Describe the situation which led to the outbreak of war
The war between France and Prussia (the future German Empire) that lasted from 1870 to 1871 ended with a humiliating defeat for France. It lost the regions of Alsace and Lorraine, and was forced to pay a huge indemnity to Prussia. The Franco-Prussian War led to creation of a powerful German Empire with a military and industrial potential to further disrupt the European balance of power on the one hand and widespread resentment and desire for revenge among the French (revanchism) on the other. Hope this helps.
