A doctored telegram helped birth the German Empire
The Franco-Prussian War—also called the Franco-German War or France’s War of eighteen seventy—pitted France against Prussia’s North German Confederation from nineteen July eighteen seventy to twenty-eight January eighteen seventy-one. France wanted to reclaim continental primacy after Prussia’s eighteen sixty-six thrashing of Austria.
When Prince Leopold of Hohenzollern-Sigmaringen accepted then withdrew from the vacant Spanish throne, the French ambassador pressed King Wilhelm I at Ems to renounce future claims; Wilhelm refused. The Ems Dispatch of thirteen July reached Berlin; Chancellor Otto von Bismarck published an altered wording that inflamed Paris. Some historians say he meant to force war so Baden, Württemberg, Bavaria, and Hesse-Darmstadt would join the North; others say he exploited events—agreement that he saw alliance potential either way.
France mobilized on fifteen July; the Confederation answered the same day. Parliament declared war on sixteen July; French troops crossed on two August, but German forces invaded northeastern France on four August with superior numbers, training, leadership, and modern kit. Victories climaxing during Metz's investment and the Sedan clash captured Emperor Napoleon III and wrecked the Second Empire’s army; a Government of National Defense formed in Paris on four September and fought five more months through a long siege.
With victory assured, German states proclaimed the German Empire under Wilhelm I, uniting most German-speakers except Austria and Swiss Germans for the first time. The Treaty of Frankfurt on ten May eighteen seventy-one extracted billions of francs in indemnity plus most of Alsace and part of Lorraine—binding battlefield humiliation to a new great power on the map.
Paris itself held out under siege for more than four months before falling on 28 January 1871. France had gone in almost friendless, gambling that a quick offensive would coax Austria, Italy and Denmark to its side, while German armies exploited railways and artillery far better. Bismarck later boasted that the edited telegram worked on French opinion like a red flag waved at a bull, and the monarchist Adolphe Thiers, who argued France had already won the diplomatic contest, was shouted down as a traitor. The consequences outlasted the fighting: imperial rule in France ended for good, a lasting republic began, and anger at the defeat fuelled the Paris Commune, which held power for two months before being crushed.
