The study is devoted to the problem of the presence of Polish authors from the ranks of the opposition, poets, writers and philosophers (Czesław Miłosz, Leszek Kołakowski) in Czech and Slovak samizdats. The publications from the environment of the Czech and Slovak political opposition presented not only domestic authors, but also the work of foreign writers including Poles. This testifies to their great organizational and editorial possibilities, enabling a relatively extensive pre-sentation of authors from other states of the so-called Soviet Bloc.
