In the early 10th century, Hungarian tribes under the Árpád dynasty expanded into Pannonian territories, contesting control of regions including Slavonia along the Drava River. Byzantine sources indicate Hungarian dominance in the area, setting the stage for conflict with the Croatian state led by Tomislav.
According to the late 12th-century Chronicle of the Priest of Dioclea, the Croatian army under Tomislav clashed with Hungarian forces led by Grand Prince Zoltán on the right bank of the Drava River in 925. Tomislav reportedly defeated the Hungarians, though the account's reliability is disputed due to its late composition and lack of corroborating earlier records.
Following the battle, the Duchy of Croatia and the territory of Lower Pannonia were unified, consolidating Croatian territorial authority in the region. However, the historical reality of this unification remains debated, as Byzantine sources suggest continued Hungarian control over Slavonia at the time.
