The 19th century also saw a revival of culture in Slovene, accompanied by a Romantic nationalist quest for cultural and political autonomy. The idea of a United Slovenia, first advanced during the revolutions of 1848, became the common platform of most Slovenian parties and political movements in Austria-Hungary. During the same period, Yugoslavism, an ideology stressing the unity of all South Slavic peoples, spread as a reaction to Pan-German nationalism and Italian irredentism.
