The Battle of Durbe was a medieval battle fought near Durbe, 23 km (14 mi) east of Liepāja, in present-day Latvia during the Livonian Crusade. On 13 July 1260, the Samogitians soundly defeated the joint forces of the Teutonic Knights from Prussia and the Livonian Order from Livonia. Some 150 knights were killed, including Livonian master Burkhard von Hornhausen and Prussian land marshal Heinrich Botel. It was by far the largest defeat of the knights in the 13th century: in the second-largest, the Battle of Aizkraukle, 71 knights were killed. The battle inspired the Great Prussian Uprising and the rebellions of the Semigallians, the Couronians, and the Oeselians. The battle undid two decades of Livonian conquests and it took some thirty years for the Livonian Order to restore its control.
