In 955, on this day the forces of Otto the Great, King of the Germans were defeated at the Battle of Lechfeld. Perhaps the best opportunity for holding off the incursions of the Magyars into Central Europe was lost. This defining event in European history was a decisive victory for the Magyar leaders, namely the harka (military leader) Bulcs? and the chieftains Lel (Lehel) and S?r who continued to rage unchecked across the continent.
