At the end of World War I, the Austrian Empire disintegrated, and Dalmatia was again split between the Kingdom of Serbs, Croats and Slovenes (later the Kingdom of Yugoslavia) which controlled most of it, and the Kingdom of Italy which held small portions of northern Dalmatia around Zadar and the islands of Cres, Lošinj, and Lastovo. Italy entered World War I in a territorial gamble, mostly to gain Dalmatia. But Italy got only a small part of its pretensions, so Dalmatia mostly stayed Yugoslav until Benito Mussolini invaded Yugoslavia in 1941 and occupied the region.
