Revisionist historians have convincingly argued that Spanish American independence was not the result of simmering grievances that galvanised a national or Creole identity against Spain. Instead, this scholarship insists that Spanish American national identities did not exist at the time and that independence was an unforeseen process that must be understood in the context of the Napoleonic invasion of Iberia. But, if independence was undesirable before 1808 and if national identities arose at a latter period, how do we explain the early independence projects of ‘precursors’ like Juan Pablo Viscardo y Guzmán? By contextually reconstructing the logic behind Viscardo's projects, this article offers a new perspective on the intellectual conditions of possibility for Spanish American independence. It argues that though he certainly identified as a Creole from Peru, Viscardo actually deployed an Enlightenment global science of commerce, not Creole patriotism or nationalism, to legitimate Spanish American independence.
