MITBELEHNUNG (Co-infeftment) in Preussen;--whereby is solemnly acknowledged the right of Joachim and his Posterity to the reversion of Preussen, should the Culmbach Line of Duke Albert happen to fail. It was a thing Joachim long strove for; till at length his Father-in-law did, some twenty years hence, concede it him. [Date, Lublin, 19th July, 1568: Pauli, iii. 177-179, 193; Rentsch, p. 457; Stenzel, i. 341, 342.] Should Albert's Line fail, then, the other Culmbachers get Preussen; should the Culmbachers all fail, the Berlin Brandenburgers get it. The Culmbachers are at this time rather scarce of heirs: poor Alcibiades died childless, as we know, and Casimir's Line is extinct; Duke Albert himself has left only one Son, who now succeeds in Preussen; still young, and not of the best omens. Margraf George the Pious, he left only George Friedrich; an excellent man, who is now prosperous in the world, and wedded long since, but has no children. So that, between Joachim's Line and Preussen there are only two intermediate heirs;--and it was a thing eminently worth looking after. Nor has it wanted that. And so Kurfurst Joachim, almost at the end of his course, has now made sure of it. JOACHIM MAKES "HERITAGE-BROTHERHOOD" WITH THE DUKE OF LIEGNITZ. Another feat of like nature Joachim II. had long ago achieved; which likewise in the long-run proved important in his Family, and in the History of the world: an "ERBVERBRUDERUNG," so they term it, with the Duke of Liegnitz,--date 1537. ERBVERBRUDERUNG ("Heritage-brotherhood," meaning Covenant to succeed reciprocally on Failure of Heirs to either) had in all times been a common paction among German Princes well affected to each other. Friedrich II., the then Duke of Liegnitz, we have transiently seen, was related to the Family; he had been extremely helpful in bringing his young friend Albert of Preussen's affairs to a good issue,--whose Niece, withal, he had wedded:--in fact, he was a close friend of this our Joachim's; and there had long been a growing connection between the two Houses, by intermarriages and good offices.
