After a series of campaigns directed against the Byzantine Empire, which were led by Duke Géza and Ladislaus, Solomon grew bitter and felt unappreciated because of their success on the field. This provoked numerous actions of the king on their expense and was eventually followed up by attempts of murder. The princes decided to settle this in a battle and it ended favorably for them thanks to the assistance of Otto I of Brno and his forces, who was married to Euphemia, one of the sisters of Ladislaus and Géza.

The injured king fled to Germany soon after the battle and there he aimed to regain the crown with the help of his son-in-law. The outcome of this battle overjoyed all of the nation, since it was regarded as a decisive victory for Hungary's statehood.

Thereafter, Solomon preserved only Moson and the nearby Pressburg (Bratislava, Slovakia). Other parts of the kingdom accepted the rule of Géza, who had been proclaimed king after his victory.
