"Imperial Hygiene" by Alison Bashford offers a comprehensive cultural analysis of the connections between borders, hygiene, and race in the context of British colonialism and white Australian society. The book examines how public health functioned as biopolitical governance between 1850 and 1950, creating new power structures and social boundaries. By exploring topics such as vaccinations, quarantine, and the treatment of immigrants, it becomes clear how hygiene practices and racist ideologies are intertwined. Bashford highlights the role of hygiene in the creation and maintenance of colonial rule, illustrating how these practices contributed to the definition of national identities and the regulation of bodies and communities. The analysis ranges from the challenges of smallpox quarantine to the social implications of sexual hygiene and imperial control.
