In 900, during the Hungarian invasions of Europe, the Magyar army ravaged Bavaria. Another group of Magyars were defeated by Luitpold, Margrave of Bavaria and Bishop Richer of Passau. In 901 they devastated the Duchy of Carinthia. In 904 Louis invited Kurszán, the kende of the Magyars, to negotiations, but killed him and his delegation. In 906 Magyars twice ravaged the Duchy of Saxony. In 907 they inflicted a heavy defeat on the Bavarians who had invaded Hungary, killing the Margrave Luitpold and many high nobles in the Battle of Pressburg. Next year it was the turn of Saxony and Thuringia, and in 909 that of Alemannia. On their return, however, Arnulf, Duke of Bavaria inflicted a defeat on them on the river Rott, but in 910 they, in their turn, defeated Louis the Child's army in the Battle of Augsburg. Louis himself tried to take some military control as he grew older, but he had little success against the Magyars. His army was destroyed at Ennsburg in 907.
