波列斯瓦夫一世
From 985, several Princes of the Empire carried out annual campaigns together with the Christian Polish princes Mieszko I and Bolesław I Chrobry to subjugate the area, however these campaigns were unsuccessful. In 1003 King Henry II of Germany tried a different approach: he allied himself with the Lutici and waged war against his previous ally Prince Bolesław of Poland. This stabilized the independence of the Lutici and ensured that the area remained ruled by Polabian Slavs and unchristianized into the 12th century.
