The Triple Alliance was formed by Bismarck, after the Franco-Prussian
War. Its object was to strengthen Germany and isolate France. A dual
league was made in 1879 between Austria and Germany, which Italy joined
in 1880. By this alliance the nations intended to aid each other in
defense. Bismarck wanted Russia in the league, but trouble in the
Balkans broke off this project.
Soon after France formed a league with Russia. Bismarck fell from power
in 1890, but the Triple Alliance was still stronger than its rival,
until France brought England into the Triple Entente, agreeing to give
England a free hand in Egypt in return for the same in Morocco.
