The French Emperor, Napoleon III, feared that a strong Prussia would upset the balance of power in Europe. Bismarck, at the exact same time, sought war with France; he believed that if the German nations perceived France as the aggressor, they would unite behind the King of Prussia.
A appropriate premise for war arose in 1870, when the German Prince Leopold of Hohenzollern-Sigmaringen was offered the Spanish throne, which had been vacant since a revolution in 1868.
The publication was meant to provoke France into declaring war on Prussia. France mobilized and declared war, but was viewed as the aggressor; as a consequence, German states, swept up by nationalism and patriotic zeal, rallied to Prussia’s side and supplied troops.
The Franco-Prussian War in 1870 was a terrific success for Prussia. The German army, controlled by Moltke, won victory after victory. The French were defeated in every battle. The rest of the war featured quite cautious German operations and massive confusion on the part of the French.
In the end, France was forced to pay a huge indemnity and concede Alsace and part of Lorraine. Though Bismarck opposed the annexation, asserting it would be the”Achilles’ Heel” of this new empire, Moltke and his generals insisted that it was needed to keep France in a defensive position. He broke France’s supremacy over continental Europe following the Franco-Prussian war.
He carefully built the outside safety of the new German Country upon his skillful diplomacy, which circulated France globally and made a vast and intricate system of alliances for mutual military support with the majority of Europe’s states.
In the use of an’honest broker’, Bismarck was also effective in preserving peace and stability in Europe by settling French political conflicts through negotiations. Basically a careful politician, Bismarck never chased an imperialistic course in Europe. In Africa however, Bismarck followed for a time a policy of imperial conquest, in a way similar to the other European powers.
His most important tool in politics was his ability in the successful preparation of complex international developments.
Bismarck decided to act immediately to secure the unification of Germany after his victory over France. He opened negotiations with representatives of European states, offering special concessions if they would agree to unification. The negotiations were successful; King Wilhelm was crowned”German Emperor” on 18 January 1871 in the Hall of Mirrors in the Chateau de Versailles for the additional humiliation of France.
