Switzerland’s history is one of a medieval defensive league formed during a time and in an area lacking imperial authority. The different cantons (traditionally called Orte in German) were to a large extent independent states that remained united through the shared defense of liberty, which was understood as the protection of imperial privileges and franchises. Unlike all similar confederations (e.g., the Hanseatic and Swabian leagues) and despite endemic internal strife, especially after the Reformation in the 16th century, the Swiss Confederation survived the formation of (princely) modern states without adapting to it. With Venice, Genoa, and the Netherlands, the confederation formed the republican exception in Europe, and it developed political structures less as a unified nation than on the level of the 13 cantons that the Swiss Confederation comprised by the time of the Reformation. The early modern confederation also included, with reduced say, the Zugewandte Orte, districts and towns (such as Geneva and Graubünden) that were allied to and subsequently became a party of the confederation.
