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 and Socialist Strategy
Hegemony and Socialist Strategy is a 1985 work of political theory in the post-Marxist tradition by Ernesto Laclau and Chantal Mouffe. Developing several sharp divergences from the tenets of canonical Marxist thought, the authors begin by tracing historically varied discursive constitutions of class, political identity, and social self-understanding, and then tie these to the contemporary importance of hegemony as a destabilized analytic which avoids the traps of various procedures Mouffe and Laclau feel constitute a foundational flaw in Marxist thought: essentializations of class identity, the use of "a priori" interpretative paradigms with respect to history and contextualization, the privileging of the base/superstructure binary above other explicative models.
