Augustus (b. Dresden, 23 October 1569 – d. Dresden, 12 February 1570). Adolf (b. Stolpen, 8 August 1571 – d. Dresden, 12 March 1572). Frederick (b. Annaberg, 18 June 1575 – d. Annaberg, 24 January 1577). Soon after his marriage, Augustus desired a more imposing establishment. The result was that Maurice made more generous provision for his brother, who acted as Regent of Saxony in 1552 during the absence of the elector. Augustus was on a visit to Denmark when by Maurice's death in July 1553 he became elector of Saxony. Elector of Saxony The first care of the new elector was to come to terms with John Frederick, and to strengthen his own hold upon the electoral position. This object was secured by a treaty made at Naumburg in February 1554, when, in return for the grant of Altenburg and other lands, John Frederick recognized Augustus as elector of Saxony. The elector, however, was continually haunted by the fear that the Ernestines would attempt to deprive him of the coveted dignity, and his policy both in Saxony and the wider Holy Roman Empire was coloured by this fear.

To this policy may be traced his share in bringing about the religious Peace of Augsburg treaty in 1555, his tortuous conduct at the diet of Augsburg eleven years later, and his reluctance to break entirely with the Calvinists. His policy of religious peace was also promoted by the marriage he negotiated between his niece Anna and the then-Catholic Prince of Orange, at the time one of the chief Habsburg vassals in the Netherlands, in 1561.

For a time it seemed possible that the Saxon elector would support his son-in-law
