The term Oligarchical Collectivism refers to Ingsoc (English Socialism), the dominant ideology of Oceania, and to the ideologies of Neo-Bolshevism in Eurasia and Death Worship (Obliteration of the Self) in Eastasia. Winston reads two long excerpts establishing how the three totalitarian super-states – Eastasia, Eurasia, Oceania – emerged from a global war, thus connecting the past to his present, the year 1984, and explains the basic political philosophy of the totalitarianism that derived from the authoritarian political tendencies manifested in the twentieth century. That the three, ostensibly opposing ideologies are functionally identical is the central revelation of The Book.[6] Theoretically, Oligarchical Collectivism recalls the theory of bureaucratic collectivism put forth by some Trotskyists in the late 1930s as a description of the Soviet Union under Stalin. Oceania's principal enemy of the people, Emmanuel Goldstein, is modelled after Leon Trotsky, a former member of the inner circle of the Bolshevik Party whom Stalin purged and then declared an enemy of the people of the Soviet Union, the socialist state that Trotsky had helped found in Russia.[7] From exile, Trotsky criticised the social system of the Soviet Union. The Book has been described as a parody of The Revolution Betrayed: What is the Soviet Union and Where is it Going? (1937), by Leon Trotsky;[8] and The Managerial Revolution (1941), by James Burnham, a former Trotskyite.[9]
