Pugna regis karoli Ipe Cassam cum suis contra Mathm i filios Omadri

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