TRUMBIC, ANTON (1863-1938), Yugoslav statesman, was born at Split. He became successively mayor of Split, and deputy for the city in the Dalmatian Diet, and after 1907 deputy in the Austrian Parliament. In 1905 he and his fellow Dalma tians, Pero Cingrija, Smodlaka and Supilo, as delegates of the Croat National party, worked for the renewed co-operation be tween Serb and Croat, which culminated in the resolutions of Fiume and Zara in 1905, and in the parallel negotiations with the Magyar coalition parties. The programme of reform in Croatia, which was the basis of the agreement with Hungary, was soon frustrated by the intransigent attitude of the Wekerle Govern ment. The Dalmatian Croats, notably Trumbie and Supilo, con sistently endeavoured to improve their relations with the Italians and to combat the constant efforts of Vienna to set the two races at variance.
On the eve of the World War Trumbie crossed the frontier to Venice, where he was joined by Supilo and several other Croat and Serb leaders. The first winter of the war he spent in Rome, hoping to win Italian official support. But Sonnino's anti-Slav policy and the secret agreement concluded between Italy and the Entente at the expense of the Yugoslays in the spring of 1915, forced him to transfer his centre of operations to France and England. The Yugoslav committee, of which TrumbiC was president, was formally constituted in May 1915 in London. In the summer of 1917 he and others negotiated with the exiled Serbian government in Corfu and representatives of all the Serbian parties, the so-called "Declaration of Corfu," which pro vided the basis for a united Yugoslav State. Trumbie met
representative Italians in Dec. 1917 and March 1918, and shared in the arrangements for the congress of oppressed nationalities, held in Rome in April. In Oct. 1918 Trumbie was appointed foreign minister in the Yugoslav provisional government and peace delegate in conjunction with Pagic and Vesnie. He was unable to win support for Yugoslav claims from the Entente, which considered itself still bound to Italy by the secret Treaty of London. The Yugoslays were obliged to come to a direct agreement with Italy, and the Treaty of Rapallo was signed in Nov. 1920.
Trumbies long absence in Paris, coupled with the policy of abstention pursued by the Croat Peasant party under Radie, placed him at a fatal disadvantage when the question of the new constitution came up in 1921. TrumbiC voted in the minority and thereafter drifted steadily into stronger opposition to the new regime in Yugoslavia. His group formed part of the coali tion "bloc" which was in power from July to Oct. 1924, and for a time he effected a working alliance with Radie and committed himself to federalism and even republicanism. The sudden volte face of Radie after the elections of 1925 left Trumbie some what isolated, as the leader of the newly constituted "Croat Federalist Peasant party."
