One of the largest battles of medieval Europe took place on July 15, 1410 between the army of the Teutonic order, supported by western European knights, and the combined forces of Poland and Lithuania led by the king of Poland Wladyslaw II Jagiello. The war ended with the victory of the Polish-Lithuanian armies and a rout of the Teutonic forces. Every year on the anniversary of these centuries' events a reconstruction of the battle takes place.
