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
Culturally, hegemony also is established by means of language, specifically the imposed "lingua franca" of the hegemon (leader state), which then is the official source of information for the people of the society of the sub-ordinate state. Writing on language and power, Andrea Mayr says, "As a practice of power, hegemony operates largely through language." In contemporary society, an example of the use of language in this way is in the way Western countries set up educational systems in African countries mediated by Western languages.
