The Battle of Grunwald took place on July 15, 1410 with king Jogaila (Władysław II Jagiełło) leading the Kingdom of Poland and the Grand Duchy of Lithuania in alliance against the knights of the Teutonic Order who were led by the Grand Master Ulrich von Jungingen. The engagement in the Polish-Lithuanian-Teutonic War (1409-1411) was one of the most important battles in Medieval Europe, and the largest battle to involve knights.

The forces of the Monastic State of the Teutonic Knights were decisively defeated in the battle, but were able to defend their castles and retain most of their territories despite the long-term consequences they suffered as a result of losing the battle. The order never recovered its former power, and the financial burden of the ensuing reparations eventually caused a rebellion of cities and landed gentry.
