Brandenburg–Prussia's claims in Silesia were based, in part, on a 1537 inheritance treaty between the Silesian Piast[1] Duke Frederick II of Legnica [2]and the Hohenzollern Prince-Elector[3]JoachimII Hector of Brandenburg [4], whereby the Silesian Duchies of Liegnitz[5], Wohlau[6]and Brieg[7] were to pass to the Hohenzollerns of Brandenburg should the Piast dynasty in Silesia become extinct. At the time, the Habsburg King FerdinandI[8] of Bohemia (Silesia's feudal overlord[9]) rejected the agreement and pressed the Hohenzollerns to repudiate it. In 1603, Hohenzollern Elector JoachimIII Frederick of Brandenburg[10] separately inherited the Silesian Duchy of Jägerndorf[11] from his cousin, Margrave George Frederick of Brandenburg-Ansbach [12], and installed his second son, Johann Georg[13], as duke.
In the 1618 Bohemian Revolt [14]and the ensuing Thirty Years' War[15], Johann Georg joined the Silesian estates in revolt against the Catholic Holy Roman Emperor FerdinandII. After the Catholic victory in the 1621 Battle of White Mountain[16], the Emperor confiscated Johann Georg's duchy and refused to return it to his heirs after his death, but the Hohenzollerns of Brandenburg continued to assert themselves as the legitimate rulers of Jägerndorf. In 1675 the "Great Elector" Frederick William of Brandenburg[17] laid claim to Liegnitz, Wohlau and Brieg when the Silesian Piast line ended with the death of Duke George William of Liegnitz[18], but the Habsburg Emperor disregarded the Hohenzollern claims and the lands escheated to the crown.
In 1685, when Austria was engaged in the Great Turkish War[19], Emperor Leopold I[20] gave Great Elector Frederick William immediate control of the Silesian exclave[21] of Schwiebus[22] in return for military support against the Turks and the surrender of the outstanding Hohenzollern claims in Silesia. After the accession of the Great Elector's son and successor, FrederickIII of Brandenburg[23], the Emperor took back control of Schwiebus in 1694, claiming that the territory had only been personally assigned to the late Great Elector for life. As a young prince, FrederickIII had secretly agreed to this repossession in return for Leopold's payment of some of his debts, but as monarch he repudiated the agreement and reasserted the old Hohenzollern claims to Jägerndorf and the Silesian Piast heritage.
