Representatives of main political and national organizations and institutions of Serb people in Bosnia and Herzegovina met on 13 October 1990 in Banja Luka and created "Serbian National Council of Bosnia and Herzegovina" as a coordinative and representative political body. During the political crisis that followed the secession of Slovenia and Croatia from the former Yugoslavia on 25 June 1991, a separate Bosnian Serb assembly was founded on 24 October 1991, as the representative body of Serbs of Bosnia and Herzegovina. Bosnian Serbs claimed that this was a necessary step since the Constitution of Bosnia and Herzegovina, at that time, defined that no major changes were to be granted short of a unanimous agreement on all three sides. Bosniaks and Bosnian Croats wanted independence for Bosnia against the Bosnian Serbs' wishes.
