Vatican and Catholics in Russia in 1920 - 1930: Communication Problems

The paper is concerned with Vatican looking for ways of communication with catholic church and believers in the USSR under conditions of church and religion persecution and authority's strict control over moving home, correspondence and personal contacts between priests and congregation and different foreign organisations as well. To establish links, obtain information and provide financial and moral support Vatican used such ways as receiving information from priests moving temporarily into the country or leaving it, from cloisterers and laymen as well as involving foreign diplomats. The most vulnerable was official correspondence even if letters were delivered by embassies and consulates.
