In the field of cultural studies, posthegemony has been developed as a concept by a number of critics whose work engages with and critiques the use of cultural hegemony theory within the writings of Ernesto Laclau and within subaltern studies. George Yúdice, in 1995, was one of the first commentators to summarize the background to the emergence of this concept:
Flexible accumulation, consumer culture, and the "new world information order" are produced or distributed globally, to occupy the space of the nation, but are no longer "motivated" by any essential connections to a state, as embodied, for example, in a "national-popular" formation. Their motivations are both infra- and supranational. We might say that, from the purview of the national proscenium, a posthegemonic situation holds. That is, the "compromise solution" that culture provided for Gramsci is not now one that pertains to the national level but to the local and transnational. Instead, the "culture-ideology of consumerism" serves to naturalize global capitalism everywhere .
The concept of posthegemony is related to the rise of the "multitude" as a social force which, unlike the "people", cannot be captured by hegemony, together with the roles of affect and habitus in mechanisms of social control and agency. Posthegemony and its related terms are influenced by Gilles Deleuze and Félix Guattari, Pierre Bourdieu and Michael Hardt and Antonio Negri’s accounts of the supra- and infra-national forces that are said to have rendered obsolete the national-popular forms of coercion and consent through which, for Antonio Gramsci, hegemony structured and constituted society. The features of posthegemony as a concept correspond closely to those of postmodernity. Thus, posthegemony theory argues that ideology is no longer a political driving force in mechanisms of social control and that the modernist theory of hegemony, which depends on ideology, therefore no longer accurately reflects the social order. Some commentators also argue that history is not, as Karl Marx described it, a class struggle, but rather a "struggle to produce class". The concept of posthegemony also resonates with the work of post-Foucauldian theorists such as Giorgio Agamben. Nicholas Thoburn, drawing on Agamben's discussion on the "state of exception", writes that "it is, perhaps, with the recasting of the relationship between law and politico-military and economic crises and interventions that is instituted in the state of exception that the time of hegemony is most revealed to have passed."
In international relations
In international relations, posthegemony refers to the decline of the US unilateral hegemony. This has likely been the result of the difficulties that have arisen out of the unilateral style foreign policy. These difficulties predominantly include disdain from; those directly affected by the, sometimes forceful, hegemonic actions of the US, those who spectated the actions, and even Americans themselves who view the actions of their government as immoral. For example, after the Vietnam War, in 1978, 72 per cent of Americans thought the war was not a mistake but fundamentally wrong and immoral. This exemplifies the hegemonic decline: how could the US maintain the legitimacy of their interventions if their own citizens find them wrong and immoral? The dominant power of the world is/are fluid, the initial period of US unilateralism can be loosely pinpointed to their interventions during the world wars. Following this period of rising US dominance on the world stage, The predictions of these individuals represent the fluidity of power over time, through the idea that, during the period where the US was unequivocally dominant, people could still see the inevitable future, of a change in power and authority, on the world stage.
Criticism
Among the criticisms of the theory of posthegemony is Richard Johnson's, that it involves "a marked reduction of social complexity." Johnson concedes that "one considerable achievement of 'the post-hegemony project' is to draw many observable post-9/11 features into a single imaginative picture, while also synthesizing different currents in contemporary social theory." But he argues that "it is strange, however, that the result is viewed as the end of hegemony rather than as a new hegemonic moment." He, therefore, calls for a rejuvenation of the concept of hegemony, rather than its abandonment.
