Political map of Europe & the Mediterranean 10 May 1871 (Treaty of Frankfurt): With the end of the Franco-Prussian War (Franco-Prussian War), Bismarck (Bismarck) forced France to cede Alsace-Lorraine and pay an indemnity of 5 billion francs (Treaty of Frankfurt (1871)). Germany was now the premier power of Europe.    France's struggle, however, was not yet over. At the end of the war, the people of Paris had risen up and proclaimed a Commune (Paris Commune). This led to a second siege of Paris, this time by the French government. Although the Commune was crushed, it would provide inspiration for the revolutions of the next century.
