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.
