In this article the author describes the main characteristics of parliamentary life in the Kingdom of Croatia-Slavonia during the Austro-Hungarian period. The Croatian Sabor (Parliament) began to function as a representative body in June 1848. According to the decrees of the Croatian-Hungarian Agreement (1868), the Croatian parliament was a legislative body that had jurisdiction over those affairs in which Croatia was granted autonomy: internal administration, the judiciary, education and culture. After the emergence of a strong national movement, and large demonstrations against the regime, Khuen-Héderváry was appointed to the office of Ban. He was appointed to break the resistance of the nationalist parties who opposed and obstructed the proper functioning of dualism, the constitutional arrangement between Budapest and Vienna which inhibited the development of a separate Croatian nation and state.
