 1996, Turabi reportedly gave bin Laden the choice to stay in Sudan and keep his operations quiet, or to leave the country altogether. Bin Laden opted to relocate his growing jihadist movement, and moved to Afghanistan shortly thereafter.
The Taliban controlled much of Afghanistan by the time bin Laden arrived. The group’s leader, Mullah Omar, allowed bin Laden to settle his family and operatives in the eastern city of Jalalabad. Bin Laden would later pledge allegiance to Mullah Omar in late August or early September 1998, forming a bond between the groups that persists to this day.
Bin Laden issued his first fatwa soon after arriving in Afghanistan. The statement, titled “Declaration of War Against the Americans Who Occupy the Land of the Two Holy Mosques,” was published by London’s Al Quds al Arabi newspaper on August 23, 1996. In it, bin Laden called on Muslims to force the U.S. military out of the Arabian Peninsula; dethrone the Saudi government; punish the U.S. and its allies for their “Crusade” against Islam; and liberate Muslim holy sites. Soon after the fatwa’s publication, bin Laden was visited by Khalid Sheikh Mohammed (KSM)—the uncle of World Trade Center bomber Ramzi Yousef. KSM appealed to bin Laden for funds and material to carry out a largescale attack in the United States. Bin Laden agreed to front the funds and asked KSM to join al-Qaeda, though KSM politely declined, deciding to operate independently.
Bin Laden would continue to issue fatwas and orchestrate largescale attacks against U.S. targets. In February 1998, he released his second fatwa—“Declaration of the World Islamic Front for Jihad against the Jews and the Crusaders”—in which he declared it a duty for Muslims to carry out jihad against Islam’s enemies and to expel Americans from the Gulf region. That August, al-Qaeda carried out its then-largest attack when operatives targeted the U.S. embassies in Nairobi, Kenya, and Dar es Salaam, Tanzania. The explosions in Nairobi killed 213 people—nearly all Kenyans and 12 Americans—and injured approximately 5,000 others. In Dar es Salaam, the bombs killed 11 people, none of them Americans. Three months later, in November 1998, bin Laden was indicted by a U.S. Federal Grand Jury in New York for engaging in a long-term conspiracy to attack U.S. facilities overseas and to kill American citizens. At around the same time he was indicted in New York, bin Laden met with KSM in Pakistan and officially approved his plot to weaponize airplanes and crash them into buildings in the United States. The 9/11 plot had begun to take form.
In November 1999, bin Laden received four visitors—Mohamed Atta, Marwan al Shehhi, Ziad Jarrah, and Ramzi bin al-Shibh. The men were members of an al-Qaeda cell in Hamburg, Germany, and were eager to partake in a terrorist attack against the United States. After swearing fealty to bin Laden, the men were instructed to enroll in flight training schools in the West. Bin Laden selected Atta to lead the cell, and revealed to him al-Qaeda’s top targets in the United States: the World Trade Center, the Pentagon, and the U.S. Capitol. Atta, Shehhi, and Jarrah would become hijacker-pilots in the 9/11 attacks, whereas Shibh would serve as a key facilitator in the attacks. Shibh is currently held by the United States as an enemy combatant at Guantanamo Bay, Cuba.
On October 12, 2000, in al-Qaeda’s last largescale attack before 9/11, two al-Qaeda suicide bombers steered a small boat laden with 400 to 700 pounds of explosives into the port side of the USS Cole while it refueled in Aden, Yemen. The explosion killed 17 U.S. sailors. The attack was masterminded by al-Qaeda operative Abd Rahim al-Nashiri upon instructions from bin Laden to target U.S. warships in Yemen’s southern port of Aden.
On September 11, 2001, 19 al-Qaeda operatives hijacked U.S. commercial airliners and flew them into the World Trade Center in New York and the Pentagon in Washington, D.C. A fourth hijacked airplane crashed in a field in rural Pennsylvania. Nearly 3,000 civilians were killed and thousands more injured. Within weeks, the U.S. launched military operations against al-Qaeda’s suspected safe havens in Afghanistan. That December, bin Laden is believed to have escaped U.S. bombing in Afghanistan’s Tora Bora Mountains and fled to Pakistan.
Bin Laden did not claim responsibility for the 9/11 attacks until October 2004, when he appeared in a video released by Al Jazeera. “We should destroy towers in America [because] we are a free people…and we want to regain the freedom of our nation,” bin Laden reasoned. The al-Qaeda leader further said that America might avoid another 9/11-style attack if it stopped compromising the “security” of Muslims, warning, “As you undermine our security we undermine yours.”
Bin Laden is believed to have settled in a compound in Abbottabad during the 2000s, though there is little publically available information on his whereabouts during this time. In 2009, the U.S. government announced that the al-Qaeda leader was most likely living on the Afghanistan-Pakistan border, but conceded that it had a “lack of intelligence” regarding his exact location. Living as an elusive fugitive, bin Laden was still able to release videos threatening the West and claim responsibility for al-Qaeda-linked attacks. In January 2010, bin Laden claimed responsibility for the failed bombing of a civilian airliner over Detroit, Michigan, on December 25, 2009. Perpetrated by “underwear bomber” Umar Farouk Abdulmutallab, the attack had been planned by al-Qaeda in the Arabian Peninsula (AQAP) cleric Anwar al-Awlaki.
In the early morning of May 2, 2011, a small team of U.S. Navy SEALS entered the Abbottabad compound where bin Laden was living and killed the 54-year-old al-Qaeda leader in a shootout. His body was transported to the U.S. aircraft carrier the USS Carl Vinson and given an Islamic burial at sea within 24 hours. In a televised statement on the night of May 2, President Barack Obama referred to bin Laden as al-Qaeda’s “leader and symbol” and warned that bin Laden’s death did “not mark the end of our effort. There’s no doubt that al-Qaeda will continue to pursue attacks against us.”
Bin Laden’s burial at sea took place within 24 hours of his death with proper religious rites, in accordance with Islamic law. Some Islamic scholars have argued there was no reason to give bin Laden a burial at sea instead of turning the body over to family or even his supporters for a proper burial. Dubai’s grand mufti Mohammed al-Qubaisi said at the time a sea burial was inappropriate and Islamic law required digging a simple grave if nobody was available to take custody of the body. U.S. officials, however, said there was not enough time to negotiate with other countries to take custody of the body. They further said the burial at sea took place to avoid bin Laden’s grave becoming a shrine.
Ayman al-Zawahiri, previously al-Qaeda’s second-in-command, was elevated to leader of the international terror group six weeks after bin Laden’s death. Zawahiri vowed to continue waging jihad against “crusader America and its servant Israel, and whoever supports them.” Bin Laden’s son Hamza bin laden was a key al-Qaeda operative being groomed for a senior leadership role prior to his own death in a 2019 U.S. counterterrorism operation in the Afghanistan-Pakistan region. Zawahiri reportedly died in November 2020 from asthma, but his death remains unconfirmed by al-Qaeda.
