organized separately for Poles and Germans in 1936, the Polish service enjoyed a greater attendance, however, due to Nazi oppression and propaganda, the attendance at Polish services in the 1930s gradually decreased, according to Bund Deutscher Osten. Polish activists were increasingly persecuted since 1937. People were urged to Germanise their names, Polish inscriptions were removed from tombstones. Some Polish priests were expelled from the city, both before and during World War II. As a result of German persecution the Jewish community dropped from 1,154 people in 1933 to 551 in 1939, and its remainder was deported to concentration camps in 1942. The town's synagogue, that had stood since 1872, was destroyed in the Kristallnacht pogroms of November 1938. World War Two During World War II, in 1941 the German administration requisitioned church property, in which it removed Polish symbols and memorabilia. Church bells were confiscated for war purposes in 1942. The Germans established three forced labour subcamps of the Stalag VIII-B/344 prisoner-of-war camp in the city, two of which operated in the local coal mines, and also a subcamp of Auschwitz III was located there. Another subcamp of Stalag VIII-B/344 (E51) was operated at a coal mine in the present-day Mikulczyce district.

The first post-war mayor of Zabrze was Paweł Dubiel, pre-war Polish activist and journalist in Upper Silesia, prisoner of the Dachau and Mauthausen concentration camps during the war.
