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.
Hegemonic masculinity
As a sociological concept, the nature of hegemonic masculinity derives from the theory of cultural hegemony, by Marxist theorist Antonio Gramsci, which analyses the power relations among the social classes of a society. Hence, in the term "hegemonic masculinity", the adjective "hegemonic" refers to the cultural dynamics by means of which a social group claims, and sustains, a leading and dominant position in a social hierarchy; nonetheless, hegemonic masculinity embodies a form of social organization that has been sociologically challenged and changed.
