The Livonian Order suffers its greatest defeat in the 13th century in the Battle of Durbe against the Grand Duchy of Lithuania
Military activities of the Teutonic Knights in the 13th century
The Battle of Durbe was a medieval battle fought near Durbe, 23 km 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 Livonian Order from Livonia. 150 knights were killed including Livonian Master Burchard von Hornhausen and Prussian Land Marshal Henrik Botel. It was by far the largest defeat of the knights in the 13th century: in the second-largest Battle of Aizkraukle 71 knights were killed. The battle inspired the Great Prussian Uprising (ended in 1274), rebellion of the Semigallians (surrendered in 1290) and the Couronians (surrendered in 1267). The battle undid some 20 years of Livonian conquest and it took some thirty years for the Livonian Order to restore its control.
