The voyages of exploration and expansion that were launched from Spain and Portugal in the early modern era, brought with them a militant Roman Catholicism, which sought to convert indigenous peoples to the Latin Church. What the Iberians discovered in the Americas, Africa and Asia were multiple, complex polities with their own religious traditions, which strongly resisted conversion. This conference will examine Ibero-Indigenous religious contact through the lens of indigenous peoples' responses to Spanish and Portuguese religious imperialism. Taking examples from Mexico, South America, Africa and Asia we hope to find some common links in seeing how religious resistance to the Iberians manifested itself in the sixteenth, seventeenth and eighteenth centuries.
