The notable artifact that was looted during the invasion of Iraq by U.S. forces in 2003 was the Baghdad Museum. The museum housed a vast collection of ancient artifacts reflecting Mesopotamian history and culture. Following the invasion, widespread looting occurred, resulting in the loss of thousands of invaluable items, which sparked international outrage and highlighted the importance of cultural heritage preservation. The looting represented a significant loss for archaeological history and raised concerns about the protection of cultural sites during military conflicts. Efforts to recover these artifacts continue to this day.
