Province of Upper Silesia
With the outbreak of World War II (1 September 1939) the town was flooded with refugees from Upper Silesia. In the morning of 3 September Polish local government was evacuated from the town, as well as many residents. The following day, after a number of short skirmishes with the Polish troops, the town was occupied by German troops. In November 1939 when the town with the western half of the county was annexed directly to Nazi Germany, Chrzanów was made a county town in the Katowice region of the Province of Upper Silesia.
