Hegemony
In the 19th century, hegemony came to denote the "Social or cultural predominance or ascendancy; predominance by one group within a society or milieu". Later, it could be used to mean "a group or regime which exerts undue influence within a society". Also, it could be used for the geopolitical and the cultural predominance of one country over others, from which was derived "hegemonism", as in the idea that the Great Powers meant to establish European hegemony over Asia and Africa.
International regime
Some scholars emphasize the importance of a hegemon in creating a regime and giving it momentum. This is called the hegemonic stability theory. The United States, for example, has been instrumental in creating the Bretton Woods system, with organizations such as the World Bank and the International Monetary Fund. The rationale is that a hegemon, being the dominant actor in international politics and economics, often stands to gain the most from the creation of global standards. For instance, while other countries might benefit from it, U.S. companies like Microsoft, Universal Studios, and Pfizer would be among the greatest beneficiaries of a strict global intellectual property regime. As the hegemons use their power to create regimes, their withdrawal similarly can also threaten the effectiveness of regimes.
