Carole Pateman’s idea of the "sexual contract" can be adapted to study the nationalist imagination. If a society defined through a sexual contract is equated to the "civic nation," then the sexual basis of an "ethnic nation" might be called the "gentleman’s agreement." The terms of the gentleman’s agreement, while never articulated as clearly as the sexual contract, nevertheless reveal themselves in cultural practices. Hungarians presupposed a nation consisting of ennobled men capable of seducing women to the "national brotherhood." Hungarian ideas about the nation evolved during the nineteenth century, and Hungarian ideals of masculinity also changed: a manliness of strength increasingly gave way to a masculinity of education or refinement. Although the different types of masculinity implied different attitudes toward women, they both rested on similar cultural assumptions. This article links the cultural history of Hungarian national masculinity to everyday practices, notably moustaches, cigars, and sexuality.
