At the beginning of the communist era, in time of general rejoicing for the unity with the Slavic Soviet Union, the author described the historical roots of Pan-Slavism - from German Romanticism through the Czech Revival up to Pan-Russism - and its use by Soviet as well as Czechoslovakian Communists.

Černý’s work was a documentary about the hidden resistance of the Czech spirit - however, the book is absolutely topical today: The massively increasing Russian presence in the Czech Republic at the beginning of the 21st century requires an understanding of why so many Russians may sincerely believe that the Czech lands are part of their sphere - and why the talk of some Czech politicians about friendship with Russia is so dangerous for the Czech national interests.

The Development and Crimes of Pan-Slavism should become a required reading for every Czech teacher and journalist.
