2. 1452–1456Reutlingen · SwabiaLeague cities formed joint militias, patrolled trade routes and the countryside together, and launched counterattacks against aggressive princes when necessary. Cities also reduced trade costs through unified tariffs and mutual judicial assistance, strengthening their control over surrounding rural markets.
3. 1456–1460Ulm · SwabiaThe Swabian urban leagues spoke with one voice in the Imperial Diet, seeking the emperor's recognition of urban autonomy. The tradition of urban alliances in the 1450s laid the foundation for the later, broader Swabian League and imperial city diplomacy.
