After the Silesian Wars, the city came under the rule of Prussia in 1743. Leobschütz was incorporated into the Province of Silesia by 1815 and became the administrative seat of a "Landkreis" (district). In 1781, the town's population stood at only, 2,637. In order to accommodate the city's expansion, parts of the city's wall were torn down. The population stood at 4,565 in 1825, and 9,546 in 1870. After World War I and the creation of the Republic of Poland, the Silesian plebiscite was held in Upper Silesia. The percentage of 99.5% of Leobschütz citizens voted for Germany. The Silesian Uprisings did not directly affect the city, which had almost exclusively German-speaking inhabitants.
