The Hungarians succeeded in extending the "de iure" Bavarian-Hungarian border to the River Enns (until 955), and the principality was not attacked from this direction for 100 years after the Battle of Pressburg. The intermittent Hungarian campaigns lasted until 970, but two military defeats in 955 (Lechfeld) and 970 (Arcadiopolis) marked a shift in the evolution of the Hungarian principality.
