Whilst in the regions adjoining the Oder, and still farther off by the shores of the Baltic, the German race, proud of their recent conquest over the Sclaves, desired to improve themselves by union with Germany, a great Sclave population had arisen in the middle of the German states, the toughest and most stable of all that family: it was firmly incorporated in the Empire, and had long been under the influence of German culture. Prague in the beginning of the fifteenth century might have passed for a German city, for not only in its laws and commerce, but also in science and art it exhibited all the vigour and independence of German life. About 1289 the King of Bohemia rode as a German elector to the election of the Emperor, and waved the golden glass at the coronation; the Bohemian minstrels and chroniclers wrote in the Swabian language and style, and Bohemian artists painted pictures of saints and windows for the German churches. Under the Luxemburgers Bohemia became the centre of the empire. The Bohemian throne was adorned with the German Imperial eagle and crown, and the flower of Germany's youth flocked to the many-turreted Moldavian city, in order to win in the first German university a nobler patent of nobility than the sword could give. It seemed then for a considerable period as if this fine compact Sclave country, lying with its mountain ramparts in the midst of Germany like a gigantic fortress, was likely to become the kernel of a great united empire, spreading far beyond the Rhine on the west, and to the Vistula on the east, or even perhaps to the swamps of the Theis. But just at this time an energetic reaction of Sclave popular feeling was roused in Bohemia against the Germans, and a long struggle ensued which fearfully shook the political, religious, and social life of Germany, rent the unity of the Roman Catholic Church, weakened the empire and threw it into confusion, depopulated large districts by a war full of cruelty, and amidst the flames of burning cities and the waning of millions, gave the death-blow to the Holy Roman Empire of the middle ages. It was the peculiar destiny of Germany that this great struggle should first break out among the teachers and scholars in the halls of the universities, and that the funeral pile of a Bohemian professor should give a new direction to the policy of German princes and people.
