Most of Bozan's population of 6000 people fled to Zakho at the approach of the Islamic State of Iraq and the Levant (ISIL) offensive in August 2014, whilst a number of locals remained to defend the village. However, the ISIL fighters did not reach the village and its population began to return a month later. By June 2018, the village's population had recovered to 5000 people with 1000 families, and was also inhabited by roughly 300 displaced Yazidi families from Sinjar.
