WORLD HISTORY

Detailed explanation-1: -The Franco-Prussian War or Franco-German War, often referred to in France as the 1870 War (July 19, 1870 – May 10, 1871) was a conflict between France and Prussia, which was backed by the North German Confederation and the South German states of Baden, Württemberg and Bavaria.

Detailed explanation-2: -The immediate cause of the Franco-Prussian War was the candidacy of Prince Leopold of Hohenzollern-Sigmaringen for the Spanish throne, which raised the possibility of a combination of Prussia and Spain against France.

Detailed explanation-3: -In Prussia, a war against France was deemed necessary to arouse German nationalism in those States in order to allow the unification of most German states (excluding the ethnically German lands of the Austrian Empire) into a great German empire.

Detailed explanation-4: -After Austria refused to recall its troops from the French border and to back down on the perceived threat of using force, France declared war on Austria and Prussia in the spring of 1792; both countries responded with a coordinated invasion that was eventually turned back at the Battle of Valmy in September.

Detailed explanation-5: -The third and final act of German unification was the Franco-Prussian War of 1870-71, orchestrated by Bismarck to draw the western German states into alliance with the North German Confederation. With the French defeat, the German Empire was proclaimed in January 1871 in the Palace at Versailles, France.
