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.
Cultural hegemony
In a society, cultural hegemony is neither monolithic intellectual praxis, nor a unified system of values, but a complex of stratified social structures, wherein each social and economic class has a social purpose and an internal class-logic that allows its members to behave in a way that is particular and different from the behaviours of the members of other social classes, whilst co-existing with them as constituents of the society.
