The Holocaust in Belgium The Holocaust in German - occupied Belgium refers to the persecution and attempted extermination of Jews and Roma between 1940 and 1944 during World War II . At the start of the war , the population of Belgium was overwhelmingly Catholic . Jews made up the largest non - Christian population in the country , numbering between 70 – 75 , 000 out of a population of 8 million . Most lived in the cities of Antwerp , Brussels , Charleroi and Liége . The vast majority of were recent immigrants to Belgium fleeing persecution in Germany and Eastern Europe and , as a result , only a small minority actually possessed Belgian citizenship . Shortly after the invasion of Belgium , the Military Government passed a series of anti - Jewish laws in October 1940 . The Belgian Committee of Secretary - Generals refused from the start to co - operate on passing any anti - Jewish measures and the Military Government seemed unwilling to pass further legislation . The German government began to seize Jewish - owned businesses and forced Jews out of positions in the civil service . In April 1941 , without orders from the German authorities , Flemish collaborators pillaged two synagogues in Antwerp and burned the house of the chief rabbi of the town in the Antwerp Pogrom . The Germans created a in the country , the ( AJB ; " Association of Jews in Belgium " ) , which all Jews were required to join . As part of the Final Solution from 1942 , the persecution of Belgian Jews escalated . From May 1942 , Jews were forced to wear yellow Star of David badges to mark them out in public . Using the registers compiled by the AJB , the Germans began deporting Jews to concentration camps in the General Government ( the occupied portion of Poland ) . Jews chosen from the registration lists were required to turn up at the newly established Mechelen transit camp ; they were then deported by train to concentration camps , mostly to Auschwitz . Between August 1942 and July 1944 , around 25 , 000 Jews and 350 Roma were deported from Belgium ; more than 24 , 000 were killed before the camps were liberated by the Allies . From 1942 , opposition among the general population to the treatment of the Jews in Belgium grew . By the end of the occupation , more than 40 per cent of all Jews in Belgium were in hiding ; many of them were hidden by Gentile s , particularly by Catholic priests and nuns . Some were helped by the organized resistance , such as the ( CDJ ; " Committee of Jewish Defence " ) , which provided food and refuge to hiding Jews . Many of the Jews in hiding joined the armed resistance . In April 1943 , members of the CDJ attacked the twentieth rail convoy to Auschwitz and succeeded in rescuing some of those being deported . Background . Religion and anti - Semitism . Before the war , the population of Belgium was overwhelmingly Catholic . Around 98 per cent of the population was baptized and around 80 per cent of marriage ceremonies were held with traditional Catholic services , while politically the country was dominated by the Catholic Party . The Jewish population of Belgium was comparatively small . Out of a population of around 8 million , there were only 10 , 000 Jews in the country before World War I . The interwar period saw substantial Jewish immigration to Belgium . By 1930 , the population rose to 50 , 000 , and by 1940 it was between 70 , 000 – 75 , 000 . Most of the new Jewish immigrants came from Eastern Europe and Nazi Germany , escaping anti - Semitism and poverty in their native countries . Few of the Jewish migrants claimed Belgian citizenship , and many did not speak French or Dutch . Jewish communities developed in Charleroi , Liége , Brussels and , above all , Antwerp , where more than half of the Jews in Belgium lived . The Interwar period also saw the rise in popularity of Fascist New Order parties in Belgium . These were chiefly represented by the ( VNV ; " Flemish National Union " ) and in Flanders , and in Wallonia . Both Flemish parties supported the creation of an ethnically Germanic " " ( " Greater Dutch State " ) , in which Jews would be excluded . , whose ideology was based on Christian Fascism , was particularly anti - Semitic , but both VNV and campaigned under anti - Semitic slogans for the 1938 elections . Their stance was officially condemned by the Belgian authorities , but prominent figures , including King Leopold III , were suspected of holding anti - Semitic attitudes . From June 1938 , Jewish illegal immigrants arrested by the Belgian police were deported to Germany , until public condemnation halted the practice after in November 1938 . 