Historical background

From the right-wing perspective, the social phenomenon of political totalitarianism is a product of Modernism, which the philosopher Karl Popper said originated from humanist philosophy; from the Republic (res publica) proposed by Plato in Ancient Greece, from Hegel 's conception of the State as a polity of peoples, and from the political economy of Karl Marx in the 19th century —yet historians and philosophers of those periods dispute the historiographic accuracy of Popper's 20th-century interpretation and delineation of the historical origins of totalitarianism, because the ancient Greek philosopher Plato did not invent the modern State.

In the early 20th century, Giovanni Gentile proposed Italian Fascism as a political ideology with a philosophy that is "totalitarian, and the Fascist State—a synthesis and a unity inclusive of all values—interprets, develops, and potentiates the whole life of a people". In 1920s Germany, during the Weimar Republic (1918–1933), the Nazi jurist Carl Schmitt integrated Gentile's Fascist philosophy of united national purpose to the supreme-leader ideology of the Führerprinzip. In the mid 20th-century, the German academics Theodor W. Adorno and Max Horkheimer traced the origin of totalitarianism to the Age of Reason (17th–18th centuries), especially to the anthropocentrist proposition that: "Man has become the master of the world, a master unbound by any links to Nature, society, and history", which excludes the intervention of supernatural beings to earthly politics of government.

In the essay "The 'Dark Forces', the Totalitarian Model, and Soviet History" (1987), by J.F. Hough, and in the book The Totalitarian Legacy of the Bolshevik Revolution (2019), by Alexander Riley, the historians said that the Russian Marxist revolutionary Lenin was the first politician to establish a sovereign state of the totalitarian model. As the Duce leading the Italian people to the future, Benito Mussolini said that his dictatorial régime of government made Fascist Italy (1922–1943) the representative Totalitarian State: "Everything in the State, nothing outside the State, nothing against the State." Likewise, in The Concept of the Political (1927), the Nazi jurist Schmitt used the term der Totalstaat (the Total State) to identify, describe, and establish the legitimacy of a German totalitarian state led by a supreme leader.

American historian William Rubinstein wrote that:

The 'Age of Totalitarianism' included nearly all the infamous examples of genocide in modern history, headed by the Jewish Holocaust, but also comprising the mass murders and purges of the Communist world, other mass killings carried out by Nazi Germany and its allies, and also the Armenian genocide of 1915. All these slaughters, it is argued here, had a common origin, the collapse of the elite structure and normal modes of government of much of central, eastern and southern Europe as a result of World War I, without which surely neither Communism nor Fascism would have existed except in the minds of unknown agitators and crackpots.

After the Second World War (1937–1945), U.S. political discourse (domestic and foreign) included the concepts (ideologic and political) and the terms totalitarian, totalitarianism, and totalitarian model. In the post-war U.S. of the 1950s, to politically discredit the anti-fascism of the Second World War as misguided foreign policy, McCarthyite politicians claimed that Left-wing totalitarianism was an existential threat to Western civilisation, and so facilitated the creation of the American national security state to execute the anti-communist Cold War (1945–1989) that was fought by client-state proxies of the US and the USSR.
