Nazi plunder

• 1. Introduction

  ›

  Nazi plunder stands as the largest organized theft of art and cultural property in recorded history. By the end of World War II, the United States government estimated that Nazi forces had seized or coerced the sale of roughly one fifth of all Western art then in existence. That amounts to approximately a quarter of a million pieces of art, ripped from homes, synagogues, museums, and libraries across a continent.

  The looting was not improvised. It began in Germany in 1933 the moment Adolf Hitler became chancellor, and it spread into every country the Reich occupied. Paintings, ceramics, books, gold, silver, religious treasures, even home furnishings: nothing was beyond reach. Special task forces were created with the sole purpose of cataloguing and confiscating the most valuable collections in Europe.

  At the center of this story is an uncomfortable truth. Well over 100,000 items have never been returned to their rightful owners. Some surface in auction houses. Some hang unrecognized in museum galleries. And some, like a Renoir and a Pissarro that appeared on Interpol's twelve most wanted list in 1979, have simply vanished. What follows is the story of how that happened, who drove it, and why the search continues today.

• 2. Hitler's Obsession With Art

  ›

  Adolf Hitler was denied admission to the Vienna Academy of Fine Arts, and that rejection shaped the ideology of an empire. In his book Mein Kampf, Hitler attacked modern art with ferocity, calling Cubism, Futurism, and Dadaism products of a decadent twentieth-century society. When he came to power, those opinions became state policy.

  The Nazis declared all such work degenerate art and removed it from Germany's public museums. What replaced it were classical portraits and landscapes by Old Masters, particularly those of Germanic origin. The art stripped from museums was either sold or destroyed. The funds raised were earmarked for an ambitious project: a grand European Art Museum in Linz, Austria, Hitler's home city, which he planned to transform into the Third Reich's cultural capital.

  Hitler hired architects and worked from his own designs to build galleries and museums that would collectively be known as the Führermuseum. He believed that the finest art in the world rightfully belonged to Germany, having been looted during the Napoleonic wars and the First World War. Art historian Hans Posse was given the task of assembling the collection. Other senior Nazis saw Hitler's passion as their own opportunity, and Reichsmarschall Hermann Göring and Foreign Affairs minister Joachim von Ribbentrop both began growing private collections on the back of German military conquest.

• 3. The Machinery of Theft

  ›

  In 1940, a new organization called the Einsatzstab Reichsleiter Rosenberg für die Besetzten Gebiete, known by its initials ERR, was formed and placed under Alfred Rosenberg. Its first operating unit, the Dienststelle Westen, was based in Paris and initially tasked with collecting Jewish and Freemasonic books and documents for destruction or study.

  Hermann Göring, who effectively controlled the ERR, soon redirected it. Late in 1940 he ordered the unit to seize Jewish art collections across occupied France, Belgium, and the Netherlands. All loot was to be collected at a single location: the Museum Jeu de Paume in Paris, where art historians and other personnel inventoried everything before shipping it to Germany. Göring personally commanded that the first division of spoils would go between Hitler and himself.

  Art dealer Bruno Lohse became Göring's man inside the ERR. From the end of 1940 to the end of 1942, Göring traveled to Paris twenty times. Lohse staged twenty expositions of freshly looted objects at the Jeu de Paume specifically for Göring, from which Göring selected at least 594 pieces for his own collection. By the end of the ERR's operation, the organization had seized 21,903 art objects from German-occupied countries.

  Other looting bodies ran parallel to the ERR. The Dienststelle Mühlmann, under Kajetan Mühlmann, operated primarily in the Netherlands and Belgium. The Sonderkommando Kuensberg, connected to Ribbentrop, worked first in France, then in Russia and North Africa. The von Ribbentrop Battalion entered libraries in occupied territories to strip scientific, technical, and informational materials. Well-known Jewish collections, including those of the Rothschilds, the Rosenbergs, the Wildensteins, and the Schloss family, were prime targets.

• 4. Plunder of Jewish Books

  ›

  France was the first country swept for Jewish books. The Nazis took 50,000 volumes from the Alliance Israélite Universelle, 10,000 from L'Ecole Rabbinique, one of Paris's most significant rabbinic seminaries, and 4,000 from the Federation of Jewish Societies of France. They seized 20,000 books from the Lipschuetz Bookstore and another 28,000 from the Rothschild family's personal collection, then moved through private Parisian homes gathering thousands more.

  From France, the campaign moved to the Netherlands. Raiders took 16,000 volumes from Hans Furstenberg, a wealthy Jewish banker, 25,000 from the Bibliotheek van het Portugeesch Israelietisch Seminarium in Amsterdam, 4,000 from Ashkenazic Beth ha-Midrasch Ets Haim, and 100,000 volumes from the Bibliotheca Rosenthaliana.

  In 1943, the Nazis arrived in Italy and packaged up every book from the central synagogue of Rome, which housed both the Italian Rabbinic College library and the Jewish community library. The goal was not merely to steal. The original purpose of the ERR's book-collecting mission was to gather all of European Jewry's written record and burn it.

  The International Archives for the Women's Movement in the Netherlands, looted in 1940, had a different postwar fate. The confiscated records were sent to Berlin, then moved to the Sudetenland, then captured by the Red Army and stored in the KGB's special archive in Moscow. On the 14th of January 1992, historian Marc Jansen reported the discovery in the NRC Handelsblad. Despite agreements reached almost immediately afterward, bureaucratic delays kept the archives frozen for eleven years. A partial recovery came in 2003, returning papers of feminists including Aletta Jacobs and Rosa Manus, along with roughly 4,650 books and periodicals. Approximately half of the original collection remains unrecovered.

