1701–1721: Plague and the Great Northern War
The Kingdom of Prussia was still recovering from the devastation of the Thirty Years' War and poor in natural resources. Its territory was disjointed, stretching from the lands of the Duchy of Prussia on the south-east coast of the Baltic Sea to the Hohenzollern heartland of Brandenburg, with the exclaves of Cleves, Mark and Ravensberg in the Rhineland. In 1708 about one third of the population of the Duchy of Prussia died of bubonic plague. The plague reached Prenzlau in August 1710 but receded before it could reach the capital Berlin, which was only away.

The Great Northern War was the first major conflict that the Kingdom of Prussia was involved in.

Kingdom of Prussia [SEP] 1701–1721: Plague and the Great Northern War
Starting in 1700, the Great Northern War involved a coalition led by Tsarist Russia against the dominant North European power at the time, the Swedish Empire. Frederick William in 1705 tried to get Prussia involved in the war, stating it "best Prussia has her own army and make her own decisions." His views, however, were not considered acceptable by those in power. It was not until 1713 that Frederick William gained full royal powers. Therefore, in 1715, Prussia, led by Frederick William, joined the coalition for various reasons, including the danger of being attacked from both her rear and the sea; her claims on Pomerania; and the fact that if she stood aside and Sweden lost she would not get a share of the territory.
