 In 1518 the bishops of Lebus acquired the Lower Lusatian lordships of Beeskow and Storkow.As since 1513 the House of Hohenzollern also had held the office of the Magdeburg archbishops, Lebus finally turned Protestant and was secularized in 1555.The former bishopric was finally incorporated into Brandenburg, when in 1598 the last Lutheran administrator Joachim Frederick of Hohenzollern became elector.
