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.
Hegemony
From the Gramsci analysis derived the political science denotation of hegemony as "leadership"; thus, the historical example of Prussia as the militarily and culturally predominant province of the German Empire (Second Reich 1871–1918); and the personal and intellectual predominance of Napoleon Bonaparte upon the French Consulate (1799–1804). Contemporarily, in "Hegemony and Socialist Strategy" (1985), Ernesto Laclau and Chantal Mouffe defined hegemony as a political relationship of power wherein a sub-ordinate society (collectivity) perform social tasks that are culturally unnatural and not beneficial to them, but that are in exclusive benefit to the imperial interests of the hegemon, the superior, ordinate power; hegemony is a military, political, and economic relationship that occurs as an articulation within political discourse. Beyer analysed the contemporary hegemony of the United States at the example of the Global War on Terrorism and presented the mechanisms and processes of American exercise of power in 'hegemonic governance'.
