Obersee (Lake Constance)

The naval war on Lake Constance (German: Seekrieg auf dem Bodensee) was a series of conflicts that took place on Lake Constance, beginning in 1632, in the context of the Thirty Years' War (1618 to 1648). At that time various powers ruled different parts of the shoreline: in the north and east was Roman Catholic, Habsburg Anterior Austria; in the northwest and west the troops of the Protestant Duchy of Württemberg with their allies from Kingdom of Sweden and Kingdom of France. These various powers sought, for strategic reasons, to exercise their hegemony over the area of Lake Constance. Only the partly Catholic and partly Protestant southern shore which belonged to the Old Swiss Confederacy maintained an uneasy neutrality due to their divided loyalties. The changing course of this post-war period of the Thirty Years' War brought no clear success to either party. The Protestant side (reinforced by France) could not seriously threaten imperial possessions; the Imperialists succeeded in maintaining their positions on the whole and to inflict telling losses on their enemy. Swedish/Württemberg naval domination in the last two years of the war had no wide-reaching significance by that stage.

The Battle of Lake Constance (Latin: Lacus Brigantinus) was a small naval battle between Roman forces and Celtic tribes in the spring of 15 BC.

Lake Constance (German: Bodensee, pronounced [ˈboːdn̩ˌzeː] (listen)) refers to three bodies of water on the Rhine at the northern foot of the Alps: Upper Lake Constance (Obersee), Lower Lake Constance (Untersee), and a connecting stretch of the Rhine, called the Lake Rhine (Seerhein). These waterbodies lie within the Lake Constance Basin (Bodenseebecken) in the Alpine Foreland through which the Rhine flows.The lake is situated where Germany, Switzerland, and Austria meet. Its shorelines lie in the German states of Baden-Württemberg and Bavaria, the Swiss cantons of St. Gallen, Thurgau, and Schaffhausen, and the Austrian state of Vorarlberg. The actual location of the border is disputed. The Alpine Rhine forms in its original course the Austro-Swiss border and flows into the lake from the south. The High Rhine flows westbound out of the lake and forms (with the exception of the Canton of Schaffhausen) the German-Swiss border as far as to the city of Basel.The most populous towns on the Upper Lake are Constance (German: Konstanz), Friedrichshafen, Bregenz, Lindau (Bodensee), Überlingen and Kreuzlingen. The largest town on the Lower Lake is Radolfzell am Bodensee. The largest islands are Reichenau in the Lower Lake, and Lindau and Mainau in the Upper Lake. While in English and the Romance languages, the lake is named after the city of Constance, the German name derives from the village of Bodman (municipality of Bodman-Ludwigshafen), in the northwesternmost corner of the lake.
