This chapter sets out the latest scholarly thinking on the women’s movement during the interwar years and lays out the conceptual framework for the book, constructing a metaphor for the masculine public sphere and the struggles of the women who tried to access it. It suggests that women who wanted to leave the domestic sphere during this time needed to be possessed of a kind of disruptive energy to enable them to escape from the rigid destiny planned for them. It emphasises, particularly, the indivisibility of women’s activism during the interwar years from their writing, either in public journals or in private letters and diaries. This chapter also discusses the pros and cons of academic study using biography as a method.
