In his book series "Berättelser ur Svenska historien" (), Anders Fryxell criticized the heroic image of Charles X Gustav, viewing the king's war policy as morally unjust. Wilhelm Erik Svedelius rebuked Fryxell in 1844. Swedelius believed one could not place moral values on the actions of statesmen, arguing the good of the state was synonymous with the morally good. Fryxell gave his response in 1855, comparing Charles X Gustav's attack on Denmark in 1658 with Russia's attack on Sweden in 1808, which led to the loss of Finland.
