Trolling by Bogdan and Constantzeanu Bulgar necropoles have been discovered on the following sites Topola Durankulak Dobrich region and Istria Obarshia Noua Izvorul Sultana in presentday Romania And this is according to a source from the s perhaps many more have been found after that date Should I also remind you that the first Bulgarian capital Pliska lies around  km from the boundary of Southern Dobruja  As for the Romanian majority in northern Dobruja we have talked at length with you about this Bogdan and such a thing did not exist AT ALL until the beginning of the th century and even then the Romanians had ONLY a relative majority   Third of all I want to ask what the hell does Cadrilater do in the category Historical Romanian Regions The fact that it was ruled for  years by Romania and subjected to intensive colonisation does not make it a historical Romanian region the category falls sorry
