consequence of looting during war, natural disaster and riot
Looted art has been a consequence of looting during war, natural disaster and riot for centuries. Looting of art, archaeology and other cultural property may be an opportunistic criminal act or may be a more organized case of unlawful or unethical pillage by the victor of a conflict. The term "looted art" reflects bias, and whether particular art has been taken legally or illegally is often the subject of conflicting laws and subjective interpretations of governments and people; use of the term "looted art" in reference to a particular art object implies that the art was taken illegally.
Related terms include art theft (the stealing of valuable artifacts, mostly because of commercial reasons), illicit antiquities (covertly traded antiquities or artifacts of archaeological interest, found in illegal or unregulated excavations), provenance (the origin or source of a piece of art), and art repatriation (the process of returning artworks and antiques to their rightful owners).
