Histories of family secrecy are often emotionally, morally, and politically ambivalent. They entail fear, shame, pain, and repression, but they also often involve solicitude, tenderness, and degrees of tolerance. This special issue takes secrecy practices as a lens through which to examine the emotionally charged micropolitics of the family and its intertwinements with macropolitical currents, institutional practices, economic patterns, and wider social norms. The present introduction reflects on the key concepts of secrecy and family. In addition, it places the different contributions of the issue in a wider context by outlining some of the main questions and problems related to the historical study of family secrets in dialog with existing literature on the subject.
