United Slovenia

United Slovenia (Slovene: Zedinjena Slovenija or Združena Slovenija) is the name of an unrealized political programme of the Slovene national movement, formulated during the Spring of Nations in 1848. The programme demanded (a) unification of all the Slovene-inhabited areas into one single kingdom under the rule of the Austrian Empire, (b) equal rights of the Slovene language in public, and (c) strongly opposed the planned integration of the Habsburg Monarchy with the German Confederation. The programme failed to meet its main objectives, but it remained the common political program of all currents within the Slovene national movement until World War I.

Following the Vienna Rebellion that forced Ferdinand I to abolish feudalism and adopt a constitution, many nations of the Austrian Empire saw a chance for strengthening their ideas. After the Congress of Vienna in 1815, for the first time in centuries, all Slovenes were under the rule of one emperor. They were, however, divided between different political subdivisions, namely the provinces of Carniola, Styria, Carinthia, Gorizia and Gradisca, Istria, Trieste, Lombardy and Venetia (the Venetian Slovenia) and the Kingdom of Hungary (Prekmurje). In such a fragmentation, a self-government on national basis was impossible.
