Christian II of Saxony (23 September 1583 – 23 June 1611) was Elector of Saxony from 1591 to 1611.
He was born in Dresden, the eldest son of Christian I of Saxony and Sophie of Brandenburg. He belonged to the Albertine line of the House of Wettin.
Christian succeeded his father as Elector of Saxony in 1591 at the age of eight. Because of his youth, his kinsman, Duke Frederick William I of Saxe-Weimar, assumed the regency of the Electorate until 1601, when Christian was declared an adult and began to govern.
In the course of the event that eventually led to the Thirty Years' War, his refusal to join the Union of Auhausen deepened the division between the Protestant German states.
In Dresden, on September 12, 1602, Christian married Hedwig, daughter of the King Frederick II of Denmark. This marriage was childless. He died in Dresden in 1611.
Having left no issue, on his death his brother John George succeeded him as Elector.

John George I (German: Johann Georg I.) (5 March 1585 – 8 October 1656) was Elector of Saxony from 1611 to 1656. Born in Dresden, John George was the second son of the Elector Christian I and Sophie of Brandenburg.[1] He belonged to the Albertine line of the House of Wettin.
John George succeeded to the electorate on 23 June 1611 on the death of his elder brother, Christian II. The geographical position of the Electorate of Saxony rather than her high standing among the German Protestants gave her ruler much importance during the Thirty Years' War. At the beginning of his reign, however, the new elector took up a somewhat detached position. His personal allegiance to Lutheranism was sound, but he liked neither the growing strength of Brandenburg nor the increasing prestige of the Palatinate; the adherence of the other branches of the Saxon ruling house to Protestantism seemed to him to suggest that the head of the Electorate of Saxony should throw his weight into the other scale, and he was prepared to favour the advances of the Habsburgs and the Roman Catholic party.
Thus John George was easily induced to vote for the election of Ferdinand, Archduke of Styria, as emperor in August 1619, an action which nullified the anticipated opposition of the Protestant electors. The new emperor secured the help of John George for the impending campaign in Bohemia by promising that he should be undisturbed in his possession of certain ecclesiastical lands. Carrying out his share of the bargain by occupying Silesia and Lusatia, where he displayed much clemency, the Saxon elector had thus some part in driving Frederick V, elector palatine of the Rhine, from Bohemia and in crushing Protestantism in that country, the crown of which he himself had previously refused.
Gradually, however, he was made uneasy by the obvious trend of the imperial policy towards the annihilation of Protestantism, and by a dread lest the ecclesiastical lands should be taken from him; and the issue of the edict of restitution in March 1629 put the capstone to his fears. Still, although clamouring vainly for the exemption of the electorate from the area covered by the edict, John George took no decisive measures to break his alliance with the emperor. He did, indeed, in February 1631 call a meeting of Protestant princes at Leipzig, but in spite of the appeals of the preacher Matthias Hoe von Hohenegg (1580–1645) he contented himself with a formal protest.

Meanwhile, Gustavus Adolphus had landed in Germany, aiming to relieve Magdeburg. Gustavus attempted to conclude an alliance with John George to allow him to cross the Elbe at Wittenberg, but John George remained hesitant to join the Protestant cause and the discussions went nowhere. Hoping that an alliance would be concluded eventually, Gustavus avoided any military action.
Tilly, commander of the main imperial force, was also concerned about the possibility of an alliance, no matter how unlikely it was at the time. In order to preempt any such move, he invaded Saxony and started to ravage the countryside. This had the effect of driving John George into the alliance he had hoped to preempt, which was concluded in September 1631. The Saxon troops were present at the battle of Breitenfeld, but were routed by the imperialists, the elector himself seeking safety in flight.[1]
Nevertheless, he soon took the offensive. Marching into Bohemia the Saxons occupied Prague, but John George soon began to negotiate for peace and consequently his soldiers offered little resistance to Wallenstein, who drove them back into Saxony. However, for the present the efforts of Gustavus Adolphus prevented the elector from deserting him, but the position was changed by the death of the king at Lützen in 1632, and the refusal of Saxony to join the Protestant league under Swedish leadership.[1]
Still letting his troops fight in a desultory fashion against the imperialists, John George again negotiated for peace, and in May 1635 he concluded the important treaty of Prague with Ferdinand II. His reward was Lusatia and certain other additions of territory; the retention by his son Augustus of the archbishopric of Magdeburg; and some concessions with regard to the edict of restitution. Almost at once he declared war upon the Swedes, but in October 1636 he was beaten at Wittstock; and Saxony, ravaged impartially by both sides, was soon in a deplorable condition. At length in September 1645 the elector was compelled to agree to a truce with the Swedes, who, however, retained Leipzig; and as far as Saxony was concerned this ended the Thirty Years' War. After the peace of Westphalia, which with regard to Saxony did little more than confirm the treaty of Prague, John George died on 8 October 1656.

August of Saxony (7 September 1589, Dresden – 26 December 1615, Naumburg) from the Albertine line of the House of Wettin was Administrator of the diocese of Naumburg-Zeitz.
August was the youngest son of the elector Christian I of Saxony (1560–1591) from his marriage to Sophie of Brandenburg (1568–1622), daughter of the elector John George of Brandenburg. His older brothers Christian II and John George I were successively Electors of Saxony. From the latter August received an annual pension of 21,000 florins and the district of Senftenberg.
August graduated from the University of Wittenberg, where Wolfgang Hirschbach had been entrusted the task to guide this young nobleman in his training. During this period he held from the winter semester 1601 until 1606, the position of Rector Magnificus; the academic aspect of this office was performed by a pro-rector.
He married on 1 January 1612 in Dresden to Elisabeth of Brunswick-Wolfenbüttel (1593–1650), daughter of the Duke Henry Julius of Brunswick-Wolfenbüttel. They had no children.
He died suddenly at the age of 26 in Dresden and was buried in the Freiberg Cathedral.
