レヒフェルトの戦い
Later during the 9th century, the region was contested between Eastern Frankish Kingdom and Great Moravia, while at the very beginning of the 10th century it was invaded and conquered by the Magyars. After the Battle of Lechfeld (955), territories along the river Danube, from the river Enns to the Vienna Woods, were reconquered by Germans, and new march was established (c. 972) thus creating the nucleus of the Margraviate of Austria.
