The Islamic State (IS), also known as the Islamic State of Iraq and the Levant (ISIL), the Islamic State of Iraq and Syria (ISIS), the Islamic State of Iraq and al-Sham (ISIS) and by its Arabic acronym Daesh, is a transnational Salafi jihadist group and an unrecognised quasi-state.
Ibrahim Awad Ibrahim Ali al-Badri, commonly known by his nom de guerreAbu Bakr al-Baghdadi, was an Iraqi militant who was the first caliph of the Islamic State (IS) from 2014 until his death in 2019.
The Islamic State of Iraq was a Salafi jihadist militant organization that fought the forces of the U.S.-led coalition during the Iraqi insurgency. The organization aimed to overthrow the Iraqi federal government and establish an Islamic state governed by Sharia law in Iraq.
Tarkhan Tayumurazovich Batirashvili, known by his nom de guerreAbu Omar al-Shishani or Omar al-Shishani, was a Chechen-Georgian jihadist who served as a commander for the Islamic State, and was previously a sergeant in the Georgian Army.
Taha Sobhi Falaha, better known by his nom de guerreAbu Muhammad al-Adnani al-Shami, was a Syrian militant leader who was the official spokesperson and a senior leader of the Islamic State. He was described as the chief of its external operations. He was the second most senior leader of the Islamic State after its leader Abu Bakr al-Baghdadi. Media reports in August 2016 suggested he was in charge of a special unit, known as the Emni, that was established by IS in 2014 with the double objective of internal policing and executing operations outside IS territory.
Many states began to intervene against the Islamic State, in both the Syrian civil war and the War in Iraq (2013–2017), in response to its rapid territorial gains from its 2014 Northern Iraq offensives, universally condemned executions, human rights abuses and the fear of further spillovers of the Syrian Civil War. These efforts are called the war against the Islamic State, or the war against ISIS. In later years, there were also minor interventions by some states against IS-affiliated groups in Nigeria and Libya. All these efforts significantly degraded the Islamic State's capabilities by around 2019–2020. While moderate fighting continues in Syria, as of 2024, ISIS has been contained to a manageably small area and force capability.
On 22 September 2014, the United States officially intervened in the Syrian civil war with the stated aim of fighting the terrorist organization ISIS in support of the international war against it, code named Operation Inherent Resolve. The US currently continues to support the Syrian rebels and the Kurdish-led Syrian Democratic Forces opposed to both the Islamic State and Syrian president Bashar al-Assad.
On 15 June 2014 U.S. President Barack Obama ordered United States forces to be dispatched in response to the Northern Iraq offensive of the Islamic State (IS), as part of Operation Inherent Resolve. At the invitation of the Iraqi government, American troops went to assess Iraqi forces and the threat posed by ISIL.
Operation Inherent Resolve (OIR) is the United States military's operational name for the international war against the Islamic State, including both a campaign in Iraq and a campaign in Syria, with a closely related campaign in Libya. Through 18 September 2018, the U.S. Army's III Armored Corps was responsible for Combined Joint Task Force – Operation Inherent Resolve (CJTF—OIR) and were replaced by the XVIII Airborne Corps. The campaign is primarily waged by American and British forces in support of local allies, most prominently the Iraqi security forces and Syrian Democratic Forces (SDF). Combat ground troops, mostly special forces, infantry, and artillery have also been deployed, especially in Iraq. Of the airstrikes, 70% have been conducted by the military of the United States, 20% by the United Kingdom and the remaining 10% being carried out by France, Turkey, Canada, the Netherlands, Denmark, Belgium, Saudi Arabia, the United Arab Emirates, Australia and Jordan.
The Military force of the Islamic State is the fighting force of the Islamic State (IS). The total force size at its peak was estimated from tens of thousands to over two hundred thousand. IS's armed forces grew quickly during its territorial expansion in 2014. The IS military, including groups incorporated into it in 2014, openly operates and controls territory in multiple cities in Libya and Nigeria. In October 2016, it conquered the city of Qandala in Puntland, Somalia. It conquered much of eastern Syria and western Iraq in 2014, territory it lost finally only in 2019. It also has had border clashes with and made incursions into Lebanon, Iran, and Jordan. IS-linked groups operate in Algeria, Pakistan, the Philippines, and in West Africa. In January 2015, IS was also confirmed to have a military presence in Afghanistan and in Yemen.

