 This episode from the Lithuanian Crusade was popularized during the 19th-century wave of romantic nationalism and Margiris is treated as a national hero in Lithuania.Very little is known about Margiris' life.In primary written sources his name is mentioned only twice, in 1329 as "Margalis" by chronicler Jean d'Outremeuse in "Ly myreur des histors" and as "Marger" in 1336 by Caspar Schütz in "Historia Rerum Prussicarum".
