Following Saddam Hussein's removal from power, a power vacuum emerged in Iraq which led to various factions and groups vying for control. This instability ultimately led to the rise of ISIS (Islamic State of Iraq and Syria), a terrorist organization that declared the formation of a caliphate in Iraq and Syria. Additionally, sectarian tensions between Sunni and Shia Muslims escalated, leading to a civil war between different ethnic and religious groups in Iraq. Many Iraqi civilians were displaced and became refugees, fleeing to neighboring countries for safety.
