The Battle of Rozgony or Battle of Rozhanovce is fought between King Charles I of Hungary and the family of the late Palatine Amade Aba on June 15, 1312, on the Rozgony (today Rozhanovce) field.
Chronicon Pictum describes it as the "most cruel battle since the Mongol invasion of Europe".
Despite many casualties on the King's side, his decisive victory brings an end to the Aba family's rule over the eastern Kingdom of Hungary, weakens his major domestic opponent Máté Csák III, and ultimately secures power for Charles I of Hungary.
