During World War II, the Nazi regime systematically looted art and cultural artifacts from occupied territories across Europe. This theft targeted museums, galleries, and private collections, resulting in the seizure of thousands of valuable works, including pieces by renowned artists like Vincent van Gogh and Pablo Picasso. The stolen art was often used to promote Nazi propaganda or was hoarded by high-ranking officials. After the war, efforts to recover these stolen artworks led to the establishment of various organizations and legal frameworks aimed at returning the looted items to their rightful owners or their descendants.
