Prior to World War I the border between Italy and Austria ran from Mount Matajur to Canin, then along the ridge towards Cima Confine and down east from Sella Nevea past the Rio del Lago valley, then along the main crest of Mount Cregnedùl up to the top of the Montasio, down the Somdogna Saddle to finally reach Pontebba. Between the two World Wars, the Eastern Julian Alps were under the dominion of Italy and so was the most part of the Western ones: the political border ran along the Ponze range from the Ratece Saddle to Mount Jalovec, along Site and Mojstrovske mountains upwards to Mount Prisojnik, to Mounts Kriz and Luknja and finally the Tricorno; the whole valley of the Isonzo river was in the Italian territory.
