The concept of a “great German peace” became a guiding star for many generations of Germans. It was a source of inspiration for brilliant poets and composers and building material for the rise of thousands of politicians: from Bismarck's Pan-Germanists to Hitler's fascists. But what price did ordinary Germans pay for this? The author briefly and fascinatingly tells the history of Germany and shows with examples how the leaders of one of the most successful and developed countries in the world led it to collapse. They acted with the best and rational intentions and wanted the well-being and prosperity of the German people. It seemed that they had discovered the most powerful source of energy for progress - the national idea, free from the original sins of globalism and internationalism. Those. from the greed of capitalists and the fantasies of communists. The result: two world wars, tens of millions of killed and tortured people and the complete destruction of the concept of Greater Germany. The book in many ways answers the questions in a new way: – What were the causes of the First and Second World Wars? – What led to the growth of nationalism in Europe in the 19th century – the beginning of the 20th century? – Where is the fine line between nationalism and Nazism?
