Ante Trumbić in the context of "Corfu Declaration"

The Corfu Declaration (Serbo-Croatian: Krfska deklaracija, Крфска декларација) was an agreement between the prime minister of Serbia, Nikola Pašić, and the president of the Yugoslav Committee, Ante Trumbić, concluded on the Greek island of Corfu on 20 July 1917. Its purpose was to establish the method of unifying a future common state of the South Slavs living in Serbia, Montenegro and Austria-Hungary after the First World War. Russia's decision to withdraw diplomatic support for Serbia following the February Revolution, as well as the Yugoslav Committee's sidelining by the trialist reform initiatives launched in Austria-Hungary, motivated both sides to attempt to reach an agreement.

Pašić and Trumbić's positions were disparate. Pašić advocated for a centralist government, while Trumbić argued for a federal state, leaving significant powers to federal units and safeguarding national rights. The resulting declaration glossed over the matter of the system of government. As a compromise, it specified only that the common Kingdom of Serbs, Croats and Slovenes would be a constitutional monarchy ruled by the currently reigning Serbian Karađorđević dynasty, deferring most questions to a future Constitutional Assembly. During the discussions, which lasted 35 days, Trumbić had little support for his view from the other members of the Yugoslav Committee, who were preoccupied with the threat posed by Italy, which had been promised territory under the 1915 Treaty of London.
