The recent political fate of these Illyrian peoples has been quite various, the Albanians alone preserving their independence continually under the merely nominal rule of the Turks. Religion, also, has affected these Slavs in various ways. Servia owes much of its present peace and prosperity to the practical elimination of the Moslems. Bosnia is still largely Mohammedan, with about a third of its people, according to White ('86), still professing that religion. The significance of this is increased, since it was mainly the upper classes in Bosnia, according to Freeman, who embraced the religion of Islam in order to preserve their power and estates. The conversion was not national, as in the case of the Albanians. Thus social and religious segregation work in harmony to produce discord. With multitudes of Jews monopolizing the commerce of the country and the people thus divided socially as well as in religion, the political unrest in Bosnia certainly seems to require the strong arm of Austrian suzerainty to preserve order. Whatever the theory of the historians as to origins may be, to the anthropologist the modern Illyrians--Serbo-Croatians and Albanians alike--are physically a unit. Two characteristics render this ethnic group distinctive: first, that it comprises some of the tallest men in the world, comparing favorably with the Scotch in this respect; and, secondly, that the Illyrians tend to be among the broadest-headed people known. In general, it would appear that the people, of Herzegovina and northern Albania possess these traits to the most notable degree, while both in the direction of the Save and Danube and of the plains of Thessaly and Epirus they have been attenuated by intermixture. Presumably also toward the east among the Bulgarians in Macedonia and Thrace these characteristics diminish in intensity. Thus, for example, while the Herzegovinians, measured by Weisbach, yielded an average stature of five feet nine inches, the Bosnians were appreciably shorter; and the Dalmatians and Albanians were even more so. Nevertheless, as compared with the Greeks, Bulgars, Turks, or Roumanians, even the shortest of these Slavs stood high. From this specific center outward, especially around the head of the Adriatic Sea, over into Venetia, spreads the influence of this giantism. It confirms, as we have said, the classical theory of an Illyrian cross among the Venetians, extending well up into the Tyrol.
