Treaty of Frankfurt
10 May 1871 — Under the Treaty of Frankfurt, France gives up Alsace and most of Lorraine and must pay an indemnity of five billion francs. German troops are to remain on French soil until the debt is paid. France pays it early, by September 1873, but the loss of the provinces remains unacceptable to it.

The moment in context
Bismarck wanted Germany to belong to the larger group in a Europe of five great powers. France had lost Alsace and Lorraine to Germany in 1871; if it found a strong partner, it might try to recover them by force. Germany therefore needed good relations with both Austria-Hungary, the Habsburg empire ruled from Vienna, and Russia. In 1873 the three emperors formed a league to consult and preserve peace. Their interests were hardest to reconcile in the Balkans, where both Austria-Hungary and Russia sought influence as the Ottoman Empire, ruled from Constantinople, retreated. Russia’s victory over the Ottomans in 1878 seemed likely to give it a large client Bulgaria. The powers reduced Bulgaria at the Congress of Berlin, and Russia blamed Germany. Bismarck then made a choice that complicated his own task: the secret Dual Alliance of 1879 promised Austrian defense against Russia. Italy joined in 1882, creating the Triple Alliance.
