Menâpirzade Mustafa Nuri Bey (1844–1906) was an Ottoman bureaucrat, intellectual, and political activist, best known as the author of Mebahis-i İlm-i Servet (1882) or مباحث علم ثروت, among the earliest systematic works of political economy in the Ottoman Empire. Comprising two volumes and written in a dialogical style, the book is neither a mere translation of European treatises nor a derivative compilation. Rather, it synthesises Islamic intellectual traditions, Ottoman reformist debates, and modern European political economy into a distinctive framework. Though it did not circulate widely, its originality and scope render it a crucial source for understanding the evolution of Ottoman economic thought. Nuri Bey’s career, from Young Ottoman dissident to senior official under Abdülhamid II, mirrors the broader intellectual and political transformations of the nineteenth century. His conception of ilm-i servet (science of wealth) aimed to serve as a guidebook for reformist ambitions in the Ottoman state.
