When this agreement was signed, the dissolution of Austria-Hungary was not in contemplation, or at least, if it was considered, the possibility of its accomplishment seemed very remote. It was assumed that the Dalmatian territory to be acquired under the treaty to be negotiated in accordance with the terms of the Pact would, with the return of the Italian provinces, give to Italy naval control over the Adriatic Sea and secure the harborless eastern coast of the Italian peninsula against future hostile attack by the Austro-Hungarian Empire. The boundary laid down in the agreement was essentially strategic and based primarily on considerations of Italian national safety. As long as the Empire existed as a Great Power the boundary of the Pact of London, so far as it related to the Adriatic littoral and islands, was not unreasonable or the territorial demands excessive. But the close of active warfare in the autumn of 1918, when the armistice went into effect, found conditions wholly different from those upon which these territorial demands had been predicated. The Austro-Hungarian Empire had fallen to pieces beyond the hope of becoming again one of the Great Powers. The various nationalities, which had long been restless and unhappy under the rule of the Hapsburgs, threw off the imperial yoke, proclaimed their independence, and sought the recognition and protection of the Allies. The Poles of the Empire joined their brethren of the Polish provinces of Russia and Prussia in the resurrection of their ancient nation; Bohemia, Moravia, and Slovakia united in forming the new state of Czecho-Slovakia; the southern Slavs of Croatia, Slavonia, Bosnia, Herzegovina, and Dalmatia announced their union with their kindred of the Kingdom of Serbia; and Hungary declared the severance of her political union with Austria. In a word the Dual Empire ceased to exist. It was no longer a menace to the national safety of Italy. This was the state of affairs when the delegates to the Peace Conference began to assemble at Paris.
