Blutmai


Blutmai refers to several days of rioting by Communist Party of Germany supporters in early May 1929 that led to violence between the communist demonstrators and members of the Berlin Police which was under the control of the Social Democratic Party of Germany. In defiance of a ban on public gatherings in Berlin the KPD organized a rally to celebrate May Day. Although fewer supporters showed than what the KPD hoped, the response by the Berlin Police was immediate and harsh, with police using firearms against mostly unarmed civilians. During the three days of rioting 33 civilians were killed and over a thousand would be taken into police custody. The event would be a significant moment in the decline of the Weimar Republic and its political stability. The incident also marked a turning point in relations between the center-left SPD government and the far-left Moscow-aligned KPD, weakening any prospect of a united left-wing opposition to fascism and the rising National Socialist German Workers Party. Criticisms of the severity of the police response also led to a further erosion of public trust in the government.

Background

The Social Democratic Party had emerged with the largest number of seats in the Reichstag from the 1928 German federal election, with 153 of the 491 seats. This victory was due to its leading position in the Weimar Coalition and the politically liberal, economically prosperous Golden Twenties. Due to its coalition agreements with centrist and even right-wing parties, however, the extent to which it could pursue meaningful reforms addressed at labor relations and workers' rights were curtailed. The KPD, meanwhile, remained one of the largest and most politically potent communist parties in Europe and actually saw its total number of seats increase in the 1928 election from 45 to 54. The KPD was led by Ernst Thälmann, who supported a close orientation with the Soviet Union and the Communist International. At the time, the dominant position supported by Moscow was that social democracy was a form of social fascism that frustrated rather than helped the proletariat. Accordingly, the KPD under Thälmann pursued a hostile, confrontational position toward the SPD as defenders of the capitalist status quo. This perception was encouraged by numerous anti-communist SPD politicians in the German and Prussian governments, including Chancellor Hermann Müller, Interior Minister Carl Severing, Prussian Prime Minister Otto Braun, Prussia Interior Minister Albert Grzesinski, and Berlin police chief Karl Zörgiebel.
Despite its ideals of democracy and liberalism, the Weimar Republic had acquired heavily militaristic state institutions accustomed to using repressive methods from its authoritarian predecessor. The Berlin Police used military-style training methods and was criticized both for its reactionary culture and acquisition of infantry weapons and equipment. The police were regularly involved in political violence throughout the 1920s, including against communist dissidents. This led to a willingness among the Berlin Police to use a "a military advantage to inflict a decisive defeat on the 'proletarian enemy.'"
, on April 29, 1929: "200 Dead on May 1? The Criminal Plans of the Communists"
The KDP had a paramilitary wing, the Roter Frontkämpferbund, which had a history of clashing with police. Like the Nazi Sturmabteilung, the RFB operated in small mobile fighting squads trained in street fighting. In late 1928 four people had died in fights between paramilitary groups. In December 1928 Zörgiebel issued a ban on open-air gatherings in Berlin, citing a recent stabbing involving RFB members. The ban also appeared to affirm the official communist party line that capitalism had entered its Third Period and therefore the state would become more draconian in obstructing efforts to organize the proletariat.
In the lead-up to the 1929 celebration of International Workers' Day on the first of May, KPD-affiliated newspapers urged members and sympathizers to take to the streets. The KPD urged workers to defy the ban and organize peacefully, but to be prepared to strike on May 2 "if Zörgiebel dares to spill workers' blood." The newspaper Die Rote Front stressed "the sharpened movement of the power organs of the capitalist State against the proletariat" in describing potential police violence against communists. The SPD newspaper Vorwärts reported SPD politician Franz Künstler's belief that the KPD was seeking to intentionally sacrifice supporters' lives, saying the party would have to "reckon with" 200 dead. SPD support for the ban, however, was not unanimous, given the irony of a social democratic government preventing public gatherings on an international holiday for working men and women. Meanwhile, the National Socialist newspaper Der Angriff'' declared in April 1929 that the SPD and KPD fighting among themselves represented a "favorable wind" for the Nazi Party.

