The article outlines the history of one of the longest running underground periodicals in Kraków. 'Dziennik Polski' was published by the Democratic Party and, from 1943, by the Polish Democracy Party. Issues discussed include the composition of subsequent editorial teams, editors (e.g. F. M. Arczynski), changes in title and editorial offices, the distribution system. 613 issues were analysed for identification of the paper's political agenda, which was found to undergo a shift towards radicalism. The initial support for the émigré government turned into criticism of its concept and vision of the independent Poland.
