Battle of Grunwald
Historians have since made progress towards dispassionate scholarship and reconciliation of the various national accounts of the battle.

Poland and Lithuania: The Battle of Grunwald is regarded as one of the most important in the histories of Poland and Lithuania. In Lithuania, the victory is synonymous with the Grand Duchy's political and military peak. It was a source of national pride during the age of Romantic nationalism and inspired resistance to the Germanization and Russification policies of the German and Russian Empires. The Teutonic Order was portrayed as bloodthirsty invaders and Grunwald as a just victory achieved by a small, oppressed nation.
In 1910, to mark the 500th anniversary of the battle, a monument by Antoni Wiwulski was unveiled in Kraków during a three-day celebration attended by some 150,000 people. About 60 other towns and villages in Galicia also erected Grunwald monuments for the anniversary. About the same time, Nobel Prize-winner Henryk Sienkiewicz wrote the novel The Knights of the Cross (Polish: Krzyżacy), prominently featuring the battle in one of the chapters. In 1960, Polish filmmaker Aleksander Ford used the book as the basis for his film, Knights of the Teutonic Order. At the 1939 New York World's Fair, Poland exhibited the King Jagiello Monument which commemorated the battle and was later installed in the Central Park, New York City. The battle has lent its name to military decorations (Order of the Cross of Grunwald), sports teams (BC Žalgiris, FK Žalgiris), and various organizations. 72 streets in Lithuania are named after the battle.

Under Communist rule over Poland, memory to the battle was monopolized by the state. Memory to the battle was instrumentalized for justifying the new borders, under which Poland annexed a quarter of pre-war Germany, while losing the Kresy. Under the new government in the 1970s, anti-German propaganda was reduced, but the symbol of Grunwald did not disappear. Until end of the 1980s, July 15 was an important official memorial day.
An annual battle re-enactment takes place on 15 July. In 2010, a pageant reenacting the event and commemorating the battle's 600th anniversary was held. It attracted 200,000 spectators who watched 2,200 participants playing the role of knights in a re-enactment of the battle. An additional 3,800 participants played peasants and camp followers. The pageant's organisers believe that the event has become the largest re-enactment of medieval combat in Europe. The reenactment attracts about 60,000 to 80,000 visitors annually.

The battle is also commemorated in Ukraine and Belarus. In 2010, the National Bank of Ukraine released a jubilee coin of 20 hryvnia commemorated to the 600 anniversary of the battle. At least three cities in Ukraine (Lviv, Drohobych, and Ivano-Frankivsk) have a street named after the battle. In Belarus, interest in the battle began to grow in the late 1980s and early 1990s. In 2010, Belarus issued postage stamps for the 600th anniversary. Since 2008, Our Grunwald Festival is hosted by a private museum of medieval culture near Minsk and includes battle reenactment.

Germany and Russia: Germans generally saw the Teutonic knights as heroic and noble men who brought Christianity and civilization to the east, although many came to the region with more material motives. In August 1914, during World War I, Germany won a battle against Russia near the site. When the Germans realized its propaganda potential, they named the battle the Battle of Tannenberg, despite it having actually taken place much closer to Allenstein (Olsztyn), and framed it as revenge for the Polish–Lithuanian victory 504 years earlier. To cement this symbolism, Germany built the Tannenberg Memorial, which became the tomb of the national hero Paul von Hindenburg.
Nazi Germany later exploited the sentiment by portraying their Lebensraum policies as a continuation of the order's historical mission. For example, SS Chief Heinrich Himmler told Nazi Germany's leader Adolf Hitler on the first day of the Warsaw Uprising in August 1944: "After five, six weeks we shall leave. But by then Warsaw, the capital, the head, the intelligence of this former 16–17 million Polish people will be extinguished, this Volk that has blocked our way to the east for 700 years and has stood in our way ever since the First Battle of Tannenberg."
Due to the participation of the three Smolensk banners, Russians saw the battle as a victory of a Polish–Lithuanian–Russian coalition against invading Germans. However, the ethnic composition of the men under these banners cannot be determined as Smolensk had rebelled against Vytautas in 1404 and 1408. Chronicler Jan Długosz praised the Smolensk banners, who fought bravely and, according to him, were the only banners from the Grand Duchy of Lithuania not to retreat. In Soviet historiography, the Battle of Grunwald was styled as an ethnic struggle between Slavs and Germanics. The Teutonic Order was portrayed as the medieval forerunners of Hitler's armies, while the battle itself was seen as the medieval counterpart to the Battle of Stalingrad.
In 2014, the Russian Military Historical Society stated that Russian troops and their allies defeated the German knights in the Battle of Grunwald. In July 2017, billboards appeared on the streets of Russian cities with statements that seemed to attribute the victory in the battle of Grunwald to Russia.
