Unknown Archont
"The Unknown Archont"
The House of Vlastimirovic is named for Knez Vlastimir who was the great great grandson of the Unknown Archont who led the Serbs to the Balkans from White Serbia (modern day Poland, Slovakia and Ukraine) during the reign of Byzantine emperor Heraclius somewhere between 610 – 641.
The Unknown Archont must have been an incredible leader. He lead the Serbs in White Serbia, then defeated the Eurasian Avars in central Europe, then lead the Serb tribe thousands of miles to the shores of the Adriatic Sea, the Sava river and the Morava river valley after negotiating this land with Heraclius as payment for having defeated the Eurasian Avars. Constantine VII Porphyrogenitos writes in De Administrando Imperio that the Serbs received in Rascia / Raska, Zachumlie/Zahumlje, Trebounia/Travunia, Zeta/Duklja, Bosnia/Bosna and Pagania/Paganija. Internal struggles started immediately after the Serbs settled these parts.
The Unknown Archont was displaced early after the settlement of the Serbs. Other chiefs vied for power. The Unknown Archont died in 680.
