Before the 3rd of August 2014, the Sinjar District consisted of different religions and nationalities. The Yazidis were the largest religion but other religious groups such as Islam, Christianity, and Shabak were also living in Sinjar. These Iraqi communities lived well compared to other rural areas in Iraq.
After the American war in 2003, the Sinjar District was facing its best time in history thanks to scientific progress, better well-being in life, and urbanization progress.
