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.

The Sinjar massacre marked the beginning of the genocide of Yazidis by ISIL, the killing and abduction of thousands of Yazidi men, women and children. It took place in August 2014 in Sinjar city and Sinjar District in Iraq's Nineveh Governorate and was perpetrated by the Islamic State of Iraq and the Levant (ISIL).

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.

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 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.
