This article contains a timeline of events from January 2015 to December 2015 related to the Islamic State of Iraq and the Levant (ISIL/ISIS). This article contains information about events committed by or on behalf of the Islamic State, as well as events performed by groups who oppose them.
ISIL's official spokesman Abu Muhammad al-Adnani released an audio statement in which he accepted the earlier pledge of allegiance and announced the expansion of ISIL's caliphate with the creation of Wilayat Khorasan (Khurasan Province), a historical region incorporating parts of modern-day Afghanistan and Pakistan. Hafiz Khan Saeed was appointed as its local leader, or Wāli (Governor). [1] [2] Abdul Rauf was named as Khan's deputy, however he was killed by a US drone strike in Afghanistan several weeks later.

A group of IMU militants in northern Afghanistan, led by Sadulla Urgenji, released a video in which they stated they no longer view the Taliban's Mullah Omar as leader and pledged allegiance to ISIL's Abu Bakr al-Baghdadi. [90] [91]
At least 38 ISIS fighters were killed in airstrikes by the Damascus regime against Palmyra and two other towns held by ISIS in Homs province. [232]
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 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 2024, ISIS has been contained to a manageably small area and force capability.
The siege of Kobanî was launched by the Islamic State (IS) on 13 September 2014, in order to capture the Kobanî Canton and its main city of Kobanî in northern Syria, in the de facto autonomous region of Rojava.
The Military 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.
The Eastern al-Hasakah offensive was launched in the Al-Hasakah Governorate during the Syrian Civil War, by the Kurdish-majority People's Protection Units, Assyrian Christian militias, and allied Arab forces against the jihadist Islamic State of Iraq and the Levant, with the intent of retaking the areas of the Jazira Canton that had been captured by ISIL. Subsequently, the Syrian Armed Forces also launched an assault against the jihadists, without coordinating with the YPG.
The Battle of Sarrin refers to a military operation during 2015 in the northeastern Aleppo Governorate, during the Syrian Civil War, conducted by Kurdish YPG and allied forces against the Islamic State of Iraq and the Levant in the town of Sarrin, in an effort to capture the town and the surrounding region.
The Timeline of the War in Iraq covers the War in Iraq, a war which erupted that lasted in Iraq from 2013 to 2017, during the first year of armed conflict.
The Tell Abyad offensive or Martyr Rubar Qamışlo operation was a military operation that began in late May 2015 in the northern Raqqa Governorate, during the Syrian Civil War. It was conducted by the Kurdish-majority People's Protection Units (YPG) and the Free Syrian Army (FSA) against the Islamic State of Iraq and the Levant. The offensive took place from the end of May until July 2015. The campaign was the second phase of the Kurdish Operation Commander Rûbar Qamishlo, which began with the Al-Hasakah offensive, and involved the merger of the Kobanî offensive with the former. The focus of the campaign was to capture the key border town of Tell Abyad, and to link the Kobanî and Jazira Cantons in Northern Syria.
The Kobanî massacre was a combination of suicide missions and attacks on Kurdish civilians by the Islamic State of Iraq and the Levant on the Kurdish-majority city of Kobanî, beginning on Thursday, 25 June 2015, and culminating on Friday, 26 June 2015. The attacks continued into 28 June 2015, with the last remaining ISIL militant being killed on the following day. The attacks resulted in 223–233 civilians dead, as well as 35–37 Kurdish militiamen and at least 79 ISIL assailants. It was the second-largest massacre committed by ISIL since it declared a caliphate in June 2014.
The 2015 Battle of al-Hasakah started as an offensive launched in the Al-Hasakah Governorate during the Syrian Civil War, in which the Islamic State of Iraq and the Levant (ISIL) attempted to capture the city of Al-Hasakah, which was divided into two areas held separately by the Syrian Armed Forces and the Kurdish People's Protection Units (YPG). On 17 July, YPG-led forces captured all of the roads and villages surrounding Al-Hasakah, fully besieging the ISIL militants remaining inside of the city. On 28 July, YPG forces and the Syrian Army expelled ISIL from most of Al-Hasakah, with two ISIL pockets persisting near the Al-Zuhour District and the southern entrance. On 1 August, the city was fully cleared of ISIL fighters.
The Battle of Sarrin was a military operation during 2015 in the northeastern Aleppo Governorate, during the Syrian Civil War, in which the Kurdish YPG and Free Syrian Army forces captured the town of Sarrin and the surrounding region from the Islamic State of Iraq and the Levant (ISIL).
The following is a timeline of the Syrian Civil War from January to July 2015. Information about aggregated casualty counts is found at Casualties of the Syrian Civil War.
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.
This is a timeline of events during the War in Iraq in 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 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. 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.
