East Francia
In fact, following a break of eleven years, the Hungarians returned to the Carpathian Basin in 892. They came to assist Arnulf of East Francia against Svatopluk I of Moravia. Widukind of Corvey and Liutprand of Cremona condemned the Frankish monarch for destroying the defense lines built along the empire's borders, because this also enabled the Hungarians to attack East Francia within a decade.
