The Battle of Mosul (2016–2017) (Arabic: معركة الموصل, Ma'rakat al-Mawṣil; Sorani Kurdish: شەڕی مووسڵ, Şeriy Mûsil) was a major military campaign launched by the Iraqi Government forces with allied militias, the Kurdistan Regional Government, and international forces to retake the city of Mosul from the Islamic State of Iraq and the Levant (ISIL), which had seized the city in June 2014. During the military intervention against ISIL, Iraqi and Peshmerga forces had already made unsuccessful attempts to retake the city in 2015 and again in 2016, despite limited gains.
Despite its rich history and culture, Mosul was deemed off limits to the West due to ISIS's past control of the city. When Mosul was captured by ISIS in June 2014, ISIS has consolidated control over all aspects of society, including imposing Sharia law and actively persecuting non-Sunni residents. Even if the Iraqi army managed to recapture the entire city in June 2017( except some small house blocks), the city is in ruins and the danger of ISIS is still relatively present in the city.
