Christians have a long history in Iraq’s north. Some of the earliest followers of the religion settled there and established communities around Mosul. When the Islamic State poured into the region, Iraq’s Christians fled, in many cases – like nuns from the Syriac Catholic Dominican Sisters of Saint Catherine of Sienna in Qaraqosh – with only a few hours notice. Two years later, when the Islamic State was pushed out, they returned to the devastation left behind.
