What a load of crap. Serbia was established in 1878 at the 'Congress of Berlin'.
Again, some incredible BS. The AVNOJ is clear on that, the constituent nations had the right to leave and join the federation, as Yugoslavia was a federation of it's peoples. The Albanians were not constituent, nor a slavic nation and they did not had the right to self-determination according to the constitution. http://www.arhiv.sv.gov.yu/a100008g.htm
Kosova and Voivodina were actually established before Serbia: Kosova in January 1944, Voivodina in March 1944, Serbia only in November 1944.
What a load of crap. Serbia was established in 1878 at the 'Congress of Berlin'.
