The Franco-Prussian War was not a large scale war in terms of its casualties, engagements, or scale. It was massive in the geopolitical results in the aftermath of the war, however, and a large reason was that it ended with a months long siege of Paris. Before that siege had even begun, the Empire of France had lost its Emperor, Napoleon III, after he lost the Battle of Sedan. Now France was facing a large Prussian Army staring down its capital, while its government was a provisional one known as the Government of National Defense. This government tried its best to hold on, but also was trying to argue for peace. Eventually, after a few small skirmishes on the outskirts of Paris, the leaders of the French government agree to Armistice terms with Otto von Bismarck, newly christened Chancellor of Germany. The former King of Prussia had also been turned into the German Kaiser, gaining acclaim and territory as the French have to rebuild a Republican government.