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 who had been refused visas elsewhere . German invasion . In the interwar period , Belgium followed a strict policy of political neutrality . Though the Belgian Land Component was mobilized in 1939 , the country only became involved in the war on 10 May 1940 , when it was invaded by Nazi Germany . After a campaign lasting 18 days , the Belgian military , along with its commander - in - chief King Leopold III , surrendered to Germany on 28 May . Belgium , together with the French province of Nord - Pas de Calais , were grouped together under the German Military Administration in Belgium and Northern France . The Military Government formed part of the ( rather than Nazi Party or SS ) , and was therefore commanded by the military ( OKW ; " " Wehrmacht " High Command " ) . The Holocaust . Early discrimination and persecution . On 23 October 1940 , the German Military Administration adopted anti - Jewish legislation for the first time . The new laws , similar to the Nuremberg Laws adopted in Germany in 1935 , coincided with the adoption of similar legislation in the Netherlands and in France . The laws of 28 October forbade Jews to practice certain professions ( including the civil service ) and forced Jews to register with their local municipality . On the same date , the German administration announced a definition of who was regarded as Jewish . Jewish - owned shops or businesses had to be marked by a sign in the window , and Jewish - owned economic assets had to be registered . From June 1940 , a list of Jewish businesses had already been drawn up in Liége . In 1940 , the German government began to liquidate Jewish businesses . Some were transferred to German ownership in a process termed Aryanization . Some 6 , 300 Jewish - owned businesses were liquidated before 1942 , and 600 were Aryanized . Around 600 million Belgian francs was raised from the seizures , much less than anticipated . In total , between 28 October 1940 and 21 September 1942 , 17 anti - Jewish ordinances were proclaimed by the Military Administration . " Association des Juifs en Belgique " . The " Association of Jews in Belgium " ( AJB ) was a created by the Germans to administer the Jewish population of Belgium from November 1941 . Though directed by the Germans , the AJB was run by Jews and acted as an " organizational ghetto " , allowing the Nazis to deal with Belgian Jews as a unit . The AJB played a major role in registering Jews in the country . In total , 43 , 000 Jews were registered with the AJB . This number represents only half of the total Jewish population , reflecting the community ' s mistrust of the organization , but it was the figure that Adolf Eichmann presented as the total number of Jews in Belgium at the Wannsee Conference in January 1942 . During the deportations , around 10 , 000 Jews were arrested based on their affiliation to the AJB . The AJB , closely supervised by the ( " Sicherheitspolizei und Sicherheitsdienst " ; " Security Police and Intelligence Service " ) , was also responsible for the administration of the transit camp at Mechelen . 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 . From 1942 , following the assassination by the Resistance of Robert Holzinger , an AJB leader , confidence in the association declined and it was regarded with increasing suspicion . After the war , the leaders of the AJB were tried and acquitted of complicity in the Holocaust . Antwerp Pogrom . On 14 April 1941 , after watching the German propaganda film , Flemish paramilitaries from the , VNV and began a pogrom in the city of Antwerp . The mob , armed with iron bars , attacked and burned two synagogues in the city and threw the Torah scrolls onto the street . They then attacked the home of Marcus Rottenburg , the town ' s chief rabbi . The police and fire brigade were summoned , but they were forbidden to intervene by the German authorities . Yellow badge . As in the rest of occupied Europe , compulsory wearing of the yellow badge was enforced from 27 May 1942 . 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 . The star had to be displayed prominently on all outer clothing when in public and there were harsh penalties for non - compliance . The decree sparked public outrage in Belgium . At great personal risk , the Belgian civil authorities in Brussels and Liége refused to distribute the badge , buying time for many Jews to go into hiding . 