Raubkunst
During the Second World War, Germany tried to destroy Poland completely and exterminate its population as well as culture. Countless art objects were looted, as Germany systematically carried out a plan of looting prepared even before the start of hostilities (see also Nazi plunder). Twenty-five museums and many other facilities were destroyed. The total cost of German theft and destruction of Polish art is estimated at 20 billion dollars, or an estimated 43% 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). Soviet troops afterward contributed to the plunder as well.
