Counter-Hegemony in the Theory of the Multipolar World
The classical realists use the term “hegemony” in a relative sense and understand it as the “actual and substantial superiority of the potential power of any state over the potential of another one, often neighboring countries.” Hegemony might be understood as a regional phenomenon, as the determination of whether one or another political entity is considered a “hegemon” depends on scale. Thucydides introduced the term itself when he spoke of Athens and Sparta as the hegemons of the Peloponnesian War, and classical realism employs this term in the same way to this day. Such an understanding of hegemony can be described as “strategic” or “relative.”
In neo-realism, “hegemony” is understood in a global (structural) context. The main difference from classical realism lies in that “hegemony” cannot be regarded as a regional phenomenon. It is always a global one. The neorealism of K. Waltz, for example, insists that the balance of two hegemons (in a bipolar world) is the optimal structure of power balance on a world scale. R. Gilpin believes that hegemony can be combined only with unipolarity, i.e., it is possible for only a single hegemon to exist, this function today being played by the USA.