• 5. Eastern Europe and the Soviet Union

  ›

  After Operation Barbarossa began, the scale of plunder in Eastern Europe exceeded even the systematic looting of the west, though the character of the theft was different. In 1943 alone, nine million tons of cereals, two million tons of fodder, three million tons of potatoes, and 662,000 tons of meat were sent back to Germany. During the occupation, roughly twelve million pigs and thirteen million sheep were seized. The total value of this agricultural plunder is estimated at four billion Reichsmarks.

  Cultural destruction was equally vast. ERR teams and the Wehrmacht visited 375 archival institutions, 402 museums, 531 institutes, and 957 libraries in Eastern Europe alone. From the Soviet Union, one account estimates that one hundred thousand geographical maps were taken, gathered on ideological grounds, for academic research, or as collector's items. In the Russian Soviet Federative Socialist Republic, 173 museums were found to have been plundered, with looted items numbering in the hundreds of thousands.

  On the 2nd of November 1942, the Soviet government formed the State Extraordinary Commission to investigate Nazi crimes in the USSR. After the war, the Commission documented damage to 64 of the most valuable Soviet museums out of 427 that had been damaged in total. A successor body, the Russian State Commission for the Restitution of Cultural Valuables, eventually catalogued losses from 14 museums and libraries across regions including Voronezh, Kursk, Pskov, and Rostov oblasts, publishing the findings in fifteen volumes made available online. Those volumes record detailed information on 1,148,908 individual lost items, and cataloguing work for other damaged museums is still ongoing.

  Poland's losses were catalogued with unusual specificity. After German forces occupied the country in September 1939, the Nazis looted over 516,000 individual art pieces, including 2,800 paintings by European painters, 11,000 by Polish painters, 1,400 sculptures, 75,000 manuscripts, 25,000 maps, and 90,000 books. The total cost of Nazi theft and destruction of Polish art is estimated at twenty billion dollars, representing roughly 43 percent of Poland's cultural heritage.

• 6. The Monuments Men and Aftermath

  ›

  On the 21st of November 1944, William J. Donovan, at the request of Owen Roberts, established the Art Looting Investigation Unit within the OSS. Its mandate was to collect information on the looting, identify key suspects, and build cases for prosecution and restitution. Interrogations of suspects were conducted in Bad Aussee, Austria. The unit's final report ran to 175 pages organized into Detailed Interrogation Reports, Consolidated Interrogation Reports, and a Red Flag list naming individuals involved in the spoliation network across Germany, France, Switzerland, the Netherlands, Belgium, Italy, Spain, Portugal, Sweden, and Luxembourg.

  The Allies' Monuments, Fine Arts, and Archives program, commonly known as the Monuments Men and Women, faced an immediate practical challenge. In the summer of 1945, Captain Walter Farmer became the first director of the Wiesbaden Collecting Point. The first shipment of objects arriving there included antiquities, Egyptian art, Islamic artifacts, and paintings from the Kaiser Friedrich Museum, as well as materials from the Reichsbank and looted Polish liturgical collections. At its peak, Wiesbaden stored, identified, and restituted approximately 700,000 individual objects.

  The Allies discovered more than 1,050 repositories across Germany and Austria. Much of the looted material had been moved into salt mines and caves chosen for their stable humidity and temperature: facilities at Merkers, Altaussee, and Siegen were among the most significant. Between 1943 and 1945, the mines at Altaussee alone held some 4,700 pieces of art.

  The Washington Conference on Nazi-looted assets of Holocaust victims, held from the 30th of November to the 3rd of December 1998, was attended by more than 49 countries and 13 private entities. It was built on the earlier Nazi Gold Conference held in London in 1997. Afterward, the Association of Art Museum Directors developed guidelines requiring museums to review the provenance of their collections for the period 1933 to 1945.

• 7. Art Still Missing

  ›

  Roughly twenty percent of the art in Europe was looted by the Nazis, and well over 100,000 items have never been returned to their rightful owners. The majority of what remains missing consists of everyday objects: china, crystal, silver. But among the missing are also works of major significance.

  Paul Rosenberg's collection was scattered across Europe after Hermann Göring appointed ERR-approved dealers, including Hildebrand Gurlitt, to liquidate works designated as degenerate and convert them to foreign currency. Today, approximately seventy of Rosenberg's paintings remain unaccounted for. Among them are the Picasso watercolor Naked Woman on the Beach, painted in Provence in 1923; seven works by Matisse; and the Portrait of Gabrielle Diot by Degas.

  In early 2012, roughly 1,500 pieces of art were discovered at the Munich home of Cornelius Gurlitt, son of Hildebrand Gurlitt. Some 200 to 300 pieces were suspected to be looted, potentially including works shown at the Nazis' own degenerate art exhibitions before the war. The collection contained works by Marc Chagall, Otto Dix, Henri Matisse, Renoir, and Max Liebermann.

  In 2010, as workers extended an underground line in Berlin from Alexanderplatz toward the Brandenburg Gate, sculptures from the original degenerate art exhibition were unearthed in the cellar of a private house near the Rote Rathaus. Among them was a bronze cubist-style statue of a female dancer by Marg Moll. Those works are now on display at the Neues Museum.

  In April 2026, the Flemish government announced a permanent commission to handle restitution claims related to Nazi-looted art. Flemish Minister of Culture Gennez stated that the widespread plundering of Jewish families was a deliberate strategy of the Nazis, central to the Holocaust. In September 2025, the World Jewish Restitution Organization reported that most American museums still provided inadequate online information about the ownership histories of objects in their collections, noting that of 160 museums surveyed, only 33 provided satisfactory provenance information on their websites.
