In 1742 the town, under the Germanized name "Striegau", became part of Prussia. On 4 June 1745 the Battle of Hohenfriedberg, an important victory for King Frederick II against joint Austrian-Saxon-Polish forces during the War of the Austrian Succession, took place near the town. During the Seven Years' War, Austrian and Russian troops occupied the city from 1760 to 1762, causing great suffering to the civilian population. During the Napoleonic Wars and Polish national liberation fights, Napoleonic troops occupied the town on 23 December 1806. In the ensuing three years, the city was forced to make total contributions of 100,000 talers. Polish troops were stationed in the town in 1807, and later also Prussian and Russian troops. During the German Campaign of 1813, Striegau suffered further financial losses and had to feed 5400 officers and 92,400 soldiers from both the Prussian and the French army.
