The main cause of civil wars between different ethnic and religious groups in Iraq is a complex combination of factors. These include historical grievances between Sunni Arabs, Shia Arabs, and Kurds, sectarian tensions fueled by political manipulation, competition for power and resources, and external interventions by regional actors. Additionally, the legacy of decades of authoritarian rule under Saddam Hussein, the 2003 US-led invasion of Iraq, and the subsequent collapse of state institutions have all contributed to the deep-seated divisions and conflicts within Iraqi society.
