Following their invasion of Denmark in 1940, the Germans did not confiscate the population's radios, removing much of the need for underground media. Only with the 1941 banning of the Communist Party of Denmark did a significant underground press emerge, with the illegal continued publishing of the Communist Party's paper "Land og Folk". At its height, "Land og Folk" reached a circulation of 130,000, and was the largest underground newspaper in Denmark throughout the German occupation. In respectively December 1941 and April 1942 the major bipartisan papers "De Frie Danske" and "Frit Danmark" followed. In all some 600 different underground papers were published in Denmark.
