MODERN HISTORY OF YUGOSLAVIA, SERBIA AND MONTENEGRO ,(WORLD HERALDRY VIDEO BUT MODIFIED).

Montenegro's history spans from Illyrian tribes and Roman rule to centuries of Byzantine, Serbian, and Ottoman influence, eventually establishing de facto autonomy under prince-bishops in the 17th and 18th centuries. It gained formal independence in 1878, became a kingdom in 1910, was incorporated into various Yugoslav states after World War I, and peacefully separated from Serbia in 2006 to become a fully sovereign nation again.
=================================
The history of Serbia covers the historical development of Serbia and of its predecessor states, from the Early Stone Age to the present state, as well as that of the Serbian people and of the areas they ruled historically. Serbian habitation and rule has varied much through the ages, and as a result the history of Serbia is similarly elastic in what it includes.

After early Slavs first appeared in the Balkans in the 6th and 7th centuries, they mixed with local Byzantine subjects, descendants of Paleo-Balkan tribes, such as the Thracian, Dacian, Roman, Illyrian and former Roman colonists. The First Serbian Principality was established in the 8th century by the Vlastimirovići dynasty ruling over modern-day Montenegro, Bosnia, Dalmatia, and Serbia. It evolved into a Grand Principality by the 11th century, and in 1217 the Kingdom and national church (Serbian Orthodox Church) were established, under the Nemanjić dynasty. In 1345 the Serbian Empire was established, spanning most of the Balkan peninsula. In 1540 Serbia became a part of the Ottoman Empire.

A significant number of Serbs migrated north to the Kingdom of Hungary, forming what would later become Serbian Vojvodina. Serbian revolution against Ottoman rule in 1817 marked the birth of the Principality of Serbia, which achieved de facto independence in 1867 and gained full recognition by the Great Powers in the Berlin Congress of 1878. As a victor in the Balkan Wars of 1912–1913, Serbia regained Vardar Macedonia, Kosovo and Metohija and Raška. In late 1918, with the defeat of the Austro-Hungarian empire, Serbia was expanded to include regions of the former Serbian Vojvodina. Serbia was united with other Austro-Hungarian provinces into a pan-Slavic State of Slovenes, Croats and Serbs; the Kingdom of Serbia joined the union on 1 December 1918 and the country was named the Kingdom of Serbs, Croats and Slovenes.

Serbia achieved its current borders at the end of World War II, when it became a federal unit within the Federal People's Republic of Yugoslavia (proclaimed in November 1945). After the dissolution of Yugoslavia in a series of wars in the 1990s, Serbia once again became an independent state on 5 June 2006, following the breakup of a short-lived union with Montenegro.
