Charles' death marked the end of autocratic kingship in Sweden, and the subsequent Age of Liberty saw a shift of power from the monarch to the parliament of the estates. Historians of the late 18th and early 19th centuries viewed Charles' death as the result of an aristocratic plot, and Gustav IV Adolf, the king who refused to settle with Napoleon Bonaparte, "identified himself with Charles as a type of righteous man struggling with iniquity" (Roberts). Throughout the 19th century's romantic nationalism Charles XII was viewed as a national hero. He was idealized as a heroic, virtuous young warrior king, and his fight against Peter the Great was associated with the contemporary Swedish-Russian enmity. Examples of the romantic hero idolatry of Charles XII in several genres are Esaias Tegnér's song "Kung Karl, den unge hjälte" (1818), Johan Peter Molin's statue in Stockholm's Kungsträdgården (unveiled on 30 November 1868, the 150th anniversary of Charles' death) and Gustaf Cederström's painting "Karl XII:s likfärd" ("Funeral procession of Charles XII", 1878). The date of Charles' death was chosen by a student association in Lund for annual torch marches beginning in 1853.
