 The Illyrian movement was centred in Croatia and Croatian politics, believing that a Croatian renaissance was necessary to be achieved prior to the movement's long-term goal of ethnic and political unification of South Slavs.Ljudevit Gaj, a key figure of the Illyrian movement declared Croats and Serbs to be the two major subgroups of the South Slav or "Illyrian" nationality, which also included Slovenes, and South Slavic inhabitants of Bosnia and Herzegovina, Bulgaria, and Montenegro.In spite of its pan-South Slavic ideals, the Illyrian movement was dominated by upper-class Croats, originally with little support amongst Serbs, Slovenes, or other South Slavic peoples.
