relinquish part of Vardar Macedonia to Bulgaria so that the latter would enter the war on the Entente side. Both Pašić and regent Alexander were against this as they considered it to be the betrayal of the Croatians, Slovenians and Serbian sacrifices in the Balkan Wars, as negotiations for the future South Slav state already began. However, Pašić and king Peter were not personally much for the Yugoslav idea unlike the regent who pushed the issue for creating as large a state as possible. Serbia refused the pact and was attacked by Austria-Hungary, Germany and Bulgaria. The Government and the army retreated to the south in the direction of Greece, but were cut off by Bulgarian forces and had to go through Albania and to the Greek island of Corfu where the Corfu Declaration was signed in 1917 preparing the ground for the future South Slav state of Yugoslavia. Creation of the Kingdom of Serbs, Croats and Slovenes The Kingdom of Serbs, Croats and Slovenes (SHS) was officially proclaimed on 1 December 1918, and, being the Prime Minister of Serbia at that time, Pašić was generally considered the de facto Prime Minister of the new South Slav state, as well. The political agreement was reached that Pašić would continue on as Prime Minister when the first government of the new state was to be formed, but as a result of his longtime dislike of Pašić, regent Alexander nominated Stojan Protić to form the government. Consequently, Pašić stepped down on 20 December 1918. Despite being removed from the government, as the most experienced of politicians, Nikola Pašić was the main negotiator for the new state at the Paris Peace Conference of 1919. In an effort to secure the maximalist agenda of the regent, he did not push on the question of the Czech Corridor, Timișoara, and Szeged, managed to secure borders with Albania and Bulgaria, but failed to annex Fiume (which became an independent state) and most of Carinthia (which remained part of Austria). At the time when Benito Mussolini was willing to modify the Treaty of Rapallo, which cut off a quarter of Slovene ethnic territory from the remaining three-quarters of Slovenes living in the Kingdom of SHS, in order to annex the independent state of Rijeka to Italy, Pašić's attempts to correct the borders at Postojna and Idrija were undermined by regent Alexander preferring "good relations" with Italy.