Riots of May 1-3

On May 1 the KPD failed to organize a showing greater than normal, the majority of demonstrators coming from communist strongholds in northern and eastern Berlin. Most businesses operated normally. SPD-affiliated trade unions held their own peaceful, well-attended meetings in closed assemblies. The Berlin Police, however, still responded in force to the open-air gatherings, with flying squads arriving in trucks and attacking any civilians with truncheons where any demonstration was reported. When the lawful indoor conventions dispersed and people took to the streets for home, the police arrested people merely because they found themselves on the incorrect side of a police checkpoint or were caught up in fleeing a police sortie. Law enforcement handled the defiance of the ban as if it were the popular revolt the communist press had called for, rather than the confused and haphazard act of civic disobedience that it truly was.
The police soon cleared the streets in central Berlin. In the Wedding district, home to many communist supporters, police violence gradually escalated into persistent street combat, including civilians erecting barricades. The Berlin Police began to use firearms, and one of the first victims killed was a man who was watching from his window. The police would later be criticized for not warning about shooting on sight. Two other victims were shot through doors, including an 80-year-old man in his apartment. Most of the fighting was limited to Kösliner Street in Wedding and by midnight most of the area was under police control. In the southeast, in the Neukölln district around the Hermannstrasse, the rioting would last into the evening, with the police using personnel carriers and armored cars, occasionally aiming their weapons at residences.

On May 2 Severing met with Grzesinski and Prussian Prime Minister Braun. They immediately banned the primary German communist newspaper Die Rote Fahne, both as a consequence of its incitement but also to hinder news spreading of the high civilian casualties. In the Reichstag, KPD politician Wilhelm Pieck condemned Zörgiebel as a "common murderer." The KPD had called for a general strike on May 2 in response to the police violence, but as with the May Day turnout, this was met with limited success. The KPD claimed 25,000 people went on strike in Berlin on May 2, 3, and 4 and an additional 50,000 walked out in sympathy throughout Germany.
The RFB, previously operating underground in fear of outright proscription, joined the rioting in Wedding during the afternoon of May 2, once more constructing barricades in largely spontaneous defensive actions. Gunfire was exchanged between the communist militants and the police in the streets. Contemporary police and media accounts depict a balanced urban battle between both sides, although modern scholars dispute this. For example, the Berlin Police attacked Kösliner Street from both ends, giving the perception gunfire was coming from each side of the barricades. The police also enforced a general curfew, leading to confused confrontations in the darkness. Finally, the communists were not as armed or prepared as the police, some having looted a hardware store for starting pistols that sounded like firearms but fired no bullets.
By the afternoon of May 3 the fighting had ended and on May 6 the Berlin Police lifted martial law in the Wedding and Neukölln districts. Grzesinski extended the ban on the RFB from Berlin to all of Prussia; by May 15 the RFB and its youth wing, the Rote Jungfront, were illegal throughout the country. Police conducted house-to-house searches in Wedding and made further arrests, heightening the political tension produced by the riots. By this point the harsh police suppression had led to a full furor in the Reichstag and the Prussian Diet, with heavy media coverage by independent and partisan newspapers.

Aftermath

It was determined that over thirty people were killed, all civilians, and all by police firearms save for one individual struck by a speeding police van. Around 200 were injured and approximately 1,200 were arrested, with only 44 imprisoned. Eight of the civilians killed were women and nineteen were Wedding residents. Of the first 25 victims, two were SPD members and seventeen belonged to no party; none were KPD members. Most police reports stated the identity of the killer was unknown. Police found no evidence that the demonstrators who took to the streets were prepared for armed insurrection, with the house-to-house search in Wedding producing mostly souvenirs from World War I.
A little over a month after the riots the KPD held its Twelfth Party Congress in Berlin. It passed a resolution calling the rioting "a turning-point in political developments in Germany... The preconditions are appearing for the approach of an immediately revolutionary situation, with the development of which the armed uprising must inevitably step onto the agenda." The KPD deepened their commitment to opposing the SPD as a fascist institution who would use instruments of the state against them. Yet there was less recognition that the KPD had failed to muster the sort of national or even local influence in Berlin to actually launch a rebellion of credible danger to the status quo. The rioting had been less motivated by KPD clamoring as it was a more or less spontaneous reaction to the heavy-handed police tactics, even if the neighborhoods in question were occupied predominately by communists.
The SPD had their equivalent of the "social fascism" perspective in its leaders' anxieties over a new Spartacist uprising. Although the KPD did desire to overthrow the Weimar Republic, extremist parties did not have the same appeal they would enjoy after the Great Depression of 1929 hit Germany. The SPD government considered the KPD more of a threat than the Nazi Party, as evidenced by Grezesinski lifting a ban on Adolf Hitler speaking publicly in September 1928. "Hysterical assessments" by SPD politicians of the threat posed by the KPD combined with the militant nature of the Berlin police meant that conflict and even violence between the two groups was probable if not inevitable.
