Italy has acquired almost all the Slovene and Croft districts of Gorizia and Istria.
The entry of Italy into the war was a serious set-back to the Yugoslav cause, for under the Treaty of London (April 27 1915) she was to obtain, in the event of an Entente victory, wide districts in Gorizia, Carniola, Istria and Dalmatia, peopled by not less than 700,000 Yugosla y s.
The facts regarding the Yugoslav legions and the services rendered by Yugoslav deserters at Gorizia and in the Trentino were simply suppressed.
This in turn strengthened the hands of the extreme section among the Yugosla y s, who now advanced the full ethnographic claim, involving Trieste and Gorizia as well as Dalmatia and Istria, and at the same time increased their demands against Bulgaria, Austria and Albania.
It then defined what came to be known as " the Wilson Line," which assigned to Italy Gorizia, Trieste and Istria west of the river Arsa, but not Fiume, which must become an international port, nor any points south of it, save perhaps Lissa and Valona: it also advocated the dismantling of the whole eastern Adriatic coast.
