Definition of triple alliance in English English dictionary
1668 alliance of Netherlands England and Sweden against France; 1717 treaty by England France and the Netherlands; 1872 alliance of Austria-Hungary Russia and Germany
(1882) Secret agreement between Germany, Austria-Hungary, and Italy. It provided that Germany and Austria-Hungary would support Italy if it was attacked by France, that Italy would similarly assist Germany, and that Italy would remain neutral if Austria-Hungary was attacked by Russia. The alliance advanced Otto von Bismarck's efforts to isolate France. Conflicts between Italy and Austria-Hungary over their interests in the Balkans led Italy to reach an understanding of neutrality with France in 1902, which effectively nullified Italy's pledge to the members of the Triple Alliance, though the alliance was renewed in 1907 and 1912.

or Paraguayan War (1864/65-70) Bloodiest conflict in Latin American history, fought between Paraguay and the allied countries of Argentina, Brazil, and Uruguay. The Paraguayan dictator Francisco Solano López (1827-70), objecting to Brazil's interference in the politics of neighbouring Uruguay, declared war on Brazil in 1864. The next year Argentina organized the Triple Alliance with Brazil and Uruguay. After three years of fighting, the allies annihilated the Paraguayan forces, but Solano López carried on a guerrilla war until he was killed. Paraguay was devastated by the war; its population was reduced by half, and territory covering some 55,000 sq mi (140,000 sq km) was annexed by Brazil and Argentina
