What caused widespread looting in Iraq after the 2003 invasion?

Following the collapse of the Baʿathist regime in April 2003, Iraq’s major cities experienced a wave of widespread looting that primarily targeted government offices, public institutions, and sites such as the Iraq Museum.

This breakdown in law and order occurred as the previous government structure disintegrated, leaving a power vacuum in the immediate aftermath of the U.S.-led invasion. The rapid fall of the regime and the subsequent transition to the Coalition Provisional Authority created a period of instability where occupying forces struggled to maintain security across major urban centers.12

While the initial combat phase concluded by late April, the collapse of state authority facilitated both common criminal activity and acts of reprisal against the former ruling clique. Restoring order became one of the most arduous tasks for the occupying forces, a challenge that was further complicated by the emergence of an escalating insurgency and guerrilla warfare in the months that followed.12
