At present the first traceable use of the term psychopolitics is by the German jurist expert in international law Heinrich Rogge in Psychopolitics and the problem of the leader (Psychopolitik und Führerproblem, 1925).
Rogge’s prominence is also testified by the reviews that at least from 1934 to 1937 his writings on Hitler and on the prospect of peace in Europe obtained in the magazine Foreign Affairs, of the US Council on Foreign Relations (CFR).
