Crusenstolpe obtained a great influence over King
Charles XIV, who during the years 1830 to 1833 gave him his fullest confidence, and sanctioned the official character of Crusenstolpe's newspaper
Fäderneslandet. In 1833, however, the historian suddenly became the king's bitterest enemy, and used his acrid pen on all occasions in attacking him. In 1838 he was condemned for one of these angry utterances to be imprisoned three years in the
Vaxholm Castle on the charge of
lèse-majesté, culminating in the
Rabulist riots. He continued his literary labours until his death in 1865. Few Swedish writers have wielded so pure and so incisive a style as Crusenstolpe, but his historical work is vitiated by political and personal bias. ==Works==
