In October 1918, the State of Slovenes, Croats and Serbs was declared from the liberated lands from the Austro-Hungarian Empire in what would become the first incarnation of a Yugoslav state. This did not achieve recognition. In December, the State united with the Kingdom of Serbia (which had just expanded its borders after World War I to incorporate the Vojvodina region, and previously independent Montenegro) to form the Kingdom of Serbs, Croats and Slovenes. The Committee's task was accomplished.
