One of them, Friedeck, had a mostly Czech population, the other three were mostly inhabited by Poles.[2] During the 19th century the number of Germans grew. After decline at the end of the 19th century,[3] at the beginning of the 20th century and later from 1920 to 1938, the Czech population grew significantly (mainly as a result of immigration and the assimilation of locals) and Poles became a minority, which they are to this day. Another significant ethnic group were the Jews, but almost the entire Jewish population was exterminated during World War II.
