Laufenberg was part of the faction within the USPD which left to establish the
Communist Party of Germany (KPD) and before long the local party had come under the control of Laufenberg and his ally
Fritz Wolffheim. The pair had been strong critics of German imperialism: in 1915 they had produced a pamphlet against German expansionism and attacking the SPD for being, as they saw it, complicit in such aggression. Following the war, in October 1919, the pair made contact with
Karl Radek and suggested a policy to him that they were already calling 'National Bolshevism'). They sought a
dictatorship of the proletariat which would harness German
nationalism and place the country back on a war footing against the occupying
Allied armies in alliance with the
Soviet Union. The idea initially met with some enthusiasm amongst members of the
Spartacus League. Such support soon ebbed however when
Vladimir Lenin publicly denounced the policy, claiming that Laufenberg was seeking a war coalition with the German
bourgeoisie, before branding him as "absurd". Radek, after showing initial enthusiasm, soon also denounced Laufenberg's National Bolshevism vehemently. ==Later years==
