The Polish anti-religious campaign was initiated by the communist government in Poland which, under the doctrine of Marxism, actively advocated for the disenfranchisement of religion and planned atheisation. To this effect the regime conducted anti-religious propaganda and persecution of clergymen and monasteries. As in most other Communist countries, religion was not outlawed as such (an exception being Albania) and was permitted by the constitution, but the state attempted to achieve an atheistic society.
