The evolution of the Swiss Confederation from a local alliance among Imperial estates to a national entity on the European stage can be mapped by tracking the way that federal business was archived from the fifteenth to nineteenth centuries. The original Diet (Tagsatzung) established after the allied cantons gained shared territories in the Aargau in the 1420s lacked the personnel or institutional identity necessary to undertake any archival activity. As the Confederation gained institutional definition and became a regional player in the politics of the Holy Roman Empire and of Central Europe, however, documentary practices became increasingly routinized, and stable federal collections began forming in parallel in the archives of the leading cantons. Consisting of durable representations of ongoing debates and negotiations and preserved in documents (Abschiede) that were circulated differentially depending on the matters and parties involved, the emerging confederal archive was distributed in that no single location possessed a complete version, and imaginary in that contemporaries regarded it as a comprehensive unity despite its very real physical and material fragmentation. In the later sixteenth century, a separate archival collection reflecting the Confederation’s shared business emerged in the administrative centre of Baden (Aargau), reflecting the consolidating identity of Confederation as it moved out of the Empire’s orbit. Repeated efforts in the seventeenth and eighteenth centuries to complete and protect this collection referred to it as an archive despite its unusual characteristics. In the late eighteenth and nineteenth century, projects to create a Swiss national archive, either virtually or in print, culminated in the printed Eidgenössische Abschiede that created a documentary record of a Swiss state since the thirteenth century that had never existed historically.
