50 famous mysteries of the history of the XX century

The twentieth century has already become history, and it turned out that during this period there were no less mysterious events than in antiquity. Today we can not complain about the lack of information about certain events - we are supplied with scientific and popular publications, newspapers and magazines, and recently the Internet. But are we always satisfied with a simple knowledge of the facts? We are no less interested in the causes and consequences of what happened. We know that the assassination of the heir to the Austrian throne was the cause of the First World War, but who "ordered" Franz Ferdinand, who needed events to unfold in such a scenario? The question of whether Hitler really committed suicide is still relevant. There are many "dark places" in the history of the second half of the twentieth century: for example, the assassination of the 40th President of the United States John F. Kennedy, the so-called incident in Roswell (a UFO) or the death of the first astronaut Yuri Gagarin. We offer the reader to get acquainted with different versions of the most resonant events of the twentieth century.
