Book excerpt: Historiographically this book rests on the fact that European transitions to modern economic growth were obstructed and promoted by the Revolution in France and 15 years of geopolitical conflict sustained by Napoleon in order to establish French Hegemony over the states and economies of Britain, France, Germany, the Netherlands, Italy, Spain, Portugal and overseas commerce. The chapters reveal that their authors concerns to analyse both the nature and significance of connections between geopolitical and economic forces lend coherence to a collaborative endeavour utilising comparative methods to address a mega question. What might be plausibly concluded about the economic costs and the benefits of this protracted conjuncture of Revolutionary and Napoleonic Warfare? Contributors are: Patrick Karl O’Brien, Loïc Charles, Guillaume Daudin, Silvia Marzagalli, Marjolein ’t Hart, Johan Joor, Mark Dincecco, Giovanni Federico, Leandro Prados de la Escosura, Carlos Santiago-Caballero, Cristina Moreira, Jaime Reis, Rita Martins de Sousa, and Peter M.Solar.
