Kommunistische Arbeiders-Partij in Nederland (K.A.P.N., 1921-1932)


In May-July 1921 some 200 oppositional members of the c.p.h. were excluded while others left (see f.i. the Roode Vaan of Barend Luteraan). On 4 September 1921, at Amersfoort, they founded the Kommunistische Arbeiders-Partij in Nederland with ten local sections: Amsterdam, Bussum, Den Haag (The Hague), Deventer, Enschede (published in 1921 its own “De Kommunist”), Hengelo, Leyden (Leiden), Rotterdam, Weesp and Zwolle; with somewhat later, questionable, up to some 400 members, most of whom left within a year leaving no traces. According to the k.a.p.d., in 1922 there would have been some 200 members left, probably less, with sections in Amsterdam, Bussum, Den Haag, Enschede, Leiden, Rotterdam, Utrecht and Zwolle; thus the sections in Deventer, Hengelo and Weesp would have disappeared, while only in Utrecht a new section was founded. The sections outside of Amsterdam left little proof of further activity and thus the members are hard to trace. Also according to the k.a.p.d., in 1922 the Kommunistische Arbeiders-Jeugd (youth-organisation) only had a section in Amsterdam, with some ten members, oriented, in contrast to the great majority of the k.a.p.n.-members, towards the Berlin-Tendency in Germany; some (known members) are included in this list; most of them became participants to the later g.i.c. Although a group carried the name of the party until 1932, it fundamentally fell apart in 1923 when the immediate revolutionary perspective had vanished; and the main task became the clarification of the past movement to prepare for the future, rather than ‘direct action’, which, however, remained important to save lives.

It’s “theoretician” or rather inspirator was Herman Gorter, who wrote or translated all the party’s pamphlets. For “theory”, Herman Gorter relied heavily on Anton Pannekoek’s Weltrevolution und Kommunistische Taktik of August 1920, of which he made his own interpretation (corresponding to the Essen-Tendency in Germany, led by his friend Karl Schröder), in disagreement with Anton Pannekoek, who furthermore never joined the organisation but remained friends with Herman Gorter until the latter’s death in 1927, the year in which Pannekoek started to write again after a quasi-abstinence of six years.

In 1923, finally concluding to a defeat of the proletariat after failed attempts to found a new International (the Communist Workers’ International), which soon broke up into local tendencies, and which Herman Gorter tried in vain to reunify, he more or less retreated also because of serious health problems, writing his famous line “In defeat, I want to be their poet” (end of the first sonnet of The Worker’s Council, published 1931); yet, in the last months of his life he tried to found a new group. Such group came to life only after his death: the g.i.c., far more oriented towards the Berlin-tendency of the German k.a.p.d., if not under the “mentorship” of Anton Pannekoek, at least with his support.

For the following, provisional, very incomplete and certainly disputable list of some 80 members so far identified (some 50 in Amsterdam and over 20 in Overijssel), served the correspondences in the collection of Henk Canne Meijer  in the i.i.s.g.; publications of the k.a.p.n. itself; while good use was also made of some lists electronically available of the Centrale Inlichtingen Dienst ; Dutch secret security police founded in 1919 (1); the whole was completed from civil records (WieWasWie ), indexes of the communal archives of the city of Amsterdam ; some genealogical sites (sometimes very unreliable) and sites on victims of the “final solution” (2); important sources are also: Archieven.nl , and Delpher  (mainly newspapers and periodicals); regional archives also make ever more available on the web, like Collectie Overijssel  and MijnStadMijnDorp  (Overijssel).

Although there were a lot of quarrels, it becomes also clear that it was not just “a bunch of odd-jobbers” [een bende scharrelaars]. Much remains to be desired, so if you dispose of more or better information, please share it.

 — Lubbe, Marinus van der (1909-1934), supposed to have set fire all alone to the German Reichstag building in 1933; he left the c.p.h. in 1931 (maybe somewhat earlier), and thus could not have been a member of the k.a.p.n., and he certainly was not a member of the g.i.c.; he was, however, in contact with the l.a.o. in Leyde (Leiden) and The Hague (Den Haag) and friends with, for instance, Piet van Albada and other g.i.c.-members. He certainly was not an anarchist, although anarchists admired and defended him. His story remains controversial, as he might have been helped by the Nazi’s without his knowledge, although there is no proof whatsoever of such. The Communist Left in the Netherlands was divided; all defended his person against Stalinist and Nazi slander, but not all defended his act; some thought he did it alone, others thought this to be very unlikely.

Jonnie Schlichting, Archiv Karl Roche , wrote us (13 March 2023):
“I saw the documentary – and I really got angry. The historical background is nearly non-existent – nothing on the last four years of the republic when even bourgeois parliamentary democracy was suspended (“Präsidialkabinette”), the 1929 Crash, “Preußenschlag” 1932. And another favourite of mine: the so called “Spartacus-Aufstand” January 1919 was initiated by Moscow …
Hindenburg’s role: a senile old man, the last bulwark of democracy, only weakly resisting Hitler? Nothing on the role of the s.p.d. in the republic, its collaboration with the old powers during the revolution 1918-1919; what did they do while governing Prussia? The “Berliner Blutmai 1929”. The s.p.d. only appears in the end when boycotting the Reichstags opening in the Kroll-Oper, but Wels’ speech against the “Ermächtigungsgesetz” – at least one small gesture of resistance – is missing. Oh, and here it is again, the word: “Machtergreifung”.
The background of van der Lubbe is missing; yes, they only know Münzenbergs “Braunbuch” (at least not used completely uncritically – at least).
And formally: the re-coloured old Wochenschau clips and photos – why? And they mixed – without giving notice – scenes from the d.e.v.a. movie with original material. This is lousy!
There are some impressive moments, I must confess, the parts in court, the pictures of the drugged Rinus van der Lubbe – and even Dimitrow leading Goering on the nose ring.
But as a whole this docu is waisted money on the edge of falsifying history. You have to know much more about the history and times than the film makers seem to do. – Not fit for children and people without good historical knowledge.”

Editorial Notes

1. The central archives of the c.i.d.  were destroyed in the May-days of 1940; only dispersed sources survived; the former ennemies of the state, in 1940, were considered potentially usefull against a common ennemy. The lists of “left-extremists” however circulated on many places and were certainly used by the German authorities.

2. See particularly: Joods Monument ; no definition is given whatsoever of who was supposed to have been a “jew” other than in the eyes of the nazi’s; in 1940 the German authorities imposed a “jew” identity on more than half of the former k.a.p.n. members, many of them (and their families) were murdered; for the workers’ revolt against the deportations of “jews” (whatever their background), see particularly: De Februari-staking 25-26 februari 1941 / B.A. Sijes. – ’s-Gravenhage : Martinus Nijhoff, 1954.
