 The Magyars returned to Central Europe in July 892 , when they invaded Moravia in alliance with Arnulf , king of East Francia . Two years later , they stormed into the March of Pannonia . According to the Annals of Fulda , they " killed men and old women outright , and carried out the young women alone with them like cattle to satisfy their lusts " . Although this source does not refer to an alliance between the Magyars and Svatopluk I of Moravia , most historians agree the Moravian ruler persuaded them to invade East Francia . During their raids in the Carpathian Basin , the Magyars had several opportunities to collect information on their future homeland .
