We need not doubt, the Brandenburg House--old Kurfurst Joachim II. still alive, and thrifty Johann George the Heir-Apparent--kept a watchful eye on those emergencies. But it was difficult to interfere directly; the native Prussian Raths were very jealous, and Poland itself was a ticklish Sovereignty to deal with. Albert Friedrich being still a Minor, the Polish King, Sigismund, proposed to undertake the guardianship of him, as became a superior lord to a subject vassal on such an occasion. But the Prussian Raths assured his Majesty, "Their young Prince was of such a lively intellect, he was perfectly fit to conduct the affairs of the Government," especially with such a Body of expert Councillors to help him, "and might be at once declared of age." Which was accordingly the course followed; Poland caring little for it; Brandenburg digesting the arrangement as it could. And thus it continued for some years, even under new difficulties that arose; the official Clique of Raths being the real Government of the Country; and poor young Albert Friedrich bursting out occasionally into tears against them, occasionally into futile humors of a fiery nature. Osiander-Theology, and the battle of the 'DOXIES, ran very high; nor was Prussian Officiality a beautiful thing. These Prussian Raths, and the Prussian RITTERSCHAFT generally (Knightage, Land-Aristocracy), which had its STANDE (States: or meetings of Parliament after a sort), were all along of a mutinous, contumacious humor. The idea had got into their minds, That they were by birth what the ancient Ritters by election had been; entitled, fit or not fit, to share the Government promotions among them: "The Duke is hereditary in his office; why not we? All Offices, are they not, by nature, ours to share among us?" The Duke's notion, again, was to have the work of his Offices effectually done; small matter by whom: the Ritters looked less to that side of the question;--regarded any "Foreigner" (German-Anspacher, or other Non-Prussian), whatever his merit, as an intruder, usurper, or kind of thief, when seen in office. Their contentions, contumacies and pretensions were accordingly manifold. They had dreams of an "Aristocratic Republic, with the Sovereign reduced to zero," like what their Polish neighbors grew to. They had various dreams; and individuals among them broke out, from time to time, into high acts of insolence and mutiny. It took a hundred and fifty years of Brandenburg horse-breaking, sometimes with sharp manipulation and a potent curb-bit, to dispossess them of that notion, and make them go steadily in harness. Which also, however, was at last got done by the Hohenzollerns. OF DUKE ALBERT FRIEDRICH'S MARRIAGE: WHO HIS WIFE WAS, AND WHAT HER POSSIBLE DOWRY.
