The decision of the second session of AVNOJ on the federalization of Yugoslavia in 1943 was regarded as the recognition of this Brotherhood and Unity principle.
Every individual was entitled to the expression of their own culture, while the ethnic groups had an oath to one another to maintain peaceful relations.
[6] Several prominent persons from former Yugoslavia were convicted for activities deemed to threaten the brotherhood and unity, such as acts of chauvinist propaganda, separatism and irredentism.
Among them were Serbian radical Vojislav Šešelj,[7] former presidents of Bosnia and Herzegovina (Alija Izetbegović) and Croatia (Franjo Tuđman and Stjepan Mesić),[8][9] and others.
One Kosovar Albanian, Adem Demaçi, was imprisoned and accused of nationalist machinations.
