Europe
Leaving the Napoleonic period behind, the mid to late 19th Century saw a wide variety of conflicts between most of the nations and states of Europe. In northern Europe, Denmark and Prussian engaged in a war over the Schleswig-Holstein region and Britain, France and Russia clashed in the Crimea. Further south saw Austria, France and Prussia fighting for many years over German plans for unification, whilst the Italian states clashed with Austria over similar issues.
