Early capitalism enclosed bourgeoisies within rival national economies rather than a world system.

Evidence

The class that is so consistently identified with the appearance of industrial capitalism was inextricably associated with specific “rational” structures—a relationship that profoundly influenced bourgeois imaginations and realizations. Political economies, that is national economies, enclosed them, and thus the bourgeoisie perceived what later analysis argues in retrospect is the beginnings of a world system as something quite different: an international system. The bourgeoisies of early modern capitalism were attempting to destroy or dominate each other. — Cedric J. Robinson, Black Marxism_ The Making of the Black…, 184
