Franco-Russian Alliance
Bismarck had supported France becoming a republic in 1871, knowing that this would isolate the defeated nation in Europe where most countries were monarchies. In an effort to break this isolation, France went to great pains to woo Russia and the United Kingdom to its side, first by means of the Franco-Russian Alliance of 1894, then the 1904 "Entente Cordiale" with the U.K, and finally, with the signing of the Anglo-Russian Entente in 1907 this became the Triple Entente, which eventually led France and the UK to enter World War I as Allies when Germany declared war on Russia.
