This work covers the Franco-Prussian War which broke out in 1870 when Bismarck engineered a war with the French Second Empire of Napoleon III. This was part of his wider political strategy of uniting Prussia with the Southern German Confederation & excluding Austria. The war was an overwhelming Prussian victory & the king was proclaimed Emperor of the new united Germany. The Second Empire collapsed & Napoleon III fled in exile to Britain. In the clearing up operation against the French Third Republic Germany gained the eastern French provinces of Alsace & Lorraine areas that were to provide a bone of contention for years to come.
