King Charles X of Sweden

The Northern Wars (1655-1661) is a name sometimes used for the series of conflicts between Sweden and its adversaries Polish-Lithuanian Commonwealth (The Deluge, 1655-1660), Russia (1656-1661), Brandenburg-Prussia (1657-1660), the Holy Roman Empire (1657-60) and Denmark (1657-1658, 1658-1660). The same wars are sometimes referred differently in other countries: for example in Poland The Deluge sometimes is a name for the series of wars against Sweden, Brandenburg, Russia, Siebenbürgen and Cossacks. In these conflicts Great Britain was consistently an ally of Sweden whereas the Republic of the Seven United Netherlands often intervened against the Swedes.
