Al-Qaeda in Iraq in the context of "Bay'ah"

Ahmed Hussein al-Sharaa (born 29 October 1982), also known by his nom de guerre Abu Mohammad al-Julani, is a Syrian politician, revolutionary, and former rebel commander who has served as the president of Syria since 2025. He previously served as the emir of Hay'at Tahrir al-Sham (HTS) from 2017 to 2025 and was Syria's de facto leader from December 2024 until his appointment as president.

Born in Riyadh, Saudi Arabia, to a Syrian Sunni Muslim family from Daraa and the Golan Heights, he grew up in Syria's capital, Damascus. Al-Sharaa joined al-Qaeda in Iraq shortly before the 2003 invasion of Iraq and fought for three years in the Iraqi insurgency. American forces captured and imprisoned him from 2006 to 2011. His release coincided with the Syrian Revolution against the Ba'athist dictatorship of Bashar al-Assad. Al-Sharaa created the al-Nusra Front in 2012 with the support of al-Qaeda to topple the Assad regime in the Syrian civil war. As emir of the al-Nusra Front, al-Sharaa built a stronghold in the northwestern Idlib Governorate. He resisted Abu Bakr al-Baghdadi's attempts to merge al-Nusra Front with the Islamic State, leading to armed conflict between the two groups. In 2016, al-Sharaa cut al-Nusra's ties with al-Qaeda and launched a crackdown on its loyalists. Since breaking with al-Qaeda, he has sought international legitimacy by presenting a more moderate view of himself, renouncing transnational jihadism against Western nations, and focusing on governance in Syria while vowing to protect Syria's minorities.

The Islamic State (IS), also known as the Islamic State of Iraq and the Levant (ISIL), the Islamic State of Iraq and Syria (ISIS) and the Daesh, is a transnational Salafi jihadist militant organisation and an unrecognised quasi-state. IS occupied significant territory in Iraq and Syria in 2013, but lost most of it between 2017 and 2019. In 2014, the group proclaimed itself to be a worldwide caliphate, and claimed religious and political authority over all Muslims worldwide, a claim not accepted by the vast majority of Muslims. It is designated as a terrorist organisation by the United Nations and many countries around the world, including Muslim countries.

By the end of 2015, its self-declared caliphate ruled an area with a population of about 12 million, where they enforced their extremist interpretation of Islamic law, managed an annual budget exceeding US$1 billion, and commanded more than 30,000 fighters. After a grinding conflict with American, Iraqi, and Kurdish forces, IS lost control of all its Middle Eastern territories by 2019, subsequently reverting to insurgency from remote hideouts while continuing its propaganda efforts. These efforts have garnered a significant following in northern and Sahelian Africa, where IS still controls a significant territory. Originating in the Jaish al-Ta'ifa al-Mansurah founded by Abu Omar al-Baghdadi in 2004, the organisation (primarily under the Islamic State of Iraq name) affiliated itself with al-Qaeda in Iraq and fought alongside them during the 2003–2006 phase of the Iraqi insurgency. The group later changed their name to Islamic State of Iraq and Levant for about a year, before declaring itself to be a worldwide caliphate, called simply the Islamic State (الدولة الإسلامية, ad-Dawlah al-Islāmiyya).

The Iraqi civil war was a short armed conflict from 2006 to 2008 between various sectarian Shia and Sunni armed groups, such as the Islamic State of Iraq and the Mahdi Army, in addition to the Iraqi government alongside American-led coalition forces. In February 2006, the insurgency against the coalition and government escalated into a sectarian civil war after the bombing of Al-Askari Shrine, considered a holy site in Twelver Shi'ism. US President George W. Bush and Iraqi officials accused Al-Qaeda in Iraq (AQI) of orchestrating the bombing. AQI publicly denied any links. The incident set off a wave of attacks on Sunni civilians by Shia militants, followed by attacks on Shia civilians by Sunni militants.

The UN Secretary General stated in September 2006 that if patterns of discord and violence continued, the Iraqi state was in danger of breaking up. On 10 January 2007, Bush said that "80% of Iraq's sectarian violence occurs within 30 miles (48 km) of the capital. This violence is splitting Baghdad into sectarian enclaves, and shakes the confidence of all Iraqis." By late 2007, the National Intelligence Estimate described the conflict as having elements of a civil war. In 2008, during the Sunni Awakening and the U.S. troop surge, violence declined dramatically. However, an insurgency by ISI continued to plague Iraq following the U.S. withdrawal in late 2011. In June 2014, the Islamic State of Iraq and the Levant, the successor to Islamic State of Iraq, launched a major military offensive against the Iraq government and declared a self-proclaimed worldwide Islamic caliphate. This led to another full-scale war from 2013 to 2017, in which the government declared victory.

Ibrahim Awwad Ibrahim Ali al-Badri (28 July 1971 – 27 October 2019), commonly known by his nom de guerre Abu Bakr al-Baghdadi, was an Iraqi militant leader and former teacher who was the founder and first leader of the Islamic State (IS), who proclaimed himself caliph in 2014 and stayed in power until his suicide in an American operation in 2019.

Baghdadi was born in Samarra and obtained graduate degrees in Islamic theology in the late 1990s and 2000s. According to supporters, he obtained a PhD at the Islamic University of Baghdad. Following the American invasion of Iraq in March 2003, Baghdadi led the "Jama'at Jaysh Ahl al-Sunna wal-Jama'ah" insurgent group in Iraq and was detained with al-Qaeda commanders at the American Camp Bucca in 2004. His group joined the Mujahideen Shura Council (MSC) coalition in 2006 and fought alongside al-Qaeda in Iraq. Upon the dissolution of the MSC in October 2006, Baghdadi became a leading member of the newly established Islamic State of Iraq organization, and rose through the group's ranks until he was appointed its emir, the highest leader, in 2010. In March 2013, the group renamed itself as the "Islamic State of Iraq and Levant" (ISIL), announcing its intention to expand into Syria and forcibly assimilate the Al-Nusra Front, leading to a conflict with al-Qaeda's general command. In June 2014, the group once again re-designated itself as the "Islamic State", and declared itself to be a caliphate. Baghdadi was chosen caliph of the Islamic State by a "Shura Council", which represented those members of the Islamic State allegedly qualified to elect a caliph.

Jaish al-Ta'ifa al-Mansurah (Arabic: جيش الطائفة المنصورة, romanized: Army of the Victorious Sect) was an Iraqi Salafi-jihadist insurgent group that fought against US troops and their local allies during the Iraq War. In 2006 the group aligned itself with al-Qaeda and helped establish the Mujahideen Shura Council.
