In the first half of the 19th Century population in Europe grows another 40 percent. Increased food production, better medical services and hygiene as well as early marriages result in an increase of birth rates, going along with a decrease of death rates. In 1815 a mass immigration of German clothmakers to Poland followed. At that time, the governmental precinct Posen comprises 26 districts. The increase in German population lasts until 1870 and their settlement finally results in German becoming the official language in the Province of Posen in the 19th Century. One after another, names of villages are „germanized“, which means their spelling is adapted to German language or translated. For example the name of the town ‚Chodziesen‘ , later ‚Chodziez‘ , is translated into ‚Kolmar‘ , ‚ Szamocin ‘ is adapted to read ‚ Samotschin ‘. After WWII, the majority of those villages and towns started re-using their former Polish names.