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 . Deportation and extermination . From August 1942 , the Germans began deporting Jews , using ( " recruitment for work " ) in German factories as a pretext . Around half of the Jews turned up voluntarily ( though coerced by the German authorities ) for transportation . Later in the war , the Germans increasingly relied on the police to arrest or round up Jews by force . The first convoy left Mechelen transit camp on 22 July 1942 , although nearly 2 , 250 Jews had been deported as forced laborers for , a civil and military engineering group , which was working on the construction of the Atlantic Wall in Northern France . Between October 1942 and January 1943 , deportations were temporarily halted ; by this time 16 , 600 people have been deported on 17 rail convoys . As the result of Queen Elizabeth ' s intervention with the German authorities , all of those deported in this first wave were not Belgian citizens . In 1943 , the deportations resumed . In September , armed ( 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 . DSK units relied on networks of informants , who were paid between 100 and 200 Belgian francs for each person they betrayed . After the war , the collaborator Felix Lauterborn stated in his trial that 80 per cent of arrests in Antwerp used information from paid informants . In total , 6 , 000 Jews were deported in 1943 , with another 2 , 700 in 1944 . Transports were halted by the deteriorating situation in occupied Belgium before the liberation . The percentages of Jews which were deported varied by location . It was highest in Antwerp , with 67 per cent deported , but lower in Brussels ( 37 per cent ) , Liége ( 35 per cent ) and Charleroi ( 42 per cent ) . The main destination for the convoys was Auschwitz concentration camp in occupied Poland . Smaller numbers were sent to Buchenwald and Ravensbrück concentration camp s , as well as Vittel concentration camp in France . In total , 25 , 437 Jews were deported from Belgium . Only 1 , 207 of these survived the war . Amongst those deported and killed was the surrealist artist Felix Nussbaum in 1944 . Belgian collaboration in the Holocaust . Members of Belgian fascist political parties actively attempted to assist in the deportation of Jews . The VNV and encouraged the deportations , while an association known as / ( " The People ' s Defence " ) was specially formed to bring together Belgian anti - Semites and to assist in the deportations . During the early stages of the occupation , they campaigned for harsher anti - Jewish laws . Both and the VNV routinely published anti - Semitic articles in their party newspapers . Although the Belgian civil authorities ( especially the police and security service ) were officially forbidden to assist the German authorities in anything other than routine maintenance of order , several incidents occurred where individual policemen or police sections assisted in the German arrest of Jews , against orders . In Antwerp , the Belgian authorities facilitated the conscription of Jews for forced labour in France in 1941 and aided in the rounding up of Jews in August 1942 after the threatened to imprison local officials in Breendonk . Outside Antwerp , the Germans used coercion to force the Belgian police to intervene , and in Brussels at least three police officers disobeyed orders and helped arrest Jews . The historian Insa Meinen argued that around a fifth of the Jews arrested in Belgium were rounded up by the Belgian police . Nevertheless , the general refusal of the Belgian police to assist in the Holocaust has been cited as a reason for the comparatively high survival rate of Belgian Jews during the Holocaust . Belgian opposition to Jewish persecution . 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 . When deportations began , Jewish partisans destroyed records of Jews compiled by the AJB . The first organization specifically devoted to hiding Jews , the ( CDJ ) , was formed in the summer of 1942 . The CDJ , a left - wing organization , may have saved up to 4 , 000 children and 10 , 000 adults by finding them safe hiding places . It produced two Yiddish language underground newspapers , ( " Our Word " , with a Labour - Zionist stance ) and ( " Our Fight " , with a Communist one ) . The CDJ was only one of dozens of organised resistance groups that provided support to hidden Jews . Other groups and individual resistance members were responsible for finding hiding places and providing food and forged papers . Many Jews in hiding went on to join organised resistance groups . Groups from left wing backgrounds , like the ( FI - OF ) , were particularly popular with Belgian Jews . The Communist - inspired ( PA ) had a particularly large Jewish section in Brussels . The resistance was responsible for the assassination of Robert Holzinger , the head of the deportation program , in 1942 . Holzinger , an active collaborator , was an Austrian Jew selected by the Germans to head the deportation program . The assassination led to a change in leadership of the AJB . Five Jewish leaders , including the head of the AJB , were arrested and interned in Breendonk , but were released after public outcry . A sixth was deported directly to Auschwitz . The Belgian resistance was unusually well informed on the fate of the deported Jews . In August 1942 ( two months after the start of the Belgian deportations ) , the underground newspaper reported that " They [ the deported Jews ] are being killed in groups by gas , and others are killed by salvos of machinegun fire . " In early 1943 , the sent Victor Martin , an academic economist at the Catholic University of Louvain , to gather information on the fate of deported Belgian Jews using the cover of his research post at the University of Cologne . Martin visited Auschwitz and witnessed the crematoria . Arrested by the Germans , he escaped , and was able to report his findings to the CDJ in May 1943 . Attack on the 20th transport . The best - known Belgian resistance action during the Holocaust was the attack on the 20th rail convoy to Auschwitz . 