The emergence of two powerful totalitarian ideologies - communism and fascism - was the most ambitious event in the history of human civilization. Majestic empires and tens of millions of dead, industrial breakthroughs and bloody wars, the revival of national cultures and cruel terror - all this is connected in our minds with two concepts: fascism and communism. However, how legitimate is the comparison of these phenomena? And what is communism anyway? After all, there was Soviet “real socialism”, there was Maoism, Trotskyism, Guevaris - and all of them not only did not get along with each other, but also waged a merciless struggle for mutual destruction. The same applies to fascism: there was its Italian version, but there was also German Nazism , and Spanish Falangism, and clerical fascism, and authoritarian regimes in the Baltic countries, and military juntas in Latin America - they are countless. And they were all different from each other, they were at enmity with each other, they competed and rarely collaborated. Finally, there were hybrid movements between fascism and communism: national revolutionism, national bolshevism. And not only were they, but they are! In this collection, for the first time, an attempt has been made to understand this enchanted tangle of totalitarian ideologies.
