The Kingdom of Italy claimed all of the territory which covers present-day Italy and even more. The development of the Kingdom's territory progressed under Italian re-unification until 1870. The state for a long period of time did not include Trieste or Trentino-Alto Adige/Südtirol, which were annexed in 1919 and remain Italian territories today. The Triple Entente promised to grant to Italy – if the state joined the Allies in World War I – several territories including former Austrian Littoral, western parts of former Duchy of Carniola, Northern Dalmazia and notably Zara, Šibenik and most of the Dalmatian islands (except Krk and Rab), according to the secret London Pact of 1915.
