The Scanian War was a part of the Northern Wars involving the union of Denmark–Norway, Brandenburg and Sweden. It was fought from 1675 to 1679 mainly on Scanian soil, in the former Danish and Norway provinces along the border with Sweden, and in Northern Germany. While the latter battles are regarded as a theater of the Scanian war in English, Danish, Norwegian and Swedish historiography, they are seen as a separate war in German historiography, called the Swedish-Brandenburgian War.
The war was prompted by Swedish involvement in the Franco-Dutch War. Sweden had allied with France against several European countries. The United Provinces, under attack by France, sought support from Denmark–Norway. After some hesitation, King Christian V started the invasion of Skåneland in 1675, while the Swedish were occupied with a war against Brandenburg. The invasion of Scania was combined with a simultaneous Norwegian front called the Gyldenløve War, forcing the defending Swedes to fight a two-front war in addition to their entanglements in the Holy Roman Empire.
