The late 13th century saw the election of Rudolf I of the House of Habsburg to the German throne, and the Habsburg family would continue to play an important role in German history for centuries afterwards. They competed for power in the German lands with several noble families, most notably the Limburg-Luxemburg dynasty and the House of Wittelsbach. During the 13th century, the Teutonic Knights began conquering the Old Prussians, and established what would eventually become the powerful German state of Prussia.
