F this introduction to a special issue of Central European History (CEH) or any other collection of articles on Third Reich masculinity had been published twenty or twentyfive years ago, it would have begun by bemoaning the neglect of men and masculinity in gender history. Such an article would have lamented the fact that the dominant stream of gender studies proceeds "as if gender applied only to women," as the sociologist Michael Kimmel, one of the pioneers of the established field of Men's Studies, still put it in 2004 in his popular reader The Gendered Society. 1 Since the 1990s, however, sociologists, anthropologists, literary scholars, theologians, psychologists, and many others, not least historians, have filled bookshelves with inquiries into men's acting, thinking, and feeling in gendered ways. 2 These scholars have made men visible as gendered subjects and perforated the veil of unmarked normative masculinity. They have shown that norms, ideas, and practices addressed as masculine, manly, or unmanly, or as feminine or womanly, are not emanations from biological givens, but that they are socially and culturally constructed, that they change over time, and that they vary from one society to another, as well as within societies, cultures, and even individuals. Their work has contributed to a comprehensive understanding of gender as a marker of biological sex and of social practices, imageries, and ideologies that organize power relations, hierarchies, and identities between and within the sexes, often by exploring intersections with other categories of social difference, such as race, class, and age. 3 I would like to express my deep gratitude to Andrew I. Port for his superior guidance in putting together this special issue and for his superb editing of my and all the other articles.