On 15 May 2015, 1st SFOD-D operators from the Joint Special Operations Command based in Iraq conducted an operation in Al-Amr, Syria to capture a senior Islamic State of Iraq and the Levant (ISIL) leader named Abu Sayyaf, resulting in his death when he engaged United States forces in combat, after his location was confirmed by surveillance from British SAS operators. Abu Sayyaf's role in ISIL was managing its gas and oil operations; he had built up a network of traders and wholesalers of ISIL-controlled oil that he helped triple energy revenues for the terror group. His other duties for the group included approving expenses to cover the upkeep of slaves, rebuilding oil facilities damaged by airstrikes and counting of revenue. The wife of Abu Sayyaf, Umm Sayyaf was captured and is currently held by U.S. Forces in Iraq. The operation also led to the freeing of a Yazidi woman who was held as a slave. About a dozen ISIL fighters were also killed in the raid, two US officials said. The Syrian Observatory for Human Rights reported that an additional 19 ISIL fighters were killed in the US airstrikes that accompanied the raid. One official said that ISIL Forces fired at the U.S. aircraft, and there was reportedly hand-to-hand combat during the raid. Sikorsky UH-60 Black Hawk helicopters and Bell Boeing V-22 Osprey tilt-rotor aircraft were used to conduct the raid.

In early 2014, the jihadist group Islamic State of Iraq and the Levant captured extensive territory in Western Iraq in the Anbar campaign, while counter-offensives against it were mounted in Syria. Raqqa in Syria became its headquarters. The Wall Street Journal estimated that eight million people lived under its control in the two countries.

Abu Jandal al-Kuwaiti was a leading official of the Islamic State, serving as important military commander, recruiter and propagandist. Known for his command capabilities and popular among his subordinates, Abu Jandal was called "The Lion" among IS fighters and fought in several battles in Syria and Iraq. By late 2016, Abu Jandal had become IS' second highest-ranking commander in Syria and led the defense of its de facto capital Raqqa against the Syrian Democratic Forces (SDF). He was killed by a US airstrike on 26 December 2016.
The Deir ez-Zor campaign, codenamed the al-Jazeera Storm campaign, was a military operation launched by the Syrian Democratic Forces (SDF) against the Islamic State of Iraq and the Levant (ISIL) in Syria's Deir ez-Zor Governorate in 2017 during the Syrian Civil War with the goal of capturing territory in eastern Syria, particularly east and north of the Euphrates river. The U.S.-led Combined Joint Task Force – Operation Inherent Resolve (CJTF–OIR) anti-ISIL coalition provided extensive air support while SDF personnel composed the majority of the ground forces; OIR special forces and artillery units were also involved in the campaign.
The origins of the Islamic State group can be traced back to three main organizations. Earliest of these was the "Jamāʻat al-Tawḥīd wa-al-Jihād" organization, founded by the Jihadist leader Abu Mus'ab al-Zarqawi in Jordan in 1999. The other two predecessor organizations emerged during the Iraqi insurgency against the U.S. occupation forces. These included the "Jaish al-Ta'ifa al-Mansurah" group founded by Abu Omar al-Baghdadi in 2004 and the "Jaysh Ahl al-Sunnah wa’l-Jama’ah" group founded by Abu Bakr al-Baghdadi and his associates in the same year.
The U.S. intervention in the Syrian civil war is the United States-led support of Syrian opposition and Rojava during the course of the Syrian civil war and active military involvement led by the United States and its allies — the militaries of the United Kingdom, France, Jordan, Turkey, Canada, Australia and more — against the Islamic State of Iraq and the Levant (ISIL) and al-Nusra Front since 2014. Since early 2017, the U.S. and other Coalition partners have also targeted the Syrian government and its allies via airstrikes and aircraft shoot-downs.
