The chapter introduces intersectionality and argues for its potential for the studies of men and masculinities. The first part of the chapter presents the history, reception, and implications of intersectionality. The second part puts forward seven basic principles and challenges of intersectional research. In order to illustrate some of the principles and challenges in relation to masculinity studies, the final part of the chapter outlines two examples of intersectional analysis. The first concerns public discourses about ethnic/racial minority young men; and the second concerns masculinity, war, and political radicalization. Finally, the article concludes by summing up how men and masculinity studies could benefit from a stronger focus on intersectionality.
