Ethnohistorians and other scholars have long noted how European colonial texts often concealed the presence and participation of indigenous peoples in New World conquests. This scholarship has examined how European sources (both texts and maps) have denied indigenous history, omitted indigenous presence, elided indigenous agency, and ignored indigenous spaces all while exaggerating their own power and importance. These works provide examples of colonial authors performing these erasures, often as a means to dispossess. What they lack, however, is a systematic means of identifying, locating, and measuring these silences in space and time. This article proposes a spatial history methodology which can make visible, as well as measurable and quantifiable the ways in which indigenous people and spaces have been erased by colonial narratives. It presents two methods for doing this. First, narrative analysis and geovisualization are used to deconstruct the imperial histories found in colonial European sources. Second it combines text with maps to tell a new (spatial) narrative of conquest. This new narrative reconstructs indigenous activity through a variety of digital maps, including ‘mood maps’, indigenous activity maps, and maps of indigenous aid. The resulting spatial narrative shows the Spanish conquest of Peru was never inevitable and was dependent on the constant aid of immense numbers of indigenous people.
