 In 2008, the German Historic Museum of Berlin published a database with paintings collected for the "Führermuseum" and for other museums in the German Reich.The German occupation of Paris began on 14 June 1940, and on 30 June Hitler ordered that artworks in the French national collection be "safeguarded", and in particular "ownerless" art and historical documents – meaning works which were the property of Jews and could therefore be confiscated from them – be "protected" as well.Three days later, the German ambassador in France, Otto Abetz, ordered the confiscation of the collections of the 15 most important art dealers in the city, most of whom were Jewish.
