Workers Party of the Netherlands (build-up organisation)

The Workers Party of the Netherlands (build-up organisation) (Dutch: Arbeiderspartij van Nederland (opbouworganisatie), APN(o)) was a small, orthodox Marxist-Leninist political organisation in the Netherlands active from the late 1970s to the early 1980s. It was a so-called "build-up organisation" (Dutch: opbouworganisatie), meaning it focused on establishing a presence within the working class and laying the groundwork for a future revolutionary party, rather than immediately contesting elections.

The APN(o) emerged from a split within the Communist Workers' Organisation of the Netherlands (KMAN) in the late 1970s. The split revolved around disagreements on strategy and tactics, particularly regarding the role of the party in relation to the working class and the broader political landscape. The APN(o) advocated for a more concentrated effort on organising within factories and workplaces, focusing on building a strong base of support among industrial workers.

The organisation adhered to a Maoist ideology, advocating for a socialist revolution based on the principles of Marxism-Leninism-Mao Zedong Thought. They viewed the Soviet Union as revisionist and a social-imperialist power.

The APN(o) was never a significant force in Dutch politics and remained a relatively small group throughout its existence. They engaged in activities such as distributing leaflets, participating in demonstrations, and attempting to organise workers in specific industries. The organisation ultimately dissolved in the early 1980s, with its members dispersing into other political groups or withdrawing from political activity altogether. The APN(o) is primarily notable as a small example of the fragmented far-left landscape that existed in the Netherlands during that period.
