The Triple Alliance was the military alliance among Germany, Austria–Hungary, and Italy, (as opposing the Triple Entente which consisted of an alliance between Britain, France and Russia), that lasted from 1882 until the start of World War I in 1914. Each member promised mutual support in the event of an attack by any other great power, or for Germany and Italy, an attack by France alone. In a supplementary declaration, Italy specified that its undertakings could not be regarded as being directed against Great Britain. Shortly after renewing the Alliance in June 1902, Italy secretly extended a similar guarantee to France. By a particular agreement, neither Austria–Hungary nor Italy would change the Status quo in Balkan area without a previous consultation.