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 . The train , containing over 1 , 600 Jews , was guarded by 16 Germans from the . 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 . A further 200 managed to jump from the train later in the journey , as the train ' s Belgian driver deliberately kept his speed low to allow others to escape . All three resistance members responsible for the attack were arrested before the end of the occupation . Youra Livchitz was executed and Jean Franklemon and Robert Maistriau were deported to concentration camps but survived the war . The attack on the 20th train was the only attack on a Holocaust train from Belgium during the war , as well as the only transport from Belgium to experience a mass breakout . Passive resistance . The treatment of Jews by the Germans led to public resistance in Belgium . 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 . The Belgian underground newspaper called for Belgian citizens to make small gestures to show their disgust at the Nazi racial policy . In August 1942 , the paper called for Belgians to " Greet them [ the Jews ] in passing ! Offer them your seat on the tram ! Protest against the barbaric measures that are being applied to them . That ' ll make the " Boches " furious ! " Discrimination against Jews was condemned by many high - profile figures in the occupied country . 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 . Van Roey made many of the church ' s resources available for hiding Jews , but was prevented from publicly condemning the treatment of the Jews by his peers , who feared a Nazi repression of the Church . German attempts to involve the Belgian authorities and local government in its implementation began to arouse protest from 1942 . The Committee of Secretary - Generals , a panel of Belgian senior civil servants tasked with implementing German demands , refused from the outset to enforce anti - Jewish legislation . 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 . 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 . The refusal of Brussels ' council , and later that of the city of Liége , to distribute badges allowed many Jews to go into hiding before the deportations began . In the same year , members of the AJB met with Queen Elizabeth to appeal for her support against the deportations . 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 Heinrich Himmler . The ( RSHA ; " Reich Main Security Office " ) made concessions to Elizabeth , allowing Jews with Belgian citizenship to be exempt from deportation , and Jewish families would not be broken up . The RSHA also agreed not to deport Jewish men over the age of 65 and women over 60 , after Belgian protests that they would be too old to be used as forced labor . Legacy and remembrance . In the aftermath of the war , emigration to Israel further decreased the Jewish population of Belgium , which as of 2011 was estimated at between 30 , 000 and 40 , 000 . The population is still concentrated in Brussels and Antwerp , but new smaller communities ( such as Ghent , Knokke , Waterloo and Arlon ) have developed since 1945 . Notable Belgian Holocaust survivors include François Englert , a joint recipient of the Nobel Prize in Physics in 2013 , and Paul Lévy , a well - known journalist who was also responsible for the design of the European flag . Since the passing of the Holocaust denial law in 1995 , it is illegal to deny or attempt to justify the Holocaust . The act follows the Belgian Anti - Racism Law , passed in 1981 , which led to the establishment of the Centre for Equal Opportunities and Opposition to Racism , which researches racism and anti - Semitism in Belgium as well as aiding victims of discrimination . Fort 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 . In 2004 , the Belgian Senate commissioned the Centre for Historical Research and Documentation on War and Contemporary Society ( Cegesoma ) to produce a definitive historical report on Belgian collaboration in the Holocaust . The report , entitled " Docile Belgium " ( / ) , was published in 2007 . It generated significant public interest in Belgium and abroad . The report ' s findings were controversial , as they emphasised the extent to which the Belgian police and authorities had collaborated in the deportation of Jews . 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 .
