In late March 1941, when Yugoslavia signed the
Tripartite Pact, Furlan was evacuated from the country with the help of the British intelligence service with which he had established a collaboration. After the
Axis invasion of Yugoslavia and the
Italian occupation of Slovenia, he was convicted to death
in contumaciam by the Italian authorities. After a short stay in
Palestine, Furlan travelled to the
United States. Together with the
liberal conservative Slovenian émigré politicians
Izidor Cankar and
Franc Snoj, Furlan propagated for the Yugoslav and Slovene cause. In 1942, he published a brochure titled
Fighting Yugoslavia: The Struggle of the Slovenes, in which he articulated, among other, the Slovenian claims for the annexation of his native
Julian March region to Yugoslavia. In 1943, he moved to London, where he served as Minister of Education in the
exile government of
Miloš Trifunović between June and August 1943. In the first years of the war, Furlan supported the
Chetnik resistance movement of
Draža Mihajlović, but after early 1944, he became supportive of
Josip Broz Tito's
Yugoslav Partisans. After the Yugoslav Prime Minister
Ivan Šubašić recognized the partisan movement in June 1944, Furlan replaced
Alojzij Kuhar as the official Slovene speaker of the Yugoslav
government in exile for the
Radio London. In summer 1944, he had several speeches directed to the members of the collaborationist
Slovene Home Guard, urging them to join forces with the partisan forces. One of his speeches, titled
A Clear Word from London was printed on leaflets which were dropped by Allied airplanes over Slovenia. In Autumn 1944, Furlan replaced
Izidor Cankar as Minister for Culture and Telecommunication in the Provisional Government. In early 1945, he went to the liberated territories in southern Slovenia together with
Franc Snoj. ==Under the Communist regime==
