The Polish underground press drew on experiences of Second World War veterans of Armia Krajowa and much attention was paid to conspiracy; however, after martial law in Poland and the government crackdown on Solidarity, the activities of underground publishing were significantly curtailed for several years. Nevertheless, with the communist government losing power in the second half of the 1980s, production of Polish underground printing ("bibuła") dramatically increased, and many publications were distributed throughout the entire country. After the Revolutions of 1989 some of the underground publishers in Poland transformed into regular and legal publishing houses.
