Treaty of Frankfurt

The Treaty of Frankfurt, signed on May 10, 1871, ended the Franco-Prussian War between France and the German states led by Prussia. It marked the unification of Germany and imposed heavy reparations on France, including the loss of the provinces of Alsace and Lorraine. This treaty significantly altered the balance of power in Europe, leading to German dominance and increasing tensions with France, which sought to regain its lost territories. The treaty is often seen as a precursor to future conflicts, particularly World War I, due to its harsh terms and national resentments it fostered.
