The Dalmatian Croat politician Ante Trumbić became a prominent South Slavic leader during the war and led the Yugoslav Committee that lobbied the Allies to support the creation of an independent Yugoslavia. Trumbić faced initial hostility from Serbian Prime Minister Nikola Pašić, who preferred an enlarged Serbia over a unified Yugoslav state. However, both Pašić and Trumbić agreed to a compromise, which was delivered at the Corfu Declaration on 20 July 1917 that advocated the creation of a united state of Serbs, Croats, and Slovenes to be led by the Serbian House of Karađorđević.
