Who was Abu Bakr al-Baghdadi?
Abu Bakr al-Baghdadi (1971–2019) was the leader of the Islamic State in Iraq and Syria (ISIS) from 2010 to 2019. After the U.S. invasion of Iraq in 2003, he participated in the insurgency against the U.S. occupation and was detained in Camp Bucca in 2004 before being released later that year. By 2010, he had risen to become the head of ISI, which later became ISIS. Baghdadi declared himself "caliph" of the group's self-proclaimed pan-Islamic state in June 2014 after ISIS captured Mosul. On October 26, 2019, Baghdadi killed himself as U.S. forces closed in on him in Idlib governorate, Syria.

What is ISIS?
ISIS, or the Islamic State in Iraq and Syria, is a transnational jihadist group with origins in the Iraq War of 2003–11. It grew out of an insurgency by Sunni Iraqis and formerly acted as an affiliate of al-Qaeda.
Under Abu Bakr al-Baghdadi, who became the leader of the organization in 2010, ISIS gained strength amidst regional instability, particularly the Syrian Civil War. In June 2014, after capturing Mosul, Iraq, ISIS declared the establishment of a caliphate with al-Baghdadi as its caliph. The group was responsible for numerous brutal attacks and widespread violence against civilians to enforce its hard-line interpretation of Islamic law. Al-Baghdadi killed himself in October 2019 as U.S. forces closed in on him in Syria.

How did Abu Bakr al-Baghdadi become the leader of ISIS?
Abu Bakr al-Baghdadi became the leader of the Islamic State of Iraq (ISI) in 2010, later known as ISIS. At the time Baghdadi took over, ISI was weak, but regional instability offered opportunities for the group to grow. The Syrian Civil War, which began in 2011, created a power vacuum in eastern Syria, which allowed ISI fighters to move freely between Iraq and Syria. The group gained Syrian recruits, drawn to their experience and fighters. In April 2013, Baghdadi declared his intention to merge the Nusrah Front with ISI under his leadership, but the merger was resisted. Capitalizing on its success, ISIS quickly pushed northward and in June captured Mosul, Iraq’s second largest city. Later that month ISIS designated Baghdadi “caliph” of its self-proclaimed pan-Islamic state.

What were some actions or decisions Abu Bakr al-Baghdadi made as the leader of ISIS?
As leader of the Islamic State in Iraq and Syria (ISIS), Abu Bakr al-Baghdadi, who took the helm in 2010, made several significant decisions. He announced the intention to merge the Nusrah Front with ISI in April 2013, but this was resisted. In January 2014, ISIS expelled the Nusrah Front from Al-Raqqah, Syria, using the city as its base. Capitalizing on regional instability, ISIS pushed northward, capturing Mosul, Iraq, in June 2014. Later that month, ISIS designated al-Baghdadi as "caliph" of its self-proclaimed pan-Islamic state. By mid-2015, however, ISIS appeared to be weakening. On the night of October 26–27, 2019, al-Baghdadi killed himself as U.S. forces closed in on him in Idlib governorate, Syria.

How did ISIS change under Abu Bakr al-Baghdadi's leadership?
Under Abu Bakr al-Baghdadi's leadership, ISIS evolved significantly from 2010 to 2019. When al-Baghdadi took over in 2010, the Islamic State of Iraq (ISI) was weak, but regional instability offered opportunities for growth. The Syrian Civil War created a power vacuum, enabling ISI fighters to move between Iraq and Syria, recruiting Syrian fighters.
In April 2013, al-Baghdadi sought to merge the Nusrah Front with ISI, but was resisted. Competition for recruits led to open fighting, and ISIS expelled the Nusrah Front from Al-Raqqah, Syria in January 2014, using the city as its base. Capitalizing on Sunni opposition to the Iraqi government, ISIS took control of Fallujah and then Mosul in June 2014. Later that month, ISIS declared al-Baghdadi the caliph of its self-proclaimed Islamic State. Though ISIS reached its peak by early 2015, controlling over 41,000 square miles in Iraq and Syria, ISIS began losing ground by mid-2015.

