Chapter 5 turns to the economic sphere, with special attention to the emergence of the modern economic corporation, as a competitor par excellence. I examine its origins in medieval antecedents, how post-revolutionary US was the ideal environment for its initial cultivation and elaboration, and its subsequent development in Europe and beyond. The economic firm is in many ways the ‘ideal type’ of the modern corporate actor, but I am concerned to show in the next two chapters that new corporate actors in the political and ideological/cultural spheres are also crucial to the general domestication of competition in liberal societies.
