Even though there is a tons of literature written about the events of the First and Second World Wars, the historians still voice their debates that the true history of the 20th century hasn’t been written yet. Indeed, there are still no meaningful answers to the questions: who unleashed the First World War, why did the October Revolution in Russia happen, what were the true reasons for the Second World War? For these and other questions, the author is trying to find the answers in his book. Of course, there is absolutely no way to justify the horrors of the war, but a different perspective of the generally held opinions of the historical events allows one to look at this troubling period in European and World history differently and make critical conclusions for the present. The book is appropriate for a wide audience.
