There is also another part of the map that might be wrong. It is disputed how long the history of the Romanian language in Romania is. I am presently reading a book about Kosovo, called Kosovo: A short history, bye Noel Malcolm. He discusses various groups that have had a connection with the Kosovo area, among them the Albanians and the Vlachs (Romanians). On page 40 he writes: "It is, therefore, in the uplands of the Kosovo area (particularly, but not only, on the western side, including parts of Montenegro) that this Albanian-Vlach symbiosis probably developed. All the evidence comes together at this point. What it suggests is that the Kosovo region, together with at least part of northern Albania, was the crucial focus of two distinct, but interlinked ethnic histories: The surival of the Albanians, and the emergence of the Romanians and Vlachs. One large group of Vlachs seem to have broken away and moved southwards by the ninth or tenth centuries, The proto-Romanians stayed in contact with the Albanians significantly longer, before drifting north-eastwards and crossing the Danube in the twelfth century".
