After their defeat at the 955 Battle of Lechfeld, the Magyars had discontinued their attacks on Germany and settled in the former Roman province of Pannonia, where they established the Kingdom of Hungary. The adjacent territories west of the Leitha were incorporated as the March of Styria into the Holy Roman Empire. In 1180 Emperor Frederick Barbarossa raised the Styrian lands to a duchy, which in 1192 was acquired by the Austrian dukes from the House of Babenberg.
