Battle of Mohi

Battle context

The Battle of Mohi, fought at Muhi southwest of the Sajó River in present-day Hungary, was the decisive engagement of the Mongol invasion of Europe and resulted in a Mongol victory over the Kingdom of Hungary under King Béla IV. Despite commanding a substantially larger force of approximately 80,000 against an estimated 15,000–30,000 Mongol troops under Batu Khan, the Hungarian royal army was destroyed, suffering around 10,000 casualties. The scale of the defeat eliminated Hungary's capacity to mount organized resistance and opened the kingdom to Mongol depredation. The battle's consequences extended beyond Hungary itself. The Mongols' victory was achieved at a cost heavy enough to contribute to the subsequent decision to halt the westward campaign, making Mohi a turning point not only for Hungary but for the broader Mongol invasion of Europe. For Hungary, the destruction of the royal army inaugurated a period of rebuilding and reorganization, while shifting the balance of power in eastern Europe. The engagement stands as one of the most consequential battles in Hungarian history and a defining episode of the Mongol invasions of 1206–1337.
