The Franco-German War broke out on July 19th 1870 between France and Prussia following French feelings over Prussia's support for a Hohenzollern prince likely to become king of Spain. South Germany joined with Prussia in the war, while Austria and Italy remained neutral. With the French army in chaos, three German armies invaded France and made great headway resulting in Napoleon giving himself up to the king of Prussia and ending the Second Empire. Revolt shook Paris and the empress fled. A government of National defence was set up which eventually capitulated to the Germans on January 28th 1871 and peace was signed on May the 10th 1871 in which France ceded Alsace- Lorraine, Metz and Strasbourg and a war indemnity of œ200,000, 000 imposed on France.
