The Triple Alliance was a military alliance among Germany, Austria–Hungary, and Italy. It lasted from 20 May 1882 until World War I in 1914. Each member promised mutual support in the event of an attack by any other great power, or, in the case of 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 the Balkans without previous consultation.
