In 1742 the settlement was annexed by Prussia and from 1871 to 1922 it was part of Germany. Both parts of Świętochłowice merged in 1790. In the 19th and first part of the 20th century the area rapidly industrialized (based on the numerous local resources, including coal and zinc), leading to the transformation of the village into an industrial settlement. In the early 20th century numerous Polish organizations were established there. During the Silesian Uprisings the present-day districts Lipiny and were captured by the Polish insurgents in 1920. In the 1921 Upper Silesia plebiscite, in Świętochłowice 51.9% voted for Germany, while in Chropaczów 70.0% voted for Poland, and in Lipiny and Piaśniki combined 56.4% voted for Poland. In 1922 all named settlements were integrated with the re-established Polish state. In 1929 Zgoda became part of Świętochłowice as its new district. In 1939 Świętochłowice was granted city rights with effect from January 1, 1940, however, due to outbreak of World War II, the actual implementation of this law did not take place until 1947.
