The Battle of Grunwald is a painting by Jan Matejko depicting the Battle of Grunwald and the victory of the allied Crown of the Kingdom of Poland and Grand Duchy of Lithuania over the Teutonic Order in 1410. The canvas dates to 1878 and is one of the most heroic representations of the history of Poland. It is displayed in the National Museum in Warsaw.
The painting's main focus is the death scene of the Grand Master of the Teutonic Order, Ulrich von Jungingen; another central figure is the Lithuanian duke Vytautas (Witold), dressed in red with a raised sword. The painting has been both hailed and criticized for its complexity. It is one of Matejko's most recognizable works, and has likely contributed to the popular image of the battle of Grunwald, and its enduring fame in Polish consciousness.
