The Peshmerga comprise the standing military of Kurdistan Region, an autonomous political entity within the Republic of Iraq. According to the Constitution of Iraq, the Peshmerga and their security subsidiaries are solely responsible for the security of Kurdistan Region, chiefly due to the fact that the Iraqi Armed Forces are forbidden to enter Iraqi Kurdistan. These subsidiaries include Asayish, Parastin û Zanyarî, and Zêrevanî. The Peshmerga's history dates back to the 18th century, when they began as a strictly tribal pseudo-military border guard under the Ottoman Turks and the Safavid Iranians. By the 19th century, they had evolved into a disciplined and well-trained guerrilla force.
The Sinjar Resistance Units is a Yazidi militia formed in Iraq in 2007 to protect Yazidis in Iraq in the wake of attacks by Sunni Islamist insurgents. It is the second largest Yazidi militia, after the Êzîdxan Protection Force (HPÊ). However, it is much more active than the HPÊ in fighting against the Islamic State of Iraq and the Levant (ISIL).
The Sinjar District or the Shingal District is a district of the Nineveh Governorate. The district seat is the town of Sinjar. The district has two subdistricts, al-Shemal and al-Qayrawan. The district is one of two major population centers for Yazidis, the other being Shekhan District.
The Iraqi–Kurdish conflict consists of a series of wars, rebellions and disputes by the Kurds against the central authority of Iraq starting in the 20th century shortly after the defeat of the Ottoman Empire in World War I. Some put the marking point of the conflict beginning to the attempt by Mahmud Barzanji to establish an independent Kingdom of Kurdistan, while others relate to the conflict as only the post-1961 insurrection by the Barzanis. Since the US-led invasion of Iraq and the subsequent adoption of federalism and the recognition of the Kurdistan Region (KRI) as a federal entity in the new Iraqi constitution, the number and scope of armed clashes between the central government of Iraq and the Kurds have significantly decreased. In spite of that, however, there are still outstanding issues that continue to cause strife such as the disputed territories of northern Iraq and rights to export oil and gas, leading to occasional disputes and armed clashes. In September 2023, following a series of punitive measures by the central government in Iraq against KRI, Masrour Barzani sent a letter to the President of the United States expressing concerns about a possible collapse of the Kurdistan Region, and calling for the United States to intervene.
The Northern Iraq offensive began on 4 June 2014, when the Islamic State of Iraq and Levant, assisted by various insurgent groups in the region, began a major offensive from its territory in Syria into Iraq against Iraqi and Kurdish forces, following earlier clashes that had begun in December 2013 involving guerillas.
The Battle of Zumar was fought between the Islamic State of Iraq and the Levant and Kurdish Peshmerga troops over the city of Zumar in Nineveh province in northern Iraq. It started when IS launched an offensive on Zummar from 1–4 August 2014, resulting in its capture. On 25 October, after US airstrikes, Kurdish Peshmerga troops succeeded in recapturing the city, after an unsuccessful attempt to hold it in September.
The War in Iraq was an armed conflict between Iraq and its allies and the Islamic State. Following December 2013, the insurgency escalated into full-scale guerrilla warfare following clashes in the cities of Ramadi and Fallujah in parts of western Iraq, and culminated in the Islamic State offensive into Iraq in June 2014, which lead to the capture of the cities of Mosul, Tikrit and other cities in western and northern Iraq by the Islamic State. Between 4–9 June 2014, the city of Mosul was attacked and later fell; following this, Prime Minister Nuri al-Maliki called for a national state of emergency on 10 June. However, despite the security crisis, Iraq's parliament did not allow Maliki to declare a state of emergency; many legislators boycotted the session because they opposed expanding the prime minister's powers. Ali Ghaidan, a former military commander in Mosul, accused al-Maliki of being the one who issued the order to withdraw from the city of Mosul. At its height, ISIL held 56,000 square kilometers of Iraqi territory, containing 4.5 million citizens.
Between 1 and 15 August 2014, the Islamic State of Iraq and the Levant (ISIL) expanded territory in northern Iraq under their control. In the region north and west from Mosul, the Islamic State conquered Zumar, Sinjar, Wana, Mosul Dam, Qaraqosh, Tel Keppe, Batnaya and Kocho, and in the region south and east of Mosul the towns Bakhdida, Karamlish, Bartella and Makhmour
The following lists events that happened during 2014 in Iraq.
The Sinjar offensive was a combination of operations of Kurdish Peshmerga, PKK and People's Protection Units forces in December 2014, to recapture regions formerly lost to the Islamic State of Iraq and the Levant in their August offensive.
This is a timeline of events during the War in Iraq in 2015.
The Mosul offensive (2015) was an offensive launched by Kurdish Peshmerga forces on 21 January 2015, with the objective of severing key ISIL supply routes to Mosul, Iraq, and to recapture neighboring areas around Mosul. The effort was supported by US-led coalition airstrikes. The Iraqi Army was widely expected to launch the planned operation to retake the actual city of Mosul in the Spring of 2015, but the offensive was postponed to October 2016, after Ramadi fell to ISIL in May 2015.
The November Sinjar offensive was a combination of operations of Kurdish Peshmerga, PKK, and Yezidi Kurd militias in November 2015, to recapture the city of Sinjar from the Islamic State of Iraq and the Levant. It resulted in a decisive victory for the Kurdish forces, who expelled the ISIL militants from Sinjar and regained control of Highway 47, which until then had served as the major supply route between the ISIL strongholds of Raqqa and Mosul.
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.
The Nineveh Plains offensive was a battle in which the Islamic State of Iraq and the Levant (ISIL) mounted a multi-front attack against Peshmerga forces in the area north and east of Mosul, in December 2015. The attack—the most significant ISIL military operation in the area in months, was successfully repelled by the Kurdish forces and was followed by a coalition air counter-offensive.
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 Battle of Kirkuk (2017), part of the 2017 Iraqi–Kurdish conflict, was a military deployment by the Iraqi Security Forces to retake Kirkuk Governorate from the Peshmerga after the latter ignored repeated warnings to withdraw, sparking clashes between the two forces. The advance began on 15 October 2017, with the city of Kirkuk being retaken the following day. Iraqi central government forces continued their advances in subsequent days, routing the Peshmerga forces across vast swathes of territory in northern Iraq.
The 2017 Iraqi–Kurdish conflict, also known as the Kirkuk crisis, was a conflict in which the Iraqi government retook disputed territories in Iraq which had been held by the Peshmerga since ISIL's Northern Iraq offensive in 2014. The conflict began on 15 October 2017 after tensions arising from the Kurdistan Region independence referendum of 25 September. The tension between the federal Iraqi government and Kurdistan Region escalated into conflict when the Peshmerga ignored repeated warnings to return Kirkuk to Iraqi government forces. Part of the conflict was the Battle of Kirkuk, when Iraqi forces routed Peshmerga forces from the city in a surprise dawn-offensive, marking the beginning of clashes.
The Ninewa Operational Command (NOC) is a interagency command of the Iraqi Armed Forces and Iraqi Ministry of the Interior. Up until 2014 it had its headquarters in Mosul. It holds responsibility for all anti-ISIS operations in Ninewa Governorate.
