The vast majority were recent immigrants to Belgium who had fled persecution in Germany and Eastern Europe, and, as a result, only a small minority actually possessed Belgian citizenship.
Some were helped by the organized resistance, such as the Comité de Défense des Juifs (CDJ; "Committee of Jewish Defense"), which provided food and refuge to hiding Jews.
These were chiefly represented by the Vlaams Nationaal Verbond (VNV; "Flemish National Union") and Verdinaso in Flanders, and Rex in Wallonia.
Both Flemish parties supported the creation of an ethnically Germanic "Dietse Natie" ("Greater Dutch State") from which Jews would be excluded.
[6] Their stance was officially condemned by the Belgian authorities, but prominent figures, including King Leopold III, were suspected of holding anti-Semitic attitudes.
[7] From June 1938, Jewish illegal immigrants arrested by the Belgian police were deported to Germany, until public condemnation halted the practice after Kristallnacht in November 1938.
[8] Between 1938 and the start of the war, with the influence of Fascist parties declining in Belgium, the country began accepting more Jewish refugees, including 215 from the MS St. Louis who had been refused visas elsewhere.
In July 1944, the Militärverwaltung was replaced with a civilian administration (Zivilverwaltung), greatly increasing the power of the more radical Nazi Party and SS organisations until the Allied liberation in September 1944.
[20] The AJB, closely supervised by the SiPo-SD (Sicherheitspolizei und Sicherheitsdienst; "Security Police and Intelligence Service"), was also responsible for the administration of the transit camp at Mechelen.
[20] The AJB played a major role in persuading Jews to turn up voluntarily for deportation, though whether they knew the fate awaiting the deportees is disputed.
[18] On 14 April 1941, after watching the German propaganda film Der Ewige Jude, Flemish paramilitaries from the Volksverwering, VNV and Algemeene-SS Vlaanderen began a pogrom in the city of Antwerp.
[22] The Belgian version of the badge depicted a black letter "J" (standing for "Juif" in French and "Jood" in Dutch) in the centre of a yellow star of David.
[22] At great personal risk, the Belgian civil authorities in Brussels and Liège refused to distribute the badge, buying time for many Jews to go into hiding.
[23] The German authorities in Antwerp attempted to enforce the wearing of badges in 1940, but the policy was dropped when non-Jewish citizens protested and wore the armbands themselves.
[26] In September, armed Devisenschutzkommando (DSK; "Currency protection command") units raided homes to seize valuables and personal belongings as the occupants were preparing to report to the transit camp, and in the same month, Jews with Belgian citizenship were deported for the first time.
[34] The German occupation authorities made use of the surviving infrastructure of the pre-war state including the Belgian civil service, police and Gendarmerie.
[35] Belgian resistance to the treatment of Jews crystallised between August–September 1942, following the passing of legislation regarding wearing yellow badges and the start of the deportations.
[15] The first organization specifically devoted to hiding Jews, the Comité de Défense des Juifs (CDJ-JVD), was formed in the summer of 1942.
[27] In the evening of 19 April 1943, three poorly armed members of the resistance attacked the railway convoy as it passed near Haacht in Flemish Brabant.
[37] Resistance members used a lantern covered with red paper (a danger signal) to stop the train, and freed 17 prisoners from one wagon before they were discovered by the Germans.
In June 1942, the representative of the German Foreign Ministry in Brussels, Werner von Bargen, complained the Belgians did not exhibit "sufficient understanding" of Nazi racial policy.
As early as October 1940, the senior Catholic clergyman in Belgium, Cardinal Jozef-Ernest van Roey, condemned the German policy and particularly the legislation from 1942.
The Committee of Secretaries-General, a panel of Belgian senior civil servants tasked with implementing German demands, refused from the outset to enforce anti-Jewish legislation.
[46] In June 1942, a conference of the 19 mayors of the Greater Brussels region refused to allow its officials to distribute yellow badges to Jews in their districts.
[23] At great personal risk, the mayors, led by Joseph Van De Meulebroeck, sent a letter protesting the decree to the German authorities on 5 June.
[23] The refusal of Brussels' council, and later that of the city of Liège, to distribute badges allowed many Jews to go into hiding before the deportations began.
She appealed to the Military Governor of Belgium, General Alexander von Falkenhausen, who sent Eggert Reeder, his deputy and head of the non-military aspects of the administration, to Berlin to clarify the policy with Reichsführer-SS Heinrich Himmler.
The SS-Reichssicherheitshauptamt (RSHA; "Reich Main Security Office") made concessions to Elisabeth, allowing Jews with Belgian citizenship to be exempt from deportation, and Jewish families would not be broken up.
[50] Breendonk and Dossin Barracks (at the site of the former Mechelen transit camp) are preserved as museums to the Holocaust and to German repression in Belgium during the occupation.
[52] As of 2013, a total of 1,612 Belgians have been awarded the distinction of Righteous Among the Nations by the State of Israel for risking their lives to save Jews from persecution during the occupation.
