The reason of this state of things is this: ever since the time of Charlemagne, the Germans have directed their most constant and persevering efforts to the conquest, colonization, or, at least, civilization of the east of Europe. The conquest of the feudal nobility between the Elbe and the Oder, and the feudal colonies of the military orders of knights in Prussia and Livonia, only laid the ground for a far more extensive and effective system of Germanization by the trading and manufacturing middle classes, which in Germany, as in the rest of Western Europe, rose into social and political importance since the fifteenth century. The Slavonians, and particularly the Western Slavonians (Poles and Tschechs), are essentially an agricultural race; trade and manufactures never were in great favor with them. The consequence was that, with the increase of population and the origin of cities in these regions, the production of all articles of manufacture fell into the hands of German immigrants, and the exchange of these commodities against agricultural produce became the exclusive monopoly of the Jews, who, if they belong to any nationality, are in these countries certainly rather Germans than Slavonians. This has been, though in a less degree, the case in all the east of Europe. The handicraftsman, the small shopkeeper, the petty manufacturer, is a German up to this day in Petersburg, Pesth, Jassy, and even Constantinople; while the money-lender, the publican, the hawker--a very important man in these thinly populated countries--is very generally a Jew, whose native tongue is a horribly corrupted German. The importance of the German element in the Slavonic frontier localities, thus rising with the growth of towns, trade and manufactures, was still increased when it was found necessary to import almost every element of mental culture from Germany; after the German merchant and handicraftsman, the German clergyman, the German school-master, the German _savant_ came to establish himself upon Slavonic soil. And lastly, the iron thread of conquering armies, or the cautious, well-premeditated grasp of diplomacy, not only followed, but many times went ahead of the slow but sure advance of denationalization by social development. Thus, great parts of Western Prussia and Posen have been Germanized since the first partition of Poland, by sales and grants of public domains to German colonists, by encouragements given to German capitalists for the establishment of manufactories, etc., in those neighborhoods, and very often, too, by excessively despotic measures against the Polish inhabitants of the country.
