It was an internal conflict between Solomon, King of Hungary and his cousins duke Géza and Ladislaus, who were claiming rights to the throne.

Solomon ruled for a few years, during which he allegedly submitted the country to the Holy Roman Empire as a vassal state to ensure his power over the kingdom at fear of his relatives usurping the throne.

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.

The princes decided to settle this in a battle and it ended favorably for them thanks to the assistance of Otto I of Brno[1] 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.
