Northern Iraq offensive (2014–2017) The Northern Iraq offensive (2014–2017) comprised a series of campaigns and counteroffensives across the Nineveh Governorate, Kirkuk Governorate, Dohuk Governorate and Erbil Governorate fought between Islamic State of Iraq and the Levant forces and an array of local and regional actors including the Peshmerga, Iraqi Armed Forces, and Popular Mobilization Forces. The offensive unfolded amid the wider War in Iraq (2013–2017), intersecting with the Iraqi–Kurdish conflict and the Syrian Civil War and produced profound military, political, and humanitarian consequences across northern Mesopotamia.

Background

The offensive followed ISIL's June 2014 capture of Mosul and rapid advance from Anbar Governorate and Nineveh Plains into Kurdish-held territories, prompting defensive operations by the Peshmerga under the Kurdistan Regional Government leadership of Masoud Barzani and coordination with the Iraqi Armed Forces led by Haider al-Abadi. ISIL's declaration of a caliphate under Abu Bakr al-Baghdadi transformed localized battles such as the Battle of Mosul (2014) and the seizure of Sinjar into flashpoints involving Yazidi populations, Assyrian communities, and transnational jihadist networks. The offensive intersected with regional dynamics involving Turkey, Iran, United States, Russia, and Saudi Arabia.

Belligerents and forces

Principal belligerents included ISIL's hierarchical command and local emirs drawn from Al-Qaeda in Iraq progeny, confronted by the Peshmerga forces organized by the Kurdistan Regional Government, units of the Iraqi Army and Iraqi Counter-Terrorism Service, and Shia militias within the Popular Mobilization Forces such as Kata'ib Hezbollah and Badr Organization. Minority militias—Nineveh Plains Protection Units, Assyrian militias, Yazidi militias like Sinjar Resistance Units (YBS), and Christian brigades—also fought. International actors supplied training and materiel: the United States Department of Defense, United Kingdom Ministry of Defence, French Armed Forces, Australian Defence Force, and Turkish Armed Forces conducted advisory, logistical, or combat sorties. Regional intelligence and proxy involvement by Islamic Revolutionary Guard Corps elements, Hezbollah, and Quds Force advisors influenced operations and battlefield momentum.

Course of the offensive

From 2014 onward ISIL consolidated control over Nineveh Plains and urban centers, then faced counteroffensives: the Sinjar offensive (2015), Kirkuk battles, and the long-running Battle of Mosul (2016–17), in which Iraqi Special Operations Forces and Peshmerga advanced with international coalition air support. Operations saw complex episodes such as the 2014 Fall of Mosul aftermath, the 2015 Kobane reverberations, and multi-front clashes near Tal Afar, Baaj District, and Sharqat. ISIL employed guerrilla tactics, suicide car bombs, and tunnel networks while defenders leveraged US-led coalition intelligence, reconnaissance, and artillery. Territorial shifts included periodic Kurdish advances into disputed territories like Kirkuk city and later Iraqi government retakes in 2017 during a strategic pivot by Abadi's forces that accompanied the Battle of Mosul (2016–17) liberation campaign and the Hawija offensive (2017).

Humanitarian impact and civilian displacement

The offensive precipitated mass displacement affecting Yazidis, Assyrians, Shabak, Kurds, and Armenians as ISIL sieges and ethnic-religious persecution led to atrocities including mass executions, sexual slavery, and forced conversion in locations such as Sinjar Mountain and Mosul Old City. Humanitarian crises prompted interventions by United Nations High Commissioner for Refugees, International Committee of the Red Cross, Médecins Sans Frontières, and UNICEF with refugee flows to Duhok, Erbil, Sulaymaniyah, and cross-border camps in Turkey and Jordan. Humanitarian corridors, sieges, and shortages of potable water, medical supplies, and shelter created protracted internally displaced persons crises and complex restitution issues for Property law and community returns.

International involvement and air campaigns

A US-led Combined Joint Task Force – Operation Inherent Resolve coalition conducted the majority of airstrikes along with sorties by Royal Air Force, Armée de l'Air, Luftwaffe, and Royal Australian Air Force assets targeting ISIL nodes, logistics, and command-and-control. Turkey conducted operations ostensibly targeting Kurdistan Workers' Party elements while coordinating and clashing diplomatically over Kurdish advances in Kirkuk. Iran provided advisory support and facilitated Shia militia deployment. Intelligence sharing by CENTCOM and surveillance from MQ-9 Reaper and MQ-1 Predator UAVs supported precision strikes and urban assault planning, though air campaigns prompted debates about civilian casualties and International humanitarian law.

Aftermath and territorial control changes

By late 2017 ISIL's territorial caliphate in northern Iraq had effectively collapsed following the fall of Mosul and Tal Afar; control of disputed areas shifted between the Kurdistan Regional Government and the Iraqi government, culminating in the October 2017 Kurdish independence referendum aftermath and Iraqi retaking of Kirkuk during a federal counteroperation. The offensive's end-state left contested governance in the Nineveh Plains, contested resource claims over Iraqi Kurdistan oil fields, and ongoing security challenges with insurgent cells, improvised explosive devices, and reconciliation issues overseen by United Nations Assistance Mission for Iraq and reconstruction efforts involving World Bank and bilateral donors. The region continues to grapple with restitution for displaced minorities, heritage destruction, and the legacy of ISIL's occupation.
