The political situation in Germany and elsewhere in Europe after World War I (1914–1918) contributed to the rise of virulent antisemitism. Many Germans did not accept that their country had been defeated, which gave birth to the stab-in-the-back myth. This insinuated that it was disloyal politicians, chiefly Jews and communists, who had orchestrated Germany's surrender. Inflaming the anti-Jewish sentiment was the apparent over-representation of Jews in the leadership of communist revolutionary governments in Europe, such as Ernst Toller, head of a short-lived revolutionary government in Bavaria. This perception contributed to the canard of Jewish Bolshevism.
The German view of the Roma as hereditary criminals and "asocials" was reflected in their classification in the concentration camps, where they were usually counted among the asocials and given black triangles to wear. According to Niewyk and Nicosia, at least 130,000 died out of nearly one million in German-occupied Europe. The United States Holocaust Memorial Museum calculates at least 220,000. Ian Hancock, who specializes in Romani history and culture, argues for between 500,000 and 1,500,000. The treatment of the Roma was not consistent across German-occupied territories. Those in France and the Low Countries were subject to restrictions on movement and some confinement to collection camps, while those in Central and Eastern Europe were sent to concentration camps and murdered by soldiers and execution squads. Before being sent to the camps, the Roma were herded into ghettos, including several hundred into the Warsaw Ghetto. Further east, teams of Einsatzgruppen tracked down Romani encampments and murdered the inhabitants on the spot, leaving no records of the victims. After the Germans occupied Hungary, 1,000 Roma were deported to Auschwitz.[x]
Pogroms occurred in several countries occupied by, or supportive of, Germany, attacks that were both encouraged by the Germans and carried out without their involvement. Thousands of Jews were killed in January and June 1941 in the Bucharest pogrom and Iaşi pogrom in Romania, a German ally. According to a 2004 report written by Tuvia Friling and others, up to 14,850 Jews died during the Iaşi pogrom. The Romanian military killed up to 25,000 Jews in Odessa, then under Romanian control, between 18 October 1941 and March 1942, assisted by gendarmes and the police. Mihai Antonescu, Romania's deputy prime minister, is reported as saying it was "the most favorable moment in our history" to solve the "Jewish problem". In July 1941 he said it was time for "total ethnic purification, for a revision of national life, and for purging our race of all those elements which are foreign to its soul, which have grown like mistletoes and darken our future".
In anticipation of such violence against the Jews by the Nazis, President Franklin D. Roosevelt had invited 32 countries to a Conference in Evian, France in July 1938 to discuss the problem of Jewish refugees. The only country which agreed to allow Jewish refugees as immigrants was the Dominican Republic; 5,000 German Jews emigrated to the Dominican Republic before the start of World War II. The American Congress refused to change the US immigration laws, passed in 1920 and 1921, to allow a higher quota of Jewish refugees from Germany to enter, although America did start filling the quota under the existing laws for the first time.
The camp was liberated on April 15, 1945, by the British 11th Armoured Division. The soldiers discovered approximately 60,000 prisoners inside, most of them half-starved and seriously ill, and another 13,000 corpses, including those of Anne and Margot Frank, lying around the camp unburied. The horrors of the camp, documented on film and in pictures, made the name "Belsen" emblematic of Nazi crimes in general for public opinion in many countries in the immediate post-1945 period. Today, there is a memorial with an exhibition hall at the site.
