The Battle of Rozgony took place in 1312, during a turbulent period in Hungary marked by a power struggle between King Charles I and the noble factions led by Amade Aba. Charles I, a member of the Anjou dynasty, had ascended to the throne amidst considerable opposition, particularly from the powerful Aba family, who were prominent landowners and had significant influence in the region. The conflict emerged from issues surrounding feudal rights and regional control, as the nobility pushed back against the king's attempts to centralize authority.

As tensions escalated, Charles I mobilized his forces to confront the Aba faction. The battle occurred at Rozgony, a strategic location where the king's troops engaged the rivals. Utilizing superior tactics and a well-trained army, Charles I effectively outmaneuvered the Aba forces. Reports indicate that the battle was marked by fierce fighting, but ultimately the royal forces claimed victory, capturing key members of the Aba family and diminishing their power.

This decisive victory not only reaffirmed Charles I's position on the Hungarian throne but also initiated a shift in the balance of power among the nobility. Following this battle, the influence of the Aba family waned significantly, allowing Charles to pursue his policies of centralization and consolidation of power. This event proved pivotal in Charles I's reign, marking the decline of the Aba family's political influence and strengthening the authority of the crown in Hungary.
