Constructing Imperial Spaces: Habsburg Cartography in the Age of Enlightenment Summary and Table of Contents In the second half of the eighteenth century, military engineers working for the Austrian Habsburg monarchs mapped in detail for the first time the provinces and borders of their empire. Despite this development, there is a disjunction in the literature between scholars who examine the Habsburg monarchy’s evolution under Maria Theresa (1740–1780) and Joseph II (1765–1790), and those who investigate maps and mapping in the period. This historiographical divide prevents scholars from considering the part maps may have played in the efforts of the Habsburg monarchs to construct a centralized “territorial nation” as a serious contender to nation-states premised on ethnic homogeneity. Maria Theresa’s and Joseph II’s military, social, religious and economic reforms, and their attempts to increase uniformity within their dominions – which intensified practices, such as mapping and the making of geographic descriptions, and surveys of demographic and natural resources – suggest a modernising entity whose rulers sought to adapt it to the contemporary world. My thesis analyses the production, circulation, and use of large-scale topographic provincial and border Habsburg maps for three provinces: the Austrian Netherlands, Lombardy, and Transylvania. Based on archival sources located in Vienna, Brussels, ClujNapoca, Milan, Paris and Sibiu, I show how Maria Theresa’s and Joseph II’s desire to map their dominions led to the establishment of imperial corps of military engineers and the development of a network of scientific centers promoting the study of astronomy and geography. Once they had established a number of mapmaking institutions and recruited or educated a new generation of military engineers, the Habsburg rulers commissioned the first detailed topographic survey of their lands and prepared cartographic material to be used in border regulations with their neighbors. Maps offer a new angle to interpret and assess the efficiency of early modern governments to construct centralized empires, such as the Habsburg monarchy. Maria Theresa’s and Joseph II’s determination to obtain a detailed image of their domains and imperial borders illustrates the reliance of Enlightenment rulers on emergent sciences, such as cartography, to further the defence and expansion of their empires. The first chapter functioning as an introduction, “Habsburg Cartography in the Age of Enlightenment,” situates the development of Habsburg cartography in the global context of eighteenth-century imperial mapmaking enterprises. Moreover, I discuss the impact of the Habsburg fiscal-military state on mapmaking practices within the Monarchy. Influenced by cameralist economic theories and political practices that scholars call Enlightened Absolutism, Maria Theresa (1740-1780), Joseph II (1780-1792) and Chancellor Kaunitz (1753-1793) relied on cartography as a preliminary step in preparing the defense and reform of the empire.
