After a brief respite at the end of the Napoleonic period, it wasn't long before conflict hit the western world again, with major wars on both sides of the Atlantic. In Europe, ill-feelings from previous conquests and treaties led to renewed aggression on several fronts, while a divided USA fought against both itself and the native American people. Each of these conflicts drastically changed the landscape of power and influence in a world largely dominated by European colonialism and their collective impact shaped our world forever.
The 19th Century in America saw a wide variety of conflicts, from the more well-known American Civil War and long-running 'Indian Wars' against the native tribes, through to the lesser gamed War of the Pacific, or the Canadian Fenian Raids.
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.
