with Ante Trumbić, a Croatian emigrant from Dalmatia, and joined the Yugoslav Committee, a political interest group formed by South Slavs from Austria-Hungary aimed at the unification of the South Slavic peoples in an independent state. In 1917, he was among the signers of the Corfu Declaration, a joined political statement of the Yugoslav Committee and the representatives of the Kingdom of Serbia, which was the first step in the creation of Yugoslavia. After the end of War, Vošnjak moved to Paris, where he worked for the Yugoslav delegation at the Versailles Peace Conference. In 1920, he returned to his homeland, and was elected to the constitutional assembly of the Kingdom of Serbs, Croats and Slovenes on the list of the liberal Slovene Independent Agrarian Party. In the Assembly, Vošnjak strongly advocated a centralist and monarchist framework of the new country, against most deputies from Slovenia, Croatia and Dalmatia, who favoured federalism. In February 1921, Vošnjak attacked the Autonomist Declaration, signed by some of the most prominent Slovene liberal and progressive intellectuals, who demanded cultural and political autonomy for Slovenia within Yugoslavia. Between 1923 and 1924, he served as ambassador of the Kingdom of Serbs, Croats and Slovenes to Czechoslovakia. In 1924, he settled in Belgrade. During the Nazi German occupation of Serbia between 1941 and 1944, Vošnjak supported the Chetnik underground network of general Draža Mihajlović. After the Communists took power in Yugoslavia in 1945, Vošnjak emigrated to the United States. He worked at the Columbia University Libraries and later as an expert for the House Un-American Activities Committee. Between 1952 and 1953, he lectured at the University of California, Berkeley on "Government and Politics in the Balkan Countries". He died in Washington, D.C., in 1955.
