To the south-east lay the _Bohemian_ lands, whose history has been somewhat different. ♦Bohemia a fief, 928.♦ The duchy, afterwards kingdom, of _Bohemia_, became, early in the tenth century, a fief of the German kingdom. ♦Becomes a kingdom, 1198. | 1003.♦ From that time ever afterwards, save during one moment of passing Polish annexation, it remained one of its principal members, ruled, as long as the Empire lasted, by princes holding electoral rank. The boundaries of the kingdom itself have hardly varied at all. ♦Moravia. | 1019.♦ The dependent marchland of _Moravia_ to the east, the remnant of the great Moravian kingdom whose history will come more fittingly in another chapter, fluctuated for a long while between Hungarian, Polish, and Bohemian supremacy. But from the early part of the eleventh century it remained under Bohemian rule, and therefore under Imperial superiority. ♦More distant Slavonic states.♦ To the east of this nearer zone of Slavonic dependencies, lay another range of Slavonic states, some of which were gradually incorporated with the German kingdom, while others remained distinct down to modern times. ♦Pomerania.♦ _Pomerania_ on the Baltic coast is a name which has often changed both its geographical extent and its political allegiance. The eastern part of the land now so called lay open, as will be hereafter seen, to the occupation of the Pole, and its western part to that of the Dane. ♦Native princes go on.♦ But in the end it took its place on the map in the form of two duchies, ruled, like Mecklenburg, by native princes under Imperial supremacy. ♦Polish frontier.♦ South of Pomerania, the German march bordered on the growing power of _Poland_, and between Poland and Hungary lay the northern _Croatia_ or _Chrobatia_. The German supremacy seems sometimes to have been extended as far as the Wartha, and, in the Chrobatian land, even beyond the Vistula. ♦Occasional homage of the Polish kings.♦ But this occupation was quite momentary; Poland grew up, like Hungary, as a kingdom, some of whose dukes and kings admitted the Imperial supremacy, but which gradually became wholly independent. ♦Silesia Polish, 999.♦ The border province of _Silesia_, after some fluctuations between Bohemia and Poland, became definitely Polish at the end of the tenth century. ♦Bohemian, 1289-1327.♦ Afterwards it was divided into several principalities, whose dukes passed under Bohemian vassalage, and so became members of the Empire. Thus in the course of some ages, a boundary was drawn between Germany and Poland which lasted down to modern times. * * * * * ♦Extension of the Empire to the east.♦
