  As the result of Ostsiedlung, less populated regions of Central Europe (i.e. sparsely populated border areas in present-day Poland and Czechia) received a significant number of German speakers. Silesia became part of the Holy Roman Empire as the result of the local Piast dukes' push for autonomy from the Polish Crown. From the late 12th century, the Duchy of Pomerania was under the suzerainty of the Holy Roman Empire and the conquests of the Teutonic Order made that region German-speaking.
