If the formation of the South Slav peoples was a mechanical and political process it would not be impossible that it might recur in present times. Within the South Slav language complex there are several branches outside the Serbian and Bulgarian political units; these are the Macedonian dialects. These branches, since they are closely allied, naturally have some connection linking them more closely with Bulgarian in the east and Serbian in the north.
These branches have been given various names at various times but it was not until the last quarter of the nineteenth century that these names overlapped so much as to displace one another. These various names did not properly catch on, and gradually they began to give way until finally they were replaced by the natural description Slav" with a "Macedonian" reflection from the geographical area in which they were distributed.
The people who spoke these dialects had once been called "Slavs" and later either "Serbs" or "Bulgarians" until the rivalry between these two names made them both alien to the Macedonian Slavs, who started calling themselves after the old geographical name of their country.
The name Macedonian was first used by the Macedonian Slavs as a geographical term to indicate their origin. This name is well known to the Macedonian Slavs and all of them use it to describe themselves. Since the formation of nationalities is a political and mechanical process, all the necessary conditions exist for Macedonia to break off as an independent ethnographic region.
There is not any question as regards theirs identifications.
