Abstract: Borders and Freedom of Movement in the Holy Roman Empire tells the history of free movement in the Holy Roman Empire of the German Nation, one of the most fractured landscapes in human history. The boundaries that divided its hundreds of territories make the Old Reich a uniquely valuable site for studying the ordering of movement. The focus is on safe conduct, an institution that was common throughout the early modern world but became a key framework for negotiating free movement and its restriction in the Old Reich. The book shows that attempts to escort travellers, issue letters of passage, or to criminalize the use of ‘forbidden’ roads served to transform rights of passage into excludable and fiscally exploitable goods. Mobile populations—from emperors to peasants—defied attempts to govern their mobility with actions ranging from formal protest to bloodshed. Newly designed maps show that restrictions upon moving goods and people were rarely concentrated at borders before the mid-eighteenth century, but unevenly distributed along roads and rivers. In addition, the book unearths intense intellectual debates around the rulers’ right to interfere with freedom of movement. The Empire’s political order guaranteed extensive transit rights, but apologies of free movement and claims of protection could also mask aggressive attempts of territorial expansion. Drawing on sources discovered in more than twenty archives and covering the period between the late sixteenth to the early nineteenth century, the book offers a new perspective on the unstable relationship of political authority and human mobility in the heartlands of old-regime Europe.