What happened to Abu Bakr al-Baghdadi and how did it affect ISIS?
Abu Bakr al-Baghdadi, the leader of the Islamic State in Iraq and Syria (ISIS) from 2010 to 2019, killed himself on October 26, 2019, as U.S. forces closed in on him in Syria.
Even though ISIS lost its territory by March 2019, thousands of its fighters and sympathizers remained at large. Attacks continued, increasing significantly in 2024 because regional conflict weakened the Syrian government, enabling an ISIS resurgence in the country.

Abu Bakr al-Baghdadi (born July 28, 1971, Arāḍī al-Jallām, Baghdād governorate [now in Ṣalāḥ al-Dīn governorate], Iraq—died October 26–27, 2019, Bārīshā, Idlib governorate, Syria) was the leader of the Islamic State in Iraq and Syria (ISIS) from 2010 to 2019.
The details of Baghdadi’s life remain uncertain or unknown. The anecdotes made public by ISIS paint an image of religious authority and piety, but many of the details have not been independently verified. His education included advanced study in Qurʾānic studies, and in 2007 he received a doctorate from Al-Nahrain University in Baghdad. His performance as a student is unclear, and he never became an accomplished figure among Islamic scholars.
After the U.S. invasion of Iraq in 2003 and the subsequent toppling of Saddam Hussein’s Baʿath Party regime, Baghdadi participated in the insurgency against the U.S. occupation and the interim Iraqi government. He was detained in a U.S. detention center, Camp Bucca, in February 2004, and, as a “civilian internee” of little concern, he was released in December that same year. (Contrary to reports that surfaced in 2014, the Pentagon has no record of detaining Baghdadi at any other time.) His early activities in the self-branded Islamic State of Iraq (ISI; until 2006 commonly known as Al-Qaeda in Iraq [AQI]) are not known to be significant, and his rise to leadership remains obscure. In 2010 he became the head of the organization.
ISI had become fairly weak and insignificant by the time Baghdadi took the helm, but the growing instability in the region created opportunities for ISI during the period of his leadership. The Syrian Civil War, which began in 2011, caused a power vacuum in eastern Syria, allowing ISI fighters to permeate the border and move freely between ungoverned portions of Iraq and Syria. The group gained Syrian recruits who were attracted by its organizational experience and its seasoned fighters. In April 2013 Baghdadi announced his intention to merge the Nusrah Front (Jabhat al-Nusrah)—another al-Qaeda affiliate in Syria and the precursor of Hayat Tahrir al-Sham—with ISI under his leadership. But the merger, dubbed by Baghdadi as the Islamic State in Iraq and Syria, was resisted by the Nusrah Front’s leader, Abu Mohammad al-Jolani (Golani). The competition for recruits led to open fighting between the al-Qaeda affiliates, and in January 2014 ISIS expelled the Nusrah Front from Al-Raqqah, Syria, and used the city as its exclusive territorial base.
Meanwhile, in Iraq the predominantly Shiʿi government became increasingly sectarian, stoking staunch opposition from Sunni populations. In December 2013 Iraqi security forces attempted to quell a protest movement centered in the city of Fallujah, but resistance led to riots and street battles. Local militias were soon joined by militants from ISIS, who took control of the city center in January 2014. Many Sunnis who had previously fought against the group, which they came to resent for its attempts to interfere in local society, now saw ISIS as a liberating force against an even more intrusive body: the Iraqi government. Capitalizing on its success, ISIS quickly pushed northward and in June captured Mosul, Iraq’s second largest city. Later that month ISIS designated Baghdadi “caliph” of its self-proclaimed pan-Islamic state. Days later he made his first public appearance at the weekly jumʿah prayers in Mosul’s Great Mosque.
Baghdadi made few subsequent appearances, however, and his public communications were directed primarily through audio recording. His reclusiveness led to occasional rumors of his death or injury as Iraqi, Syrian, and Kurdish forces advanced on ISIS, but a video recording released in April 2019 demonstrated his survival even after Iraq and Syria declared ISIS defeated in 2017. On the night of October 26–27, 2019, Baghdadi killed himself by self-detonation as U.S. forces closed in on him in Idlib governorate, Syria.
