 Another collateral line founded in 1657 was that of Saxe-Zeitz, which became extinct in 1759.Members of this line who became Catholic were Christian Augustus (died 1725), Cardinal Archbishop of Gran in Esztergom, Hungary and Maurice Adolphus, Bishop of Leitmeritz in Bohemia (died 1759).The most zealous promoter of the Catholic faith in Saxony was the Austrian Archduchess Maria Josepha, daughter of Emperor Joseph I, who in 1719 married Frederick Augustus, later the second elector of that name.
