However, Christian Frederick was unable to secure international support, as the Great Powers, in particular Britain, wished to reward Sweden for its support against Napoleonic France and to compensate it for the loss of Finland to Russia, and therefore desired to see the Treaty of Kiel enforced. In a short war in summer 1814, Swedish troops invaded Norway and expelled Christian Frederick (who later became King Christian VIII of Denmark).
