The following is a timeline of the Syrian civil war from August to December 2014. Information about aggregated casualty counts is found at Casualties of the Syrian Civil War.
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.
The following lists events that happened during 2014 in Iraq.
Opération Chammal is a French military operation in Iraq and Syria launched to help curtail the expansion of the Islamic State of Iraq and the Levant and to support the Iraqi Army. Its name comes from the Shamal, a northwesterly wind that blows over Iraq and the Persian Gulf states.
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 Battle of Baiji took place in Baiji, Iraq, lasting from late October 2014 to late October 2015. In mid-November 2014, Iraqi forces retook the city of Baiji, and re-entered the Baiji Oil Refinery. However, fighting continued in the region, and on 21 December 2014, ISIL forces took Baiji and put the Baiji oil refinery under siege once again, before Iraqi forces recaptured the city on 22 October. It gave Iraqi forces complete control of the highway stretching from Baghdad to Baiji, and allowed Iraqi forces to use Baiji as a base for launching a future assault on Mosul.
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.
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.
Oil production and smuggling was the largest source of revenue for the finances of the Islamic State in Syria and Iraq until the complete loss of its territory in 2019. Most oil extracted was distributed for use within the Islamic State, but some was also smuggled to surrounding states at below market price.
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 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.
The Shirqat offensive, codenamed Operation Conquest or Operation Fatah, was an offensive against the positions of the Islamic State of Iraq and the Levant (ISIL) in and around the district of Al-Shirqat District to reach the city of Mosul.
The Palmyra offensive in December 2016 was a military operation launched by the military of ISIL which led to the re-capture of the ancient city of Palmyra, and an unsuccessful ISIL attack on the Tiyas T-4 Airbase to the west of the city. ISIL previously controlled the city from May 2015 until March 2016.
The 2017 Mosul airstrike, was an American bombing in the al-Aghawat al-Jadidah neighborhood in western Mosul on 17 March 2017 that killed between 200 and 300 civilians. The incident was the largest single death toll inflicted by a coalition air strike since the 2003 invasion of Iraq by U.S. forces.
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.
From November 2015 to 2019, the United States and allies carried out a large series of both airstrikes and drone strikes to intervene in Libya in its revived conflict in support of the Tripoli-based Government of National Accord against the ISIL presence in the region. By 2019, the ISIL branch had been largely driven from holding Libyan territory, and US strikes ceased.
The US intervention in the Syrian civil war is the United States-led support of Syrian opposition and the Federation of Northern Syria 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.
