Illyrian movement
The Illyrian movement (Croatian: Ilirski pokret; Slovene: Ilirsko gibanje) was a pan-South-Slavic cultural and political campaign with roots in the early modern period, and revived by a group of young Croatian intellectuals during the first half of the 19th century, around the years of 1835 to 1863. This movement aimed to create a Croatian national establishment in Austria-Hungary through linguistic and ethnic unity, and through it lay the foundation for cultural and linguistic unification of all South Slavs under the revived umbrella term Illyrian.
