Imperial Bedlam is strategically written to analyze a cross-cultural debate over the conception of madness in colonial western Nigeria. Reviewing this piece after two decades not only provides a medium for renewing a discourse for recent and essential inquiry in Nigeria healthcare but also because the book remains relevant and significant to understanding the history of mental illness in Nigeria and the impact of colonialism on mental illness, which is a contemporary matter of concern in a world enamored by the consequence of poverty, compromised education, gender inequality, ill-health, violence, and other global challenges.
