Friedmann and McMichael's work, through their concept of the 'food regime', has been foundational to our thinking about the relation between capitalism, the state, and agriculture. Given the thirtieth anniversary of the publication of their seminal 1989 paper in this journal (Agriculture and the State System: The Rise and Decline of National Agricultures, 1870 to the Present) it seems very appropriate to commemorate this event by undertaking a reassessment of that paper. This article undertakes such a reassessment by examining and critiquing: the theoretical assumptions underlying the paper, particularly in relation to capitalism, class, and the state. This directs attention particularly to: the authors' (implicit) definition of capitalism; the relation between capitalism and the modern state; their treatment of 'class' and 'class struggle'; and their periodisation of food regimes and the dynamics underlying them, these being premised on their theoretical assumptions. The second, third, and, fourth sections occupy the bulk of the paper. The second section develops a significantly revised theoretical foundation for thinking about the dynamics underlying food regimes, while the third section deploys this as the basis for a new periodisation of food regimes. This periodisation includes a proposed Fifth, or 'Post-Neoliberal' Food Regime, and the final section examines this in detail.determinism and linearity of 'structural Marxism' (the 'second school', see below), an impulse, as implied above, that has only increased, if not always been realised, since 1989 (see Campbell and Dixon 2009). Indeed, these authors suggest that 'it is only possible… to understand the significance of these new perspectives by understanding food regimes as a key historical and theoretical pivot that moved debates in rural sociology from a rather narrow, structural and orthodox political economy of agriculture to a more contingent, historically contextual understanding of the many configurations… of agri-food capitalisms' (Campbell and Dixon 2009, p. 261).We argue, however, and as implied above, that, in the case of McMichael, theoretical provision for such 'contingency' has not been realised other than 'outside' the regime (see Tilzey 2017), while, in the case of Friedmann, her theoretical shift to engage 'contingency' has been undertaken through her partial embrace of post-structural and post-modern frames. These do not, we suggest, afford a rigorous basis for conceptualising 'contingency', however. We argue that this unresolved tension between 'structure' and 'contingency' in FRT, as presented by Friedmann and McMichael, arises through a missed opportunity to embrace RT in its entirety, together with their apparent lack of awareness of other important and related developments in 'post-structuralist' (but not 'post-structural') Marxian theorynotably, 'Political Marxism', Poulantzian state-capital theory, and neo-Gramscian theory. Indeed, it may be argued that this unresolved tension and their omission to present a theoretical basis for con...
