Speaking generally, the Southern Slavs are divided into Slovenes, Serbo-Croats, and Bulgarians, but of these three branches only the Slovenes and Serbo-Croats are racially identical. In speaking of a political Southern Slav State, a state which would in the future dominate the _whole_ of the Balkan Peninsula, it would be wrong not to include the Bulgarian nation. However, the Serbo-Croats form the principal cultural “unit” among the Southern Slavs, and after them come the Slovenes. The nucleus, the life-giving element of the Southern Slav family and its culture, is formed by the Southern Slavs of Serbia, Old Serbia, Montenegro, Bosnia, Hercegovina, Croatia, Dalmatia and Serbian Hungary, or, to give them their collective name, by the Serbo-Croats. The Serbo-Croats, and more especially the Serbians proper (Serbians of Old Serbia and Serbia), have always led the vanguard of Serbo-Croatian political life; the two greatest cultural achievements of the Southern Slav race, to wit, the national poetry and the individual architecture and sculpture of Ivan Meštrović, have always been associated with the Serbians of Serbia. The fall of the Serbian Empire forms the chief theme of Meštrović’s art, no less than of Southern Slav national poetry—and thus it has become usual, if not strictly correct, to speak of all Southern Slav poetry as Serbian national poetry, and of the great Southern Slav artist as the great Serbian artist. We speak of the Southern Slav poetry and of Ivan Meštrović, our Southern Slav Michelangelo, as “buried treasures.” In a sense, all Slav civilization may be called a buried treasure. Russian and Slav literature as a whole, is far greater than its reputation in Western Europe. Ottokar Brezina, the celebrated Csech poet, is translated and read in Slavophobe Germany, but not in allied France and England; because in these days nations are more often brought into contact by war and travel than by civilization and our common humanity.
