Triple Entente, an informal alliance among Great Britain, France, and Russia in the period before World War I. It opposed the Triple Alliance of Germany, Austria-Hungary, and Italy. The Triple Entente was based on three bilateral agreements. The Dual Alliance (1894) between France and Russia was a political and military alliance; each nation promised to support the other in the event of an attack by one or all of the members of the Triple Alliance. The Entente Cordiale (1904) settled a number of disputes between France and Great Britain, clearing the way for closer Anglo-French cooperation. In 1907 Britain and Russia negotiated a similar agreement. After World War I broke out, the Entente powers signed a formal military alliance. They fought together until 1917, when Russia withdrew from the war.
Gallipoli Campaign, an Allied attempt in 1915, during World War I, to seize the Gallipoli Peninsula in Turkey and thus gain control of the Dardanelles strait, opening a supply route from the west to Russia through the Black Sea.
