This paper looks at the evolution of the girl's school story in "The British Girl's Annual" during the interwar period. The school story played a crucial role instructing young female readers about their gendered role within the school as a kind of microcosm for nation/empire. Most of these lessons focus on loyalty and leadership, topics especially important during a period when British global leadership is in flux. For during this interwar period, many of the dominion--especially Canada--began to push back against the strictures of colonialism and demand political and economic autonomy, demands which eventually culminated in the 1931 Statute of Westminster. Distributed throughout the commonwealth, "The British Girl's Annual" (renamed "The Canadian Girl's Annual" or "The Australasian Girl's Annual" in its respective countries) tracks this shifting political climate in its representation of female leadership and defense of nation in the girl's school story. In particular, the annual's turn to the Guide story (as a subset of the school story), focusing on themes such as robbery and the defense of school-as-nation, charts a sociopolitical turn inward and the eventual collapse of both global empire and "The British Girl's Annual" itself during the final years of this interwar period.
