Magnum Crimen
The book describes activities of the Roman Catholic clergy in the Kingdom of Yugoslavia, including their intention and attempts to become above the state, to control the state and eventually everyday lives of the common people. It has two  distinct parts. The first part consists of fifteen chapters, covering the Roman Catholic clericalism from the end of the nineteenth and beginning of the twentieth century in Austria-Hungary, then in the Kingdom of Yugoslavia.  The second part, the last four chapters, covers the rise and fall of the Independent State of Croatia, and the active support of the Roman Catholic Church clergy.
