The work examines little-known pages in the history of the two world wars of the twentieth century associated with the countries of Latin America. The author explores what the First and Second World Wars brought to the peoples of Latin America, how the attitude of different layers of Latin American society to the events taking place on the battlefields, to the states participating in the two wars and to the wars themselves changed. An important place is given to the penetration of the Germans into South America, the use of the states of this continent by German agents during the Second World War, as well as the escape of the Nazis from punishment after the defeat of Germany to the countries of Latin America. Manifestations of fascism in Latin American states are explored. For historians, political scientists, sociologists, students and a wide range of people interested in the history of world wars and Latin American countries.
