With Johann of Luxemburg becoming King of Bohemia in 1310 marrying Elisabeth of Bohemia, the daughter of Wenceslaus and Judith of Hapsburg, a large retinue of Luxemburgers followed him to Bohemia, therefore, some of our German Bohemian Roots lead towards Luxemburg. Johann of Luxemburg and Judith of Hapsburg were the parents of Kaiser Karl IV, who was the most progressive King of Bohemia and later Emperor of the Holy Roman Empire of the German Nations. His development of our homeland brought a great influx of German craftsmen into Bohemia to completely rebuild and settle around Prague (much the way it is now) . Karl IV is equally important to Germans and Czechs alike, both revering him as "unser Kaiser" or "Náš císař" (nas cisar) .
