With the establishment of Yugoslavia as a state that consisted of several nations such as Croats, Slovenes, Bosnians, Albanians, Macedonians and Serbs, there will constantly be attempts to dominate other nations. For Serbia, the Yugoslav state will only be a tool for Serbian domination, which, in turn, stimulated Croatian national opposition. Nationalism will come to the fore mostly from the years 1844 with the infamous "Nacertania" program until the end of the Second World War. Serbian nationalism will also be emphasized during Tito's leadership, with the program of the Serbian Academy of Sciences and Arts in 1986 and its implementation by Slobodan Milosevic. The Serbs never stopped these forms of war even with the ethnic Albanians of Kosovo and the Albanians who lived in other territories in the former Yugoslavia, but they managed to adapt them, depending on the political currents in the world, and continued the ethnocide that can be taken as an example flagrant application of silent fascism that acted in the institutional framework, without any serious reaction from the outside.
