Parallels are demonstrated between changes in Swedish attitudes toward
peace and war, reflected in the image of the the 'war-hero', Karl XII
, and the increasing peacefulness of Swedish society. The value change
s are documented through analyses of four literary works: those of Gei
jer and Tegner, who glorified Karl XII as 'war-hero', and Heidenstam a
nd Strindberg, who described the same Karl XII as a psychopath and vil
lain and as a scourge for his country. As Geijer and Tegner wrote at t
he beginning of the 19th century, whereas Heidenstam and Strindberg pr
oduced their works at the end of it, the value changes occurring durin
g this century can be demonstrated in these literary works. Relations
between changed mentalities, as reflected in the literary works, and p
olitical decisions are explored Finally, as a resulting implication, t
he potential impact of critical attitudes of the electorate on a leade
r's election and on his license for engaging in impulsive wan is discu
ssed.
