The Franco-Russian Alliance, also known as the Dual Entente or Russo-French Rapprochement, was an alliance formed by the agreements of 1891–94; it lasted until 1917. The strengthening of the German Empire, the creation of the Triple Alliance of 1882, and the exacerbation of Franco-German and Russo-German tensions at the end of the 1880s led to a common foreign policy and mutual strategic military interests between France and Russia. The development of financial ties between the two countries created the economic prerequisites for the Russo-French Alliance.

The Triple Entente describes the informal understanding between the Russian Empire, the French Third Republic, and the United Kingdom of Great Britain and Ireland. It was built upon the Franco-Russian Alliance of 1894, the Entente Cordiale of 1904 between France and Britain, and the Anglo-Russian Entente of 1907. It formed a powerful counterweight to the Triple Alliance of the German Empire, the Austro-Hungarian Empire, and the Kingdom of Italy. The Triple Entente, unlike the Triple Alliance or the Franco-Russian Alliance itself, was not an alliance of mutual defence.
