 Ante Starčević founded the Party of Rights in Croatia in 1861 that argued that legally, Croatia's right of statehood had never been abrogated by the Habsburg monarchy and thus Croatia was legally entitled to be an independent state.Starčević regarded Croatia to include not only present-day Croatia but also what is now Bosnia and Herzegovina, Slovenia (Duchy of Carinthia, Carniola, Styria) and parts of Serbia (Sanjak of Novi Pazar, Syrmia)—all people in this Greater Croatia whether Catholic, Muslim, or Orthodox were defined as Croats.During the 19th to mid-20th century Croatian nationalists competed with the increasingly Pan-Slavic Illyrian movement and Yugoslavists over the identity of Croats.
