波列斯瓦夫一世
During the rivalry between the Přemyslid dukes Boleslaus III and Jaromir in 1003, the Polish king Bolesław I Chrobry invaded Bohemia, but had to pull back the next year, facing the forces of King Henry II of Germany. In turn the Bohemian duke Bretislaus I campaigned the adjacent northern territory of Silesia after Bolesław's death in 1025. An armistice mediated by Henry II, Holy Roman Emperor since 1014, demarcated the spheres of influence, leaving the area around Kłodzko with Bohemia.
