Swedish–Brandenburg War

The Swedish-Brandenburg War was an independent conflict between Brandenburg-Prussia, Denmark, and Sweden from 1674 and 1679, fought in the context of the Franco-Dutch War. Sweden was an ally of France, while Denmark and Brandenburg-Prussia were allied with the Netherlands and Austria. In the first part of the war the Brandenburgers fought off an invasion by the Swedes of the March of Brandenburg and then, with the Danes and their other allies, conquered the Swedish possessions in Germany, Swedish Pomerania and Bremen-Verden, in a slow campaign lasting until 1678. After 1676, Denmark was involved in the Scanian War on the southern tip of the Scandinavian Peninsula and in the Baltic Sea, which though often referred to as a separate and distinct conflict, was deeply intertwined with the fighting in Germany and the Danish alliance with Brandenburg-Prussia. A Swedish invasion of East Prussia undertaken in late 1678, was successfully beaten back by the Brandenburger prince-electors.

The war between Brandenburg and Sweden ended on June 29, 1679 with the Treaty of Saint-Germain-en-Laye. On September 26, 1679, Denmark and Sweden concluded the Treaty of Lund Scanian War. Despite Brandenburg-Prussia's victories on the battlefield, due to the constellation of powers in Europe, it was awarded only a small fraction of the territory it had conquered. Between Sweden and Denmark the pre-war borders were re-established.
