This is an introduction to the Franco-Prussian War, a war that marked the beginning of the creation of modern Europe. The Franco-Prussian War started in 1870 when Otto von Bismarck engineered a war with the French Second Empire under Napoleon III, as part of his plan to unite Prussia with the southern German states as a new Germany. Stephen Badsey examines the build-up, battles, and impact of the war, which was an overwhelming Prussian victory with massive consequences. The French Second Empire collapsed, Napoleon III became an exile in Britain, and King Wilhelm I was proclaimed Emperor of the new united Germany. In the peace settlement that followed, Germany gained the eastern French provinces of Alsace and Lorraine, areas that were to provide a bone of contention for years to come. Updated for the new edition with revisions from the author, this is an accessible introduction to the largest and most important war fought in Europe between the age of Napoleon and the First World War.
