The balance of power in Europe had been suddenly altered after the German victory over France in 1871. The German empire at this time had powerful economy and military. For Bismarck, this was a challenge due to the sense of revenge from France and the ongoing tensions of Austria-Hungary and Russia over the Balkans. So his primary goal was to isolate France to avoid it from allying with Russia to avoid war on two fronts and to maintain peace in Europe. The loss to Germany in the Franco Prussian war left France humiliated. France wasn’t capable of seeking it’s revenge against Germany alone and knew that an alliance was the only option. And Bismarck realized this too. So for Bismarck, forming an alliance with Russia and Austria was his next priority. But this was complicated as Russia and Austria Hungary have been rivals due to the situation in the Balkan area.
