What impact did the influx of German immigrants have on the Czech Republic?

In order to increase the revenue of the national treasury, the Czech king also allowed a large number of German businessmen and craftsmen to enter the Czech Republic, and allowed the establishment of various autonomous cities with various privileges. Due to a large number of German immigrants, a special social group composed of German feudal lords, urban nobles and mine owners has formed in the Czech Republic. They colluded with the Czech feudal landlords and exploited the Czech people. Farmers and urban civilians, under the double oppression of nationality and class, "live in their own country like exiles".
