Trade thrived during the Middle Ages. Konstanz owned the only bridge in the region, which crossed the Rhine, making it a strategic location in the [[Duchy of Swabia]]. Its [[linen]] production had made an international name for the city and it was prosperous. In 1192, Konstanz gained the status of [[Free Imperial City|Imperial City]] so it was henceforth subject only to the [[Holy Roman Emperor]].

[[Ulrich von Richental]]'s illustrated chronicle of the Council of Constance testifies to all the major happenings during the Council as well as showing the everyday life of medieval Konstanz. The ''Konzilgebäude'' where the conclave was held can still be seen standing by the harbour. Close by stands the ''[[Imperia (statue)|Imperia]]'', a statue that was erected in 1993 to commemorate the Council.
In 1460, the [[Old Swiss Confederacy|Swiss Confederacy]] conquered [[Thurgau]], Konstanz's natural [[hinterland]]. Konstanz then made an attempt to get admitted to the Swiss Confederacy, but the forest cantons voted against its entry, fearing over-bearing city states; Konstanz then joined the [[Swabian League]] instead. In the [[Swabian War]] of 1499, Konstanz lost its last privileges over Thurgau to the Confederation.
