The book deals with complex and eventful lives and political works of the Yugoslav political emigrants in Prague. Approximately 150 Yugoslav communists (including Anton Rupnik, Josip Milunić, Teodor Balk) trained themselves for overtaking the power in their homeland.
Consequently, from the second half of the 1950s, the emigrants solved a dilemma whether they should return home or stay abroad permanently. In the former case the question of forms of further political activity was raised.
The author clarifies one segment of the field of research that has not been explored in detail until now, namely the Czechoslovak communist party's aid of foreign communists. Proceeding from a detailed analysis of Czechoslovak as well as Yugoslav archival sources the author explains not only the activity of emigrants, but also other aspects of their life in the communist Czechoslovakia.
Further, he shows how this almost unknown "immigrant wave" entered the Czechoslovak and Czech public life.
