## History

Kaiserstuhl is first mentioned around 1227–34 as domino Arnoldo de Keiserstul. In 1236 it was mentioned as de Kayserstule. The name and coat of arms come from the Freiherr of Kaiserstuhl, whose castle guarded the right bank of the Rhine. In 1359, the name of the castle changed to Rotwasserstelz Castle. The sale of remote properties lying on both sides of the Rhine to Wettingen Abbey by Rudolf of Kaiserstuhl and his wife Adelheid von Tengen in 1254/55 enabled the expansion of the settlement on left bank of the Rhine. The wall and upper tower (raised to today's height after a fire in 1360) are dated archaeologically to 1260. Construction of the new town also involved the noble Lütold VII von Regensberg, whose descendant, Lütold IX, in mentioned in 1279 as the owner of the city. In 1294 his son sold it with the bridge, castle and other rights in the surrounding villages to Bishop Henry II of Constance. It remained part of the Bishop's holdings until 1798. The Bishop's reeve at Rötelen Castle managed the city and held the low court rights. The independent area of law covered only the area within the city walls, and before the upper gate as well the banks of the Rhine. The left bank territory included fields and gardens, while the area on the right was five times larger and held vineyards and fields for the citizens of the town. The citizenry rights and obligations was first defined in 1310. After 1287, they choose mayors, an eight-member Council and the Court from their midst, which was equal with the episcopal steward, who was almost always an outsider. Further attempts to expand the legal power of the local leaders were rejected in the treaties of 1526, 1535, 1578 and 1687.
In 1365–66 and 1384–85 the town served as a refuge for the Bishop of Constance when he was expelled from the Constance. Before 1324 and between 1371 and 1386 the city was pawned to outside owners as collateral for a loan. From 1359 to 1403 the castle was owned by the locals. In 1374 they were granted an exemption of the war tax. The episcopal rule was weakened by the transition of sovereignty from the Habsburg to the County of Baden in 1415. Due to its location on the religious boundary Kaiserstuhl presented an important bridgehead for the Catholic regions. In both the First War of Villmergen, in 1655/56, and the Toggenburg War (or Second War of Villmergen), in 1712, the village was occupied by Zurich. During the religious conflicts, traffic to Kaiserstuhl was forced to instead cross the Rhine in Zurich controlled areas. As the town did not have the right to tax ship traffic on the Rhine, this loss of land traffic cost the town most of its custom revenue. However, the town remained prosperous due to viticulture and animal husbandry, through the credit and banking, and through foreign service. The prosperity is reflected in the stately houses built during this era. (Gasthaus zur Krone in 1550, administration hall of the monastery of St. Blaise in 1563 and 1612, and the Marschallhaus in 1764). The buildings that allowed Kaiserstuhl to function as a regional center were on the right bank of the Rhine, and were lost in 1798 with the creation of the Canton of Baden. After the destruction of the bridge by the French in 1799 border traffic through Kaiserstuhl ended for almost two decades.
Floods damaged the Rhine Bridge in 1817 and 1876. It was rebuilt in steel and concrete in 1890 and again in 1985. The creation of the post offices in 1816 and the pony express line to Baden, led to prosperity and growth. This culminated in the establishment of the district school in 1836 and a Savings Bank (1837–1916). However, after 1850 the prosperity and growth ended. In 1861 ten houses along Rheingasse were destroyed in a fire, but were never rebuilt. The railway station was opened in 1876 on the railway line Koblenz-Winterthur. The old station was replaced in 1995. Between 1870 and 1911 modern technological infrastructure, including telegraph, telephone and electricity from the power plant Beznau, entered the town. But even with the increased infrastructure, industry hardly settled in Kaiserstuhl. The only industry was textiles, such as an embroidery plant that in 1913 had 33 employees.
