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 (ISIS) or the international military intervention against the Islamic State (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 ‹See RfD› 2025, ISIS has been contained to a manageably small area and force capability.
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.

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.

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.

Originally set up as al-Barakah Province to govern IS territories in al-Hasakah Governorate, the province shifted south after 2016 due to the territorial losses to the YPG/YPJ. Having been demoted from province to district in 2018, al-Barakah administered a small strip of land along the Euphrates in Deir ez-Zor Governorate until the Battle of Baghuz Fawqani; since then the "territory" has turned into an insurgency.
Opposition–ISIL conflict during the Syrian Civil War started after fighting erupted between Syrian opposition groups and the Islamic State of Iraq and the Levant (ISIL). In early January 2014, serious clashes between the groups erupted in the north of the country. Opposition groups near Aleppo attacked ISIL in two areas, Atarib and Anadan, which were both strongholds of the fundamentalist Sunni organization. Despite the conflict between ISIL and other rebels, one faction of ISIL has cooperated with the al-Nusra Front and the Green Battalion to combat Hezbollah in the Battle of Qalamoun. By 2018.
The Eastern Syria insurgency is an armed insurgency being waged by remnants of the Islamic State of Iraq and the Levant (ISIL) and both pro and anti-Syrian government Arab nationalist insurgents, against the Autonomous Administration of North and East Syria (AANES), its military, and their allies in the US-led Combined Joint Task Force – Operation Inherent Resolve (CJTF–OIR) coalition.
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. Although the other two predecessor organizations emerged during the Iraqi insurgency against the U.S. occupation forces which 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 modern iteration of the Islamic State was formed after the U.S. occupational forces outlawed the Iraqi branch of the Arab Socialist Ba'ath Party putting the Sunni soldiers and bureaucrats out of work.
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.
