Nazi plunder partially coincident with World War II looting of Poland
Nazi plunder (German: Raubkunst) was the stealing of art and other items which occurred as a result of the organized looting of European countries during the time of the Nazi Party in Germany. The looting of Jewish property beginning in 1933 in Germany was a key part of the Holocaust.  Nazis also plundered occupied countries, sometimes with direct seizures, and sometimes under the guise of protecting art through Kunstschutz units. In addition to gold, silver, and currency, cultural items of great significance were stolen, including paintings, ceramics, books, and religious treasures.
Many of the artworks looted by the Nazis were recovered by the Allies' Monuments, Fine Arts, and Archives program (MFAA, also known as the Monuments Men), following the war; however many of them are still missing or were returned to countries but not to their original owners. An international effort to identify Nazi plunder which still remains unaccounted for is underway, with the ultimate aim of returning the items to their rightful owners, their families, or their respective countries.Poland
After the occupation of Poland by German forces in September 1939, the Nazi regime committed genocide against Polish Jews and attempted to exterminate the Polish upper classes as well as its culture. Thousands of art objects were looted, as the Nazis systematically carried out a plan of looting prepared even before the start of hostilities. 25 museums and many other facilities were destroyed. The total cost of German Nazi theft and destruction of Polish art is estimated at 20 billion dollars, or an estimated 43 percent of Polish cultural heritage; over 516,000 individual art pieces were looted, including 2,800 paintings by European painters; 11,000 paintings by Polish painters; 1,400 sculptures; 75,000 manuscripts; 25,000 maps; 90,000 books, including over 20,000 printed before 1800; and hundreds of thousands of other items of artistic and historical value. Germany still has much Polish material looted during World War II. For decades, there have been negotiations between Poland and Germany concerning the return of the looted Polish property.
