The Battle of Brenta was fought between the cavalry of the Kingdom of Italy under king Berengar I and the Hungarians, hired by the East Francian king Arnulf of Carinthia, against him, at an unidentified location in northern Italian Peninsula along the river Brenta on 24 September 899. It was one of the earliest battles of the Hungarian invasions of Europe. The result was a crushing defeat for Berengar I, opening the following raids for the Hungarians against Italy. The Hungarian invasion resulted in the burning of many cities, like Feltre, Vercelli, Modena and monasteries like the monastery in Nonantola, and attacking even Venice, however without success.
