Privilege has long been understood as the constitutional basis of Ancien Re?gime France, legalising the provision of a variety of rights, powers and exemptions to some, whilst denying them to others. In this fascinating new study however, Jeff Horn reveals that Bourbon officials utilized privilege as an instrument of economic development, freeing some sectors of the economy from pre-existing privileges and regulations, while protecting others. He explores both government policies and the innovations of entrepreneurs, workers, inventors and customers to uncover the lived experience of economic development from the Fronde to the Restoration. He shows how, influenced by Enlightenment thought, the regime increasingly resorted to concepts of liberty to defend privilege as a policy tool. The book offers important new insights into debates about the impact of privilege on early industrialisation, comparative economic development and the outbreak of the French Revolution.
