In my previous comments on the Macedonia name issue, my argument was based on the concept of synecdoche, whereby a part may take the name of the whole. I adduced the examples of the Republic of Azerbaijan, which occupies only a part of historic Azerbaijan (most of it is in Iran, which has the provinces of East and West Azerbaijan); of the Grand Duchy of Luxembourg, which occupies only a part of historic Luxembourg (most of it is in Belgium, which has the province of Luxembourg); and of the United States of America — often called just America — which occupies only a part of the continent of America. So, I argued, let there be a Republic of Macedonia, while Greece can have its provinces of West, Central and East Macedonia.
But the argument that I have lately seen put forth by Greeks, especially on Quora, is that what they call FYROM is not at all, except for a small strip in the south, a part of historic Macedonia, which they identify essentially with the ancient kingdom of Macedon, and whose population they claim to be Greek (justifiably so, as can be read here and here). They thus accuse the Slavs who now call themselves Macedonians (and who, until some time in the 20th century, thought of themselves as Bulgarians) of having appropriated an identity that is not theirs.
Because of the fame of Alexander the Great, Macedonian identity has carried prestige. In graduate school I had a friend who called himself Romanian-American, but he emphasized that he was of Macedonian-Romanian origin (what is now called Aromanian) and therefore a descendant of the Macedonians of Alexander.
But there is precedent for people adopting a prestigious identity that is not originally theirs. The Greeks themselves are a good example: in the Byzantine Empire and under Ottoman rule they called themselves Romans ( Ῥωμαῖοι), because of the prestige of ancient Rome; the Turks called them Rum.
Yet another example is that of the French, who assumed the identity of the Franks, a German tribe (or group of tribes) whose homeland is mainly in western Germany (the region known as Franconia or Franken). The Franks did, indeed, form the ruling class of what eventually became France, but French mythology identified French (franceis, français) with Frank (franc) retroactively to the age of Charlemagne (a heroic figure similar to Alexander), starting with the Song of Roland, and as late as Henri de Bornier’s 1875 play La Fille de Roland, the source of the saying (spoken by Charlemagne in the play) “Every man has two countries, his own and France.” (Modern French historiography, to be sure, uses Francie, not France, to denote the Frankish realm.)
So much for identity. I will write about territory next time.
